| CVE-2026-63981 | 1 Linux | 1 Linux Kernel | 2026-07-26 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: net/sched: act_mirred: Fix blockcast recursion bypass leading to stack overflow tcf_mirred_act() checks sched_mirred_nest against MIRRED_NEST_LIMIT (4) to prevent deep recursion. However, when the action uses blockcast (tcfm_blockid != 0), the function returns at the tcf_blockcast() call BEFORE reaching the counter increment. As a result, the recursion counter never advances and the limit check is entirely bypassed. When two devices share a TC egress block with a mirred blockcast rule, a packet egressing on device A is mirrored to device B via blockcast; device B's egress TC re-enters tcf_mirred_act() via blockcast and mirrors back to A, creating an unbounded recursion loop: tcf_mirred_act -> tcf_blockcast -> tcf_mirred_to_dev -> dev_queue_xmit -> sch_handle_egress -> tcf_classify -> tcf_mirred_act -> (repeat) This recursion continues until the kernel stack overflows. The bug is reachable from an unprivileged user via unshare(CLONE_NEWUSER | CLONE_NEWNET): user namespaces grant CAP_NET_ADMIN in the new network namespace, which is sufficient to create dummy devices, attach clsact qdiscs with shared blocks, and install mirred blockcast filters. BUG: TASK stack guard page was hit at ffffc90000b7fff8 Oops: stack guard page: 0000 [#1] SMP KASAN NOPTI CPU: 2 UID: 1000 PID: 169 Comm: poc Not tainted 7.0.0-rc7-next-20260410 RIP: 0010:xas_find+0x17/0x480 Call Trace: xa_find+0x17b/0x1d0 tcf_mirred_act+0x640/0x1060 tcf_action_exec+0x400/0x530 basic_classify+0x128/0x1d0 tcf_classify+0xd83/0x1150 tc_run+0x328/0x620 __dev_queue_xmit+0x797/0x3100 tcf_mirred_to_dev+0x7b1/0xf70 tcf_mirred_act+0x68a/0x1060 [repeating ~30+ times until stack overflow] Kernel panic - not syncing: Fatal exception in interrupt Fix this by incrementing sched_mirred_nest before calling tcf_blockcast() and decrementing it on return, mirroring the non-blockcast path. This ensures subsequent recursive entries see the updated counter and are correctly limited by MIRRED_NEST_LIMIT. | ||||
| CVE-2026-63987 | 1 Linux | 1 Linux Kernel | 2026-07-26 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: ethtool: coalesce: cap profile updates at NET_DIM_PARAMS_NUM_PROFILES ethnl_update_profile() walks the ETHTOOL_A_PROFILE_IRQ_MODERATION nest list with an index 'i' and writes new_profile[i++] without bounding i. The destination is kmemdup()'d at NET_DIM_PARAMS_NUM_PROFILES entries (5), but the Netlink nest count is entirely user-controlled. Netlink policies do not have support for constraining the number of nested entries (or number of multi-attr entries). | ||||
| CVE-2026-63995 | 1 Linux | 1 Linux Kernel | 2026-07-26 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: ethtool: cmis: validate start_cmd_payload_size from module The CMIS firmware update code reads start_cmd_payload_size from the module's FW Management Features CDB reply and uses it directly as the byte count for memcpy. The destination buffer is 112 bytes (ETHTOOL_CMIS_CDB_LPL_MAX_PL_LENGTH - 8). So a malicious module (or corrupted response) can cause a OOB write later on in cmis_fw_update_start_download(). Let's error out. If modules that expect longer LPL writes actually exist we should revisit. struct cmis_cdb_start_fw_download_pl's definition has to move, no change there. | ||||
| CVE-2026-64003 | 1 Linux | 1 Linux Kernel | 2026-07-26 | 7.5 High |
| In the Linux kernel, the following vulnerability has been resolved: scsi: core: Run queues for all non-SDEV_DEL devices from scsi_run_host_queues While a SCSI host is in a recovery state, scsi_mq_requeue_cmd() will not set the requeue list for a requeued command to be kicked in the future. The expectation is a call to scsi_run_host_queues() will kick all SCSI devices once the recovery state is cleared. However, scsi_run_host_queues() uses shost_for_each_device() which uses scsi_device_get() and so will ignore devices in a partially removed state like SDEV_CANCEL. But these devices may also have requeued requests, leaving their requests stuck from not being kicked and causing the removal process of the device to hang. scsi_run_host_queues() needs to run against more devices than the macro shost_for_each_device() allows. Instead of using the too limiting scsi_device_get() state checks, only ignore devices in SDEV_DEL state or when unable to acquire a reference. Attempt to run the queues for all other devices when scsi_run_host_queues() is called. | ||||
| CVE-2026-64013 | 1 Linux | 1 Linux Kernel | 2026-07-26 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: ACPI: button: Fix ACPI GPE handler leak during removal Commit a7e23ec17fee ("ACPI: button: Install notifier for system events as well") changed the ACPI notify handler type for ACPI buttons to ACPI_ALL_NOTIFY, but it forgot to update acpi_button_remove() to reflect that change. This leads to leaking the notify handler past driver removal, which may cause a kernel crash to occur if ACPI notify on the given device is triggered after removing the driver, and causes a subsequent probe of the given device with the same driver to fail. Address this by updating the acpi_remove_notify_handler() call in acpi_button_remove() as appropriate. | ||||
| CVE-2026-64018 | 1 Linux | 1 Linux Kernel | 2026-07-26 | 9.3 Critical |
| In the Linux kernel, the following vulnerability has been resolved: net: mana: validate rx_req_idx to prevent out-of-bounds array access In mana_hwc_rx_event_handler(), rx_req_idx is derived from sge->address in DMA-coherent memory. In Confidential VMs (SEV-SNP/TDX), this memory is shared unencrypted and HW can modify WQE contents at any time. No bounds check exists on rx_req_idx, which can lead to an out-of-bounds access into reqs[]. Add bounds check on rx_req_idx in mana_hwc_rx_event_handler() before using it to index the reqs[] array. | ||||
| CVE-2026-64036 | 1 Linux | 1 Linux Kernel | 2026-07-26 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: cgroup/rstat: validate cpu before css_rstat_cpu() access css_rstat_updated() is exposed as a BPF kfunc and accepts a caller-provided cpu argument. The function uses cpu for per-cpu rstat lookups without checking whether it refers to a valid possible CPU. A BPF iter/cgroup program with CAP_BPF and CAP_PERFMON can pass an invalid cpu value. On an unfixed UBSCAN_BOUNDS test kernel, cpu == 0x7fffffff triggers: UBSAN: array-index-out-of-bounds in kernel/cgroup/rstat.c:31:9 index 2147483647 is out of range for type 'long unsigned int [64]' Call Trace: css_rstat_updated bpf_iter_run_prog cgroup_iter_seq_show bpf_seq_read Add cpu validation to the BPF-facing css_rstat_updated() kfunc and move the common implementation to __css_rstat_updated() for in-kernel callers. | ||||

| CVE-2026-64509 | 1 Linux | 1 Linux Kernel | 2026-07-26 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: rust: block: fix GenDisk cleanup paths GenDiskBuilder::build() still has fallible work after __blk_mq_alloc_disk(), but its error path only recovers the foreign queue data. That leaks the temporary gendisk and request_queue until later teardown. If the caller moved the last Arc<TagSet<T>> into build(), the leaked queue can retain blk-mq state after the tag set is dropped. Fix the pre-registration failure path by dropping the temporary gendisk reference with put_disk() before recovering queue_data, so disk_release() can tear down the owned queue. Also pair GenDisk::drop() with put_disk() after del_gendisk(). Once a Rust GenDisk has been added with device_add_disk(), del_gendisk() only unregisters it; the final gendisk reference still has to be dropped to complete the release path. | ||||
| CVE-2026-64498 | 1 Linux | 1 Linux Kernel | 2026-07-26 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: iio: buffer: hw-consumer: free scan_mask on buffer release The scan_mask lifetime changed in commit 9a2e1233d38c ("iio: buffer: hw-consumer: remove redundant scan_mask flexible array"). Before that change, the scan mask storage was embedded in struct hw_consumer_buffer, so iio_hw_buf_release() could free the whole allocation with a single kfree(hw_buf). That commit moved the scan mask to a separate bitmap_zalloc() allocation stored in buffer.scan_mask, but left iio_hw_buf_release() unchanged. Free the scan mask in iio_hw_buf_release() before freeing the buffer wrapper. | ||||
| CVE-2026-64464 | 1 Linux | 1 Linux Kernel | 2026-07-25 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: xhci: sideband: fix ring sg table pages leak xhci_ring_to_sgtable() allocates a temporary pages array and uses it to build the returned sg_table with sg_alloc_table_from_pages(). The error paths free the pages array, but the success path returns the sg_table without freeing it. This leaks the temporary array every time a sideband client gets an endpoint or event ring buffer. Free the pages array after sg_alloc_table_from_pages() succeeds. The returned sg_table has its own scatterlist entries and does not depend on the temporary array after construction. | ||||
| CVE-2026-15767 | 2 Google, Microsoft | 2 Chrome, Windows | 2026-07-25 | 8.8 High |

| CVE-2026-63929 | 1 Linux | 1 Linux Kernel | 2026-07-25 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: iio: buffer: Fix DMA fence leak in iio_buffer_enqueue_dmabuf() iio_buffer_enqueue_dmabuf() allocates a struct iio_dma_fence (104 bytes, kmalloc-128) via kmalloc_obj()+dma_fence_init(), which sets the initial kref to 1. It then calls dma_resv_add_fence() which takes a second reference (kref=2), and stores a raw pointer in block->fence. On the success path the function returns without calling dma_fence_put() to release the initial reference, so every buffer enqueue permanently leaks one kmalloc-128 allocation. The iio_buffer_cleanup() work item only releases the temporary reference taken during completion signalling by iio_buffer_signal_dmabuf_done(); the initial reference from dma_fence_init() is never released. With four iio_rwdev instances at 240kHz and 512 samples per buffer, this produces ~1875 kmalloc-128 allocations per second matching the observed slab growth exactly. A test with ftrace confirmed that the dma_fence_destroy event was never triggered. Fix by calling dma_fence_put() after dma_resv_add_fence(), transferring ownership of the fence to the DMA reservation object. The DMA fence then gets properly discarded after being signalled. | ||||
| CVE-2026-66010 | 1 Cure53 | 1 Dompurify | 2026-07-24 | 6.1 Medium |
| DOMPurify before 3.4.12 fails to execute afterSanitizeElements hook for custom elements allowed via CUSTOM_ELEMENT_HANDLING.tagNameCheck, allowing attributes to bypass application security policies. Attackers can preserve sensitive attributes on custom elements that later re-inject them into innerHTML sinks, creating second-order XSS gadgets. | ||||
| CVE-2026-45813 | 1 Apache | 1 Nimble | 2026-07-24 | 8.8 High |
| Out-of-bounds Write, Integer Underflow (Wrap or Wraparound) vulnerability in Apache NimBLE BASS service. Improper validation when parsing BASS service "Add Source" and "Modify Source" operation PDU could results in stack buffer overflow or arbitrary out-of-bound read. This can be triggered by nearby devices over Bluetooth connection, however pairing is required prior to accessing BASS service, which depending on device configuration may or may not require user action. This issue affects Apache NimBLE: through 1.9.0. Users are recommended to upgrade to version 1.10.0, which fixes the issue. | ||||
