| In the Linux kernel, the following vulnerability has been resolved: crypto: ccp - Treat zero-length cert chain as query for blob lengths When handling a PDH export, treat a zero-length userspace cert chain buffer as a request to query the length of the relevant blobs. Failure to account for the zero-length buffer trips a BUG_ON() when running with CONFIG_DEBUG_VIRTUAL=y due to trying to get the physical address of the ZERO_SIZE_PTR (returned by kzalloc() on the bogus allocation). kernel BUG at arch/x86/mm/physaddr.c:28 !

| CVE-2026-80654 | 1 Linux | 1 Linux Kernel | 2026-08-28 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: soc: xilinx: Shutdown and free rx mailbox channel A mbox rx channel is requested using mbox_request_channel_byname() in probe. In remove callback, the rx mailbox channel is cleaned up when the rx_chan is NULL due to incorrect condition check. The mailbox channel is not shutdown and it can receive messages even after the device removal. This leads to use after free. Also the channel resources are not freed. Fix this by checking the rx_chan correctly. | ||||

| In Zimbra Collaboration (ZCS) before 10.1.17, weak cryptographic key generation vulnerability exists in the OnlyOffice integration. The zimbraDocumentEditingJwtSecret is generated using an insecure random number generator, resulting in insufficient entropy. An attacker who obtains a JWT signed with the generated secret may be able to recover the JWT signing secret through offline brute-force, potentially enabling JWT forgery. | ||||

| CVE-2026-80689 | 1 Linux | 1 Linux Kernel | 2026-08-28 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: tracing/mmiotrace: Add NULL check for mmio_trace_array in logging functions mmio_trace_rw() and mmio_trace_mapping() retrieve mmio_trace_array into tr and pass it to __trace_mmiotrace_rw() and __trace_mmiotrace_map(). If these functions are invoked while mmio_trace_array is NULL (e.g. before initialization or after disabled), accessing tr->array_buffer.buffer will result in a NULL pointer dereference crash. Fix this by adding an explicit NULL check for tr at the beginning of __trace_mmiotrace_rw() and __trace_mmiotrace_map(). | ||||
| CVE-2026-53362 | 1 Linux | 1 Linux Kernel | 2026-08-28 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: ipv6: account for fraggap on the paged allocation path In __ip6_append_data(), when the paged-allocation branch is taken (MSG_MORE / NETIF_F_SG / large fraglen), alloclen and pagedlen are computed as alloclen = fragheaderlen + transhdrlen; pagedlen = datalen - transhdrlen; datalen already includes fraggap (datalen = length + fraggap). When fraggap is non-zero, this is not the first skb and transhdrlen is zero. The fraggap bytes carried over from the previous skb are copied just past the fragment headers in the new skb's linear area. The linear area is therefore undersized by fraggap bytes while pagedlen is overstated by the same amount, and the copy writes past skb->end into the trailing skb_shared_info. An unprivileged user can trigger this via a UDPv6 socket using MSG_MORE together with MSG_SPLICE_PAGES. The bad accounting was introduced by commit 773ba4fe9104 ("ipv6: avoid partial copy for zc"). Before commit ce650a166335 ("udp6: Fix __ip6_append_data()'s handling of MSG_SPLICE_PAGES"), the negative copy value caused -EINVAL to be returned. That later commit allowed MSG_SPLICE_PAGES to proceed in this case, making the corruption triggerable. The non-paged branch sets alloclen to fraglen, which already accounts for fraggap because datalen does. Bring the paged branch in line by adding fraggap to alloclen and subtracting it from pagedlen. After this adjustment, copy no longer collapses to -fraggap on the paged path, so remove the stale comment describing that old arithmetic. Since a negative copy is no longer expected for a valid MSG_SPLICE_PAGES case, remove the MSG_SPLICE_PAGES exception from the negative copy check. | ||||

| In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7996: Fix NULL pointer dereference in mt7996_init_tx_queues() When MT76_NPU and CONFIG_NET_MEDIATEK_SOC_WED are enabled and mt76 detects properly the Airoha NPU SoC, mt7996_init_tx_queues() will dereference a NULL WED pointer. Fix the issue by always passing the WED pointer from mt7996_dma_init(). | ||||
| CVE-2026-80655 | 1 Linux | 1 Linux Kernel | 2026-08-28 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: soc: xilinx: Fix race condition in event registration The zynqmp_power driver registers handlers for suspend and subsystem restart events using register_event(). However, the work structures (zynqmp_pm_init_suspend_work and zynqmp_pm_init_restart_work) used by these handlers were allocated and initialized after the registration call. This created a race window where, if the firmware triggered an event immediately after registration but before allocation, the callback (suspend_event_callback or subsystem_restart_event_callback) would dereference a NULL pointer in work_pending(), leading to a crash. Fix this by allocating and initializing the work structures before registering the events. | ||||

| In the Linux kernel, the following vulnerability has been resolved: Input: ims-pcu - add response length checks The driver processes response data from device buffers without verifying that the device actually sent enough data. This can lead to out-of-bounds reads or processing stale data. Add checks for the expected response length before accessing the buffers. | ||||
| CVE-2026-80651 | 1 Linux | 1 Linux Kernel | 2026-08-28 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: crypto: ccp/sev-dev-tsm - bail out early when pdev->bus is NULL dsm_create() initially checks pdev->bus when computing segment_id: u8 segment_id = pdev->bus ? pci_domain_nr(pdev->bus) : 0; But the next two lines unconditionally dereference pdev->bus via pcie_find_root_port() and especially pci_dev_id(pdev), which expands to PCI_DEVID(dev->bus->number, dev->devfn). If pdev->bus is in fact NULL, segment_id is initialised to 0 but the very next statement crashes the kernel. smatch flags this: drivers/crypto/ccp/sev-dev-tsm.c:253 dsm_create() error: we previously assumed 'pdev->bus' could be null (see line 251) Make the NULL handling consistent: if pdev->bus is NULL the device has no PCI context to work with and SEV TIO setup cannot proceed, so return -ENODEV before any of the bus-dependent lookups. The remaining initialisation now runs only on the path where pdev->bus is known to be valid. No change for callers where pdev->bus is non-NULL, which is the only case where dsm_create() did meaningful work before this change. | ||||

| In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: Guard management mailbox channel cleanup against NULL pointer The management mailbox channel cleanup helpers can be called from error handling paths when mgmt_chann has already been destroyed. Add NULL checks to xdna_mailbox_free_channel() and xdna_mailbox_stop_channel() so the cleanup path safely returns instead of dereferencing a NULL mailbox channel pointer. | ||||

| CVE-2026-80620 | 1 Linux | 1 Linux Kernel | 2026-08-28 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: Revert "PCI/MSI: Unmap MSI-X region on error" This reverts commit 1a8d4c6ecb4c81261bcdf13556abd4a958eca202. Commit 1a8d4c6ecb4c ("PCI/MSI: Unmap MSI-X region on error") added an iounmap(dev->msix_base) on the error path of msix_capability_init() to release the MSI-X region when msix_setup_interrupts() fails. When msix_setup_interrupts() fails, the call chain is: msix_setup_interrupts() -> __msix_setup_interrupts() struct pci_dev *dev __free(free_msi_irqs) = __dev; ... return ret; // __free cleanup fires on error The __free(free_msi_irqs) cleanup calls pci_free_msi_irqs(), which already handles the unmap: void pci_free_msi_irqs(struct pci_dev *dev) { pci_msi_teardown_msi_irqs(dev); if (dev->msix_base) { iounmap(dev->msix_base); // already unmapped here dev->msix_base = NULL; // and set to NULL } } So dev->msix_base is unmapped and set to NULL before msix_setup_interrupts() returns to msix_capability_init(). The "goto out_unmap" introduced by commit 1a8d4c6ecb4c ("PCI/MSI: Unmap MSI-X region on error") then calls iounmap() a second time on a NULL pointer. This was reproduced on Intel Emerald Rapids (192 CPUs) while running tools/testing/selftests/kexec/test_kexec_jump.sh: WARNING: CPU#44 at iounmap+0x2a/0xe0 RIP: 0010:iounmap+0x2a/0xe0 RDI: 0000000000000000 Call Trace: msix_capability_init+0x317/0x3f0 __pci_enable_msix_range+0x21d/0x2c0 pci_alloc_irq_vectors_affinity+0xa9/0x130 nvme_setup_io_queues+0x2a8/0x420 [nvme] nvme_reset_work+0x151/0x340 [nvme] ... RDI=0 confirms iounmap() is called with NULL. Restore the original "goto out_disable" and leave the unmap to the existing __free(free_msi_irqs) cleanup. | ||||
| CVE-2026-75758 | 1 Elixir-lang | 1 Elixir | 2026-08-28 | N/A |
| Uncontrolled Recursion vulnerability in the Elixir standard library allows an attacker who controls a list passed to inspect/1, List.to_string/1, or List.to_charlist/1 to exhaust a BEAM node's memory. Inspect.List's charlist branch in lib/elixir/lib/inspect.ex classifies a list as a charlist using List.ascii_printable?/2, which examines only the first :printable_limit (4096 by default) elements, and then calls IO.chardata_to_string/1 on the whole term. A list whose printable prefix exceeds that limit but which contains a later element that is not a code point (an atom, an out-of-range integer, or an improper tail) is therefore mis-classified, and the conversion raises ArgumentError. That conversion runs inside List.to_string/1, whose rescue clause builds its message by interpolating inspect(list), which re-enters the same branch and raises again. The nested inspection is an argument to raise, so the recursion is not in tail position and every level is retained: the process stack grows monotonically while each cycle re-walks the list, until the process is killed by max_heap_size or, by default, the node runs out of memory. List.to_charlist/1 has the same rescue shape. Below the printable limit the inner inspect/1 sees the invalid element within its counter and renders the list in ordinary bracket form, so a single ArgumentError is raised and no recursion occurs. This issue affects elixir: from 1.15.0-rc.0 before 1.18.5, from 1.19.0-rc.0 before 1.19.6, and from 1.20.0-rc.0 before 1.20.4. | ||||

| gitoxide versions from 0.25.4 contain an HTTP credential leak vulnerability in the curl-based transport backend where credentials are sent to attacker-controlled servers after HTTP redirects. The vulnerability occurs because credential validation checks the original URL instead of the effective URL after redirect, allowing attackers to steal authentication tokens through cross-domain redirects or HTTPS-to-HTTP downgrades. | ||||
