| CVE-2026-68473 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: powerpc/uaccess: correct check for CONFIG_PPC_E500 in mask_user_address() mask_user_address() incorrectly checks for CONFIG_E500 instead of CONFIG_PPC_E500, causing mask_user_address_isel() to not be used on E500 hardware. Fix the check to use the correct name. | ||||
| CVE-2026-72003 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: wifi: brcmfmac: cyw: fix heap overflow on a short auth frame brcmf_notify_auth_frame_rx() takes the frame length from the firmware event and copies the frame body with the management header offset subtracted: u32 mgmt_frame_len = e->datalen - sizeof(struct brcmf_rx_mgmt_data); ... memcpy(&mgmt_frame->u, frame, mgmt_frame_len - offsetof(struct ieee80211_mgmt, u)); The only length check is e->datalen >= sizeof(*rxframe), so mgmt_frame_len can be anything from 0 up. offsetof(struct ieee80211_mgmt, u) is 24. When mgmt_frame_len is below that, the subtraction wraps as an unsigned value to a huge length. The memcpy then runs far past the kzalloc'd buffer. A malicious or malfunctioning AP can make the frame short during the external SAE auth exchange, so this is a remotely triggered heap overflow. Reject frames shorter than the management header offset before the copy. | ||||
| CVE-2026-72011 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: s390/diag: Add missing array_index_nospec() call to memtop_get_page_count() 'level' is user space controlled and used to read from an array. Add the missing array_index_nospec() call to prevent speculative execution. | ||||
| CVE-2026-72020 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 9.8 Critical |
| In the Linux kernel, the following vulnerability has been resolved: ipvs: reset full ip_vs_seq structs in ip_vs_conn_new Commit 9a05475cebdd ("ipvs: avoid kmem_cache_zalloc in ip_vs_conn_new") changed ip_vs_conn_new() to allocate an ip_vs_conn object with kmem_cache_alloc(). The function then initializes many fields explicitly, but only resets in_seq.delta and out_seq.delta in the two struct ip_vs_seq members. That leaves init_seq and previous_delta uninitialized. This is normally harmless while the corresponding IP_VS_CONN_F_IN_SEQ or IP_VS_CONN_F_OUT_SEQ flag is clear. For connections learned from a sync message, however, ip_vs_proc_conn() preserves those flags from IP_VS_CONN_F_BACKUP_MASK and passes opt=NULL when the message omits IPVS_OPT_SEQ_DATA. In that case the new connection can be hashed with SEQ flags set but with the rest of in_seq/out_seq still containing stale slab data. When a packet for such a connection is later handled by an IPVS application helper, vs_fix_seq() and vs_fix_ack_seq() use previous_delta and init_seq to rewrite TCP sequence numbers. A malformed sync message can therefore make forwarded packets carry stale slab bytes in their TCP seq/ack numbers, and can also corrupt the forwarded TCP flow. Reset both struct ip_vs_seq members completely before publishing the connection. This matches the existing "reset struct ip_vs_seq" comment and keeps the sequence-adjustment gates inactive unless valid sequence data is installed later. | ||||
| CVE-2026-72038 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: net: liquidio: fix BAR resource leak on PF number failure If cn23xx_get_pf_num() fails, the function returns without unmapping either BAR. Unmap both BARs before returning from the error path. Found by manual code review. | ||||
| CVE-2026-72039 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: bnx2x: fix potential memory leak in bnx2x_alloc_mem_bp() If the allocation of fp[i].tpa_info fails, the error path will not free the struct bnx2x_fastpath allocated earlier, as it is not linked to the bp structure yet. Fix that by linking it immediately after allocation. | ||||
| CVE-2026-72058 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: net: ixp4xx_hss: fix duplicate HDLC netdev allocation ixp4xx_hss_probe() allocates two HDLC netdevs. The first one is stored in ndev, initialized, and registered with register_hdlc_device(). The second one is stored in port->netdev and later used by the remove path for unregister_hdlc_device() and free_netdev(). This means that the registered netdev is not the same object that is unregistered and freed on remove. It also leaks the first allocation if the second alloc_hdlcdev() call fails, and the first allocation is not checked before ndev is used. Older code allocated the HDLC netdev only once and stored the same object in both the local variable and port->netdev. The buggy conversion split this into two alloc_hdlcdev() calls. A later rename changed the local variable name to ndev, but the underlying mismatch remained. Fix this by allocating the HDLC netdev only once and assigning the same object to port->netdev. | ||||
| CVE-2026-72095 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: dma-fence: Make dma_fence_dedup_array() robust against 0-count input dma_fence_dedup_array() returns 1 when called with num_fences == 0: the for-loop body never executes, j stays at 0, and the final `return ++j` yields 1. This contradicts both the kernel-doc ("Return: Number of unique fences remaining in the array") and the natural expectation that 0 input gives 0 output. The caller __dma_fence_unwrap_merge() bails out via the `if (count == 0 || count == 1)` fast path and so is save. But amdgpu_userq_wait_*() could reach the dedup call with a zero local count and dereference an uninitialized fence slot in the array. Make the contract match the documentation by returning 0 early. This also skips an unnecessary sort() call on an empty array. | ||||
| CVE-2026-50523 | 1 Microsoft | 1 Powershell | 2026-08-18 | 7.8 High |
| Improper neutralization of special elements used in a command ('command injection') in Microsoft PowerShell allows an authorized attacker to execute code locally. | ||||
| CVE-2026-16138 | 1 Progress | 1 Sharefile Storage Zones Controller | 2026-08-18 | 8 High |
| In Progress ShareFile Storage Zones Controller v5.12.5 and below versions, unsafe deserialization of untrusted file metadata can allow a user with write access to a Network share to execute arbitrary code on the Storage Zones Controller host. | ||||
| CVE-2026-16137 | 1 Progress | 1 Sharefile Storage Zones Controller | 2026-08-18 | 7.2 High |
| In Progress ShareFile Storage Zones Controller v5.12.5 and below, a party with valid zone credentials can perform path traversal using resumable upload initiation endpoint, allowing the party to write arbitrary content to any location writable by the application's service account. This may result in the execution of attacker-supplied code. | ||||
| CVE-2026-68455 | 1 Linux | 2 Kernel, Linux Kernel | 2026-08-18 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: liveupdate: validate session type before performing operation The sessions ioctls are not applicable to all session types. PRESERVE_FD is only applicable to outgoing sessions. RETRIEVE_FD and FINISH are only valid for incoming session. Calling a incoming ioctl on an outgoing session is invalid and can cause file handlers to run into unexpected errors. For example, a user can create a (outgoing) session, preserve a memfd, and then immediately do a retrieve without doing a kexec in between. This would result in memfd's retrieve handler to run. The handlers expects to be called from a post-kexec context, and will try to do a kho_restore_vmalloc() or kho_restore_folio() to try and restore memory. KHO catches this (thanks to KHO_PAGE_MAGIC) and returns an error, but since this is considered an internal error and KHO throws out a bunch of WARN()s. Associate a type with each ioctl op and validate the type in luo_session_ioctl() before dispatching the ioctl handler to make sure the op is being called for the right session type. | ||||
| CVE-2026-68457 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 9.1 Critical |
| In the Linux kernel, the following vulnerability has been resolved: ksmbd: use opener credentials for FSCTL mutations SET_SPARSE, SET_ZERO_DATA and SET_COMPRESSION operate on an open SMB handle but call VFS xattr, fallocate or fileattr helpers with the current ksmbd worker credentials. Those helpers can revalidate inode permissions, ownership and LSM policy independently of the SMB handle access mask. Run each operation with the credentials captured in the target file when the handle was opened. Keep credential handling local to these single-file FSCTLs rather than applying session credentials to the complete IOCTL handler, which also contains handle-less and multi-handle operations. | ||||
| CVE-2026-68461 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: device property: initialize the remaining fields of fwnode_handle in fwnode_init() If a firmware node is allocated on the stack (for instance: temporary software node whose life-time we control) or on the heap - but using a non-zeroing allocation function - and initialized using fwnode_init(), its secondary pointer will contain uninitialized memory which likely will be neither NULL nor IS_ERR() and so may end up being dereferenced (for example: in dev_to_swnode()). Set fwnode->secondary to NULL on initialization. While at it: initialize the remaining fields of struct fwnode_handle too just to be sure. [ Fix typo in commit message. - Danilo ] | ||||
| CVE-2026-68465 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: mmc: sdhci-esdhc-imx: fix esdhc_change_pinstate() to allow default state restore esdhc_change_pinstate() checks for pins_100mhz and pins_200mhz at the top of the function and returns -EINVAL if either is not defined. This prevents the default case from ever being reached, which means devices with a sleep pinctrl state but without high-speed pin states (100mhz/ 200mhz) can never restore their default pin configuration. Move the IS_ERR checks for pins_100mhz and pins_200mhz into their respective switch cases. | ||||
| CVE-2026-68478 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: memstick: ms_block: reject a card that reports too many blocks msb_ftl_initialize() computes the zone count from the card block count with no bound: msb->zone_count = msb->block_count / MS_BLOCKS_IN_ZONE; ... for (i = 0; i < msb->zone_count; i++) msb->free_block_count[i] = MS_BLOCKS_IN_ZONE; msb->block_count is a card value. msb_read_boot_blocks() reads number_of_blocks from the card boot page and byte swaps it. free_block_count is a fixed int[MS_MAX_ZONES]. MS_MAX_ZONES is 16, so the valid indices are 0 to 15. The init loop above indexes it by zone_count. msb_mark_block_used() and msb_mark_block_unused() index it by pba / MS_BLOCKS_IN_ZONE, for pba up to block_count - 1. A card may report up to 65535 blocks. A block_count above 8192 (MS_MAX_ZONES * MS_BLOCKS_IN_ZONE) lets the pba index reach 16. That writes past free_block_count[] and corrupts struct msb_data. A larger count runs the init loop past the end too. A real Memory Stick has at most 16 zones. So it has at most 8192 blocks. msb_ftl_initialize() now rejects a card that reports more than MS_MAX_ZONES * MS_BLOCKS_IN_ZONE blocks. | ||||
| CVE-2026-68479 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btrtl: validate firmware patch bounds rtlbt_parse_firmware() copies patch_length - 4 bytes before appending the firmware version. A malformed firmware patch shorter than the version field can make this subtraction underflow and turn the copy into an oversized read and write during Bluetooth setup. The existing patch_offset + patch_length check can also wrap on 32-bit architectures. Validate the patch length and range without arithmetic overflow before allocating or copying the patch. | ||||
| CVE-2026-72004 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: fix memory leak in ieee80211_register_hw() If kmemdup() fails while copying supported band structures, the error path jumps to fail_rate. This skips rate_control_deinitialize() and leaks the initialized local->rate_ctrl. Fix this by adding a fail_band label that shares the rate-control cleanup path before falling through to the remaining teardown. The bug was first flagged by an experimental analysis tool we are developing for kernel memory-management bugs while analyzing v6.13-rc1. The tool is still under development and is not yet publicly available. Manual inspection confirms that the bug is still present in v7.1-rc7. An x86_64 allyesconfig build showed no new warnings. As we do not have a suitable mac80211 device/driver combination to test with, no runtime testing was able to be performed. | ||||
| CVE-2026-72007 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: pmdomain: imx: Fix i.MX8MP VC8000E power up sequence Per errata[1]: ERR050531: VPU_NOC power down handshake may hang during VC8000E/VPUMIX power up/down cycling. Description: VC8000E reset de-assertion edge and AXI clock may have a timing issue. Workaround: Set bit2 (vc8000e_clk_en) of BLK_CLK_EN_CSR to 0 to gate off both AXI clock and VC8000E clock sent to VC8000E and AXI clock sent to VPU_NOC m_v_2 interface during VC8000E power up(VC8000E reset is de-asserted by HW) Add a bool variable is_errata_err050531 in 'struct imx8m_blk_ctrl_domain_data' to represent whether the workaround is needed. If is_errata_err050531 is true, first clear the clk before powering up gpc, then enable the clk after powering up gpc. [1] https://www.nxp.com/webapp/Download?colCode=IMX8MP_1P33A | ||||
| CVE-2026-72008 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: pmdomain: mediatek: Fix possible nullptr KP in HWV cleanup/on-check Should probe fail for HW_VOTER type power domains, this driver was unconditionally trying to perform cleanup for DIRECT_CTL domains, but only after checking if the target domain is powered on... with the DIRECT_CTL scpsys_domain_is_on() code again. And there's more: the scpsys_domain_is_on() function is also being unconditionally used in the probe path, for any power domain that has flag MTK_SCPD_KEEP_DEFAULT_OFF! This bug was never experienced by anyone because the HWV domains never failed probe, and because none of those is declared with the aforementioned flag - but it's still something critical. In order to fix this, add a check for MTCMOS Type and, based on that, call the correct functions for an "is on" check, and also do the same for the cleanup path, calling the correct functions for the "power off" action. For the latter, since there's a call to pm_genpd_remove() right before calling power_off, be cautious and add a variation of the power off functions (with a _internal suffix) for those to get a pointer to scpsys_domain instead of one to generic_pm_domain as, even if that's still working, this is way too much fragile and would break at some point. | ||||
