EUVD-2026-32483

In the Linux kernel, the following vulnerability has been resolved: fs: afs: revert mmapprepare change Partially reverts commit 9d5403b1036c "fs: convert most other genericfilemmap users to .mmapprepare". This is because the .mmap invocation establishes a refcount, but .mmapprepare is called at a...

CVE-2026-46063

The CVE-2026-46063 issue affects the Linux kernel with x86 shadow stack (shstk) handling of sigreturn. Root cause: during a shadow-stack sigframe read, the kernel previously held the mmap lock while verifying VMA flags to distinguish shadow stack memory. A page fault during this read could trigge...

CVE-2026-45986

The CVE-2026-45986 issue affects the Linux kernel crypto/ccree path, specifically a memory leak in cc_mac_digest. The root cause is a path where cc_map_hash_request_final() failures could leave memory unreleased; the fix adds cc_unmap_result() to prevent leaks. The vulnerability is locally exploi...

CVE-2026-45967 bpf: Return proper address for non-zero offsets in insn array

In the Linux kernel, the following vulnerability has been resolved: bpf: Return proper address for non-zero offsets in insn array The mapdirectvalueaddr function of the instruction array map incorrectly adds offset to the resulting address. This is a bug, because later the resolvepseudoldimm64...

CVE-2026-45927

In CVE-2026-45927, the Linux kernel BPF path bpf_map_get_info_by_fd caches the map hash regardless of the map’s frozen state, enabling a TOCTOU where a loader could verify a stale hash before freezing contents. The fix returns -EPERM if the map is not frozen when the hash is requested, ensuring t...

CVE-2026-45927 bpf: Require frozen map for calculating map hash

In the Linux kernel, the following vulnerability has been resolved: bpf: Require frozen map for calculating map hash Currently, bpfmapgetinfobyfd calculates and caches the hash of the map regardless of the map's frozen state. This leads to a TOCTOU bug where userspace can call BPFOBJGETINFOBYFD t...

CVE-2026-45908

The CVE affects the Linux kernel’s accel/amdxdna path. The amdxdna_ubuf_map() function allocates memory for sg and internal sg table structures but fails to free them if subsequent operations (sg_alloc_table_from_pages or dma_map_sgtable) fail, causing a memory leak. The entry notes that this vul...

CVE-2026-45886

CVE-2026-45886 : Linux kernel fix for bpf_xdp_store_bytes argument type error when writing to read-only maps. The verifier flagged a MEM_WRITE on R3 (PTR_TO_MAP_VALUE from a read-only map) due to ARG_PTR_TO_UNINIT_MEM; the third argument’s type did not match bpf_skb_store_bytes. The patch aligns ...

CVE-2026-45886 bpf: Fix bpf_xdp_store_bytes proto for read-only arg

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix bpfxdpstorebytes proto for read-only arg While making some maps in Cilium read-only from the BPF side, we noticed that the bpfxdpstorebytes proto is incorrect. In particular, the verifier was throwing the following error...

CVE-2026-45880

In the Linux kernel, the following vulnerability has been resolved: PCI/P2PDMA: Release per-CPU pgmap ref when vminsertpage fails When vminsertpage fails in p2pmemallocmmap, p2pmemallocmmap doesn't invoke percpurefput to free the per-CPU ref of pgmap acquired after genpoolallocowner, and...

CVE-2025-71304

The CVE-2025-71304 entry describes a Linux kernel Smack issue where /smack/doi could accept values that were previously written, causing decommissioned DOIs to linger and the default domain map to be unavailable. This behavior can disable networking for non-ambient labels because existing CIPSO/D...

CVE-2025-71304 smack: /smack/doi: accept previously used values

In the Linux kernel, the following vulnerability has been resolved: smack: /smack/doi: accept previously used values Writing to /smack/doi a value that has ever been written there in the past disables networking for non-ambient labels. E.g. cat /smack/doi 3 netlabelctl -p cipso list Configured...
