Vulnerability from cvelistv5
Published

Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
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.

Although the dangling byspi entry can subsequently be dereferenced by a received ESP/AH packet, creating the SPI-0 state requires the local netlink path.\\nAC:L - The attacker deterministically triggers the bug by requesting min=max=0, which verify_spi_info() accepts, then deleting the state via DELSA/FLUSHSA; there is no race, no memory-layout dependency, and no non-default config beyond ubiquitous CONFIG_XFRM_USER.\\nPR:L - xfrm_user_rcv_msg() gates on netlink_net_capable(skb, CAP_NET_ADMIN), which is evaluated against the net namespace\u0027s user_ns, so any unprivileged user obtains it via \\\"unshare -Urn\\\". This is Low, not High.\\nUI:N - The full sequence \\u2014 allocate SPI 0, delete the state, re-walk the byspi hash \\u2014 is performed entirely by the attacker\u0027s own process with no victim action required.\\nS:U - The freed xfrm_state and the corrupted hash list both live in the kernel\u0027s own security authority; this is standard kernel memory corruption with no VM, IOMMU, or hypervisor boundary crossed.\\nC:H - The dangling xfrm_state remains in a global RCU hash and is read back and returned as a live SA, so a reclaimed object leaks adjacent heap contents and crypto/key state, and the UAF can be escalated into an arbitrary kernel read primitive.\\nI:H - Walkers perform refcount_inc_not_zero on the freed object (a write to freed memory) and then use it as a live SA whose type/mode function-pointer fields the attacker can control by re-spraying the xfrm_state slab, yielding control-flow hijack and arbitrary write.\\nA:H - Dereferencing the freed state during byspi traversal, hash resize, or netns teardown (WARN_ON(!hlist_empty())) reliably produces a KASAN-detected use-after-free, list corruption, and kernel panic.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"3d8090bb53424432fa788fe9a49e8ceca74f0544\", \"lessThan\": \"0baf92d0b1590b903c1f4ead75e61715e50e8146\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"2fc5b54368a1bf1d2d74b4d3b8eea5309a653e38\", \"lessThan\": \"9fcedabaae0096f712bbb4ccca6a8538af1cd1c8\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"29e9158f91f99057dbd35db5e8674d93b38549fe\", \"lessThan\": \"a78e55776522373c446f18d5002a8de4b09e6bf7\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"94f39804d891cffe4ce17737d295f3b195bc7299\", \"lessThan\": \"cd8ae32e4e4652db55bce6b9c79267d8946765a9\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"c67d4e7a8f90fb6361ca89d4d5c9a28f4e935e47\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"6.15.11\", \"lessThan\": \"6.16\", \"versionType\": \"semver\"}], \"programFiles\": [\"net/xfrm/xfrm_state.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"6.6.103\", \"lessThan\": \"6.6.109\", \"versionType\": \"semver\"}, {\"status\": \"affected\", \"version\": \"6.12.43\", \"lessThan\": \"6.12.50\", \"versionType\": \"semver\"}, {\"status\": \"affected\", \"version\": \"6.16.2\", \"lessThan\": \"6.16.10\", \"versionType\": \"semver\"}], \"programFiles\": [\"net/xfrm/xfrm_state.c\"], \"defaultStatus\": \"unaffected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/0baf92d0b1590b903c1f4ead75e61715e50e8146\"}, {\"url\": \"https://git.kernel.org/stable/c/9fcedabaae0096f712bbb4ccca6a8538af1cd1c8\"}, {\"url\": \"https://git.kernel.org/stable/c/a78e55776522373c446f18d5002a8de4b09e6bf7\"}, {\"url\": \"https://git.kernel.org/stable/c/cd8ae32e4e4652db55bce6b9c79267d8946765a9\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nxfrm: xfrm_alloc_spi shouldn\u0027t use 0 as SPI\\n\\nx-\u003eid.spi == 0 means \\\"no SPI assigned\\\", but since commit\\n94f39804d891 (\\\"xfrm: Duplicate SPI Handling\\\"), we now create states\\nand add them to the byspi list with this value.\\n\\n__xfrm_state_delete doesn\u0027t remove those states from the byspi list,\\nsince they shouldn\u0027t be there, and this shows up as a UAF the next\\ntime we go through the byspi list.\"}], \"cpeApplicability\": [{\"nodes\": [{\"negate\": false, \"cpeMatch\": [{\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.6.109\", \"versionStartIncluding\": \"6.6.103\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.12.50\", \"versionStartIncluding\": \"6.12.43\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.16.10\", \"versionStartIncluding\": \"6.16.2\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionStartIncluding\": \"6.15.11\"}], \"operator\": \"OR\"}]}], \"providerMetadata\": {\"orgId\": \"416baaa9-dc9f-4396-8d5f-8c081fb06d67\", \"shortName\": \"Linux\", \"dateUpdated\": \"2026-08-05T12:06:34.191Z\"}}}",
