Summary
In the Linux kernel, the following vulnerability has been resolved: ipv4: Handle attempt to delete multipath route when fib_info contains an nh reference Gwangun Jung reported a slab-out-of-bounds access in fib_nh_match: fib_nh_match+0xf98/0x1130 linux-6.0-rc7/net/ipv4/fib_semantics.c:961 fib_table_delete+0x5f3/0xa40 linux-6.0-rc7/net/ipv4/fib_trie.c:1753 inet_rtm_delroute+0x2b3/0x380 linux-6.0-rc7/net/ipv4/fib_frontend.c:874 Separate nexthop objects are mutually exclusive with the legacy multipath spec. Fix fib_nh_match to return if the config for the to be deleted route contains a multipath spec while the fib_info is using a nexthop object.

no races or attacker-uncontrollable conditions are required.\\nPR:L - RTM_DELROUTE/RTM_NEWNEXTHOP require CAP_NET_ADMIN, but that capability is available to an unprivileged user inside a user+network namespace (netlink_net_capable checks the netns user_ns).\\nUI:N - Exploitation needs no victim action; the attacker sets up the nexthop route and issues the delete themselves.\\nS:U - Impact is confined to the local kernel networking stack authority; this is not a VM/IOMMU/sandbox boundary cross.\\nC:H - The bug is a slab out-of-bounds read of struct fib_nh fields past a zero-length fib_nh[] allocation; with a multipath nexthop group, fib_info_num_path() expands the OOB window across adjacent slab memory.\\nI:N - The vulnerable path only reads and compares OOB memory for route matching; there is no out-of-bounds write or memory-corruption write primitive.\\nA:H - The slab OOB access can oops/panic the kernel when it hits unmapped or poisoned memory, matching the reported KASAN slab-out-of-bounds crash.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"493ced1ac47c48bb86d9d4e8e87df8592be85a0e\", \"lessThan\": \"cc3cd130ecfb8b0ae52e235e487bae3f16a24a32\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"493ced1ac47c48bb86d9d4e8e87df8592be85a0e\", \"lessThan\": \"0b5394229ebae09afc07aabccb5ffd705ffd250e\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"493ced1ac47c48bb86d9d4e8e87df8592be85a0e\", \"lessThan\": \"25174d91e4a32a24204060d283bd5fa6d0ddf133\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"493ced1ac47c48bb86d9d4e8e87df8592be85a0e\", \"lessThan\": \"bb20a2ae241be846bc3c11ea4b3a3c69e41d51f2\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"493ced1ac47c48bb86d9d4e8e87df8592be85a0e\", \"lessThan\": \"61b91eb33a69c3be11b259c5ea484505cd79f883\", \"versionType\": \"git\"}], \"programFiles\": [\"net/ipv4/fib_semantics.c\", \"tools/testing/selftests/net/fib_nexthops.sh\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"5.3\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"5.3\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"5.4.226\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.4.*\"}, {\"status\": \"unaffected\", \"version\": \"5.10.158\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.10.*\"}, {\"status\": \"unaffected\", \"version\": \"5.15.82\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.15.*\"}, {\"status\": \"unaffected\", \"version\": \"6.0.12\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.0.*\"}, {\"status\": \"unaffected\", \"version\": \"6.1\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"net/ipv4/fib_semantics.c\", \"tools/testing/selftests/net/fib_nexthops.sh\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/cc3cd130ecfb8b0ae52e235e487bae3f16a24a32\"}, {\"url\": \"https://git.kernel.org/stable/c/0b5394229ebae09afc07aabccb5ffd705ffd250e\"}, {\"url\": \"https://git.kernel.org/stable/c/25174d91e4a32a24204060d283bd5fa6d0ddf133\"}, {\"url\": \"https://git.kernel.org/stable/c/bb20a2ae241be846bc3c11ea4b3a3c69e41d51f2\"}, {\"url\": \"https://git.kernel.org/stable/c/61b91eb33a69c3be11b259c5ea484505cd79f883\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nipv4: Handle attempt to delete multipath route when fib_info contains an nh reference\\n\\nGwangun Jung reported a slab-out-of-bounds access in fib_nh_match:\\n    fib_nh_match+0xf98/0x1130 linux-6.0-rc7/net/ipv4/fib_semantics.c:961\\n    fib_table_delete+0x5f3/0xa40 linux-6.0-rc7/net/ipv4/fib_trie.c:1753\\n    inet_rtm_delroute+0x2b3/0x380 linux-6.0-rc7/net/ipv4/fib_frontend.c:874\\n\\nSeparate nexthop objects are mutually exclusive with the legacy\\nmultipath spec.
