https://notcve.org/view.php?id=CVE-2025-39965
13 Oct 2025 — In the Linux kernel, the following vulnerability has been resolved: xfrm: xfrm_alloc_spi shouldn't use 0 as SPI x->id.spi == 0 means "no SPI assigned", but since commit 94f39804d891 ("xfrm: Duplicate SPI Handling"), we now create states and add them to the byspi list with this value. __xfrm_state_delete doesn't remove those states from the byspi list, since they shouldn't be there, and this shows up as a UAF the next time we go through the byspi list. In the Linux kernel, the following vulnerability has bee... • https://git.kernel.org/stable/c/3d8090bb53424432fa788fe9a49e8ceca74f0544 •

CVE-2025-39964 – crypto: af_alg - Disallow concurrent writes in af_alg_sendmsg

13 Oct 2025 — In the Linux kernel, the following vulnerability has been resolved: crypto: af_alg - Disallow concurrent writes in af_alg_sendmsg Issuing two writes to the same af_alg socket is bogus as the data will be interleaved in an unpredictable fashion. Furthermore, concurrent writes may create inconsistencies in the internal socket state. Disallow this by adding a new ctx->write field that indiciates exclusive ownership for writing.

CVE-2025-39961 – iommu/amd/pgtbl: Fix possible race while increase page table level

09 Oct 2025 — In the Linux kernel, the following vulnerability has been resolved: iommu/amd/pgtbl: Fix possible race while increase page table level The AMD IOMMU host page table implementation supports dynamic page table levels (up to 6 levels), starting with a 3-level configuration that expands based on IOVA address. The kernel maintains a root pointer and current page table level to enable proper page table walks in alloc_pte()/fetch_pte() operations. The IOMMU IOVA allocator initially starts with 32-bit address and o... • https://git.kernel.org/stable/c/754265bcab78a9014f0f99cd35e0d610fcd7dfa7 •

09 Oct 2025 — In the Linux kernel, the following vulnerability has been resolved: iommu/s390: Make attach succeed when the device was surprise removed When a PCI device is removed with surprise hotplug, there may still be attempts to attach the device to the default domain as part of tear down via (__iommu_release_dma_ownership()), or because the removal happens during probe (__iommu_probe_device()). In both cases zpci_register_ioat() fails with a cc value indicating that the device handle is invalid.

CVE-2025-39957 – wifi: mac80211: increase scan_ies_len for S1G

09 Oct 2025 — In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: increase scan_ies_len for S1G Currently the S1G capability element is not taken into account for the scan_ies_len, which leads to a buffer length validation failure in ieee80211_prep_hw_scan() and subsequent WARN in __ieee80211_start_scan(). This prevents hw scanning from functioning. To fix ensure we accommodate for the S1G capability length.

CVE-2023-53684 – xfrm: Zero padding when dumping algos and encap
https://notcve.org/view.php?id=CVE-2023-53684
07 Oct 2025 — In the Linux kernel, the following vulnerability has been resolved: xfrm: Zero padding when dumping algos and encap When copying data to user-space we should ensure that only valid data is copied over. Padding in structures may be filled with random (possibly sensitve) data and should never be given directly to user-space. This patch fixes the copying of xfrm algorithms and the encap template in xfrm_user so that padding is zeroed. In the Linux kernel, the following vulnerability has been resolved: xfrm: Ze... • https://git.kernel.org/stable/c/0725daaa9a879388ed312110f62dbd5ea2d75f8f •
