Vulnerability from cvelistv5
Published

Modified

Severity ?
8.2 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: sctp: fix a potential overflow in sctp_ifwdtsn_skip Currently, when traversing ifwdtsn skips with _sctp_walk_ifwdtsn, it only checks the pos against the end of the chunk. However, the data left for the last pos may be < sizeof(struct sctp_ifwdtsn_skip), and dereference it as struct sctp_ifwdtsn_skip may cause coverflow. This patch fixes it by checking the pos against "the end of the chunk - sizeof(struct sctp_ifwdtsn_skip)" in sctp_ifwdtsn_skip, similar to sctp_fwdtsn_skip.

A remote peer reaches it by sending crafted SCTP packets over an established association.\nAC:L - Once an association has negotiated PR-SCTP and stream interleaving, the attacker fully controls chunk length and contents and can deterministically make the final skip entry shorter than sizeof(struct sctp_ifwdtsn_skip). No race or uncontrollable memory layout is required.\nPR:N - Exploitation needs only being the remote SCTP peer of a service that accepts associations with interleaving enabled; no local account, capability, or authenticated privilege on the victim is required.\nUI:N - The attacker initiates the association and sends the malformed I-FWD-TSN; no additional victim action (mount, open, click) is required at exploit time.\nS:U - The out-of-bounds read and any resulting fault stay within the same host kernel authority and do not cross a VM, IOMMU, or sandbox boundary.\nC:L - The walk can read up to 7 bytes past the chunk (and past skb_tail_pointer into adjacent/uninitialized kernel memory). That is a real OOB read but strictly bounded to a few bytes and those bytes are only used as stream/mid/flags internally, not returned to the attacker.\nI:N - The defect is an out-of-bounds read only; stream IDs are still bounds-checked against incnt before use, and there is no OOB write or memory-corruption write primitive. Any stream-skip side effects are within what a peer can already do with a well-formed I-FWD-TSN.\nA:H - Reading past skb_tail_pointer into unmapped or invalid memory can oops/panic the kernel, and a remote peer can trigger this repeatedly on a vulnerable interleaving-enabled association."

A remote peer reaches it by sending crafted SCTP packets over an established association.\\nAC:L - Once an association has negotiated PR-SCTP and stream interleaving, the attacker fully controls chunk length and contents and can deterministically make the final skip entry shorter than sizeof(struct sctp_ifwdtsn_skip). No race or uncontrollable memory layout is required.\\nPR:N - Exploitation needs only being the remote SCTP peer of a service that accepts associations with interleaving enabled; no local account, capability, or authenticated privilege on the victim is required.\\nUI:N - The attacker initiates the association and sends the malformed I-FWD-TSN; no additional victim action (mount, open, click) is required at exploit time.\\nS:U - The out-of-bounds read and any resulting fault stay within the same host kernel authority and do not cross a VM, IOMMU, or sandbox boundary.\\nC:L - The walk can read up to 7 bytes past the chunk (and past skb_tail_pointer into adjacent/uninitialized kernel memory). That is a real OOB read but strictly bounded to a few bytes and those bytes are only used as stream/mid/flags internally, not returned to the attacker.\\nI:N - The defect is an out-of-bounds read only; stream IDs are still bounds-checked against incnt before use, and there is no OOB write or memory-corruption write primitive. Any stream-skip side effects are within what a peer can already do with a well-formed I-FWD-TSN.\\nA:H - Reading past skb_tail_pointer into unmapped or invalid memory can oops/panic the kernel, and a remote peer can trigger this repeatedly on a vulnerable interleaving-enabled association.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"0fc2ea922c8ad5520c80f03facbf396c81dce802\", \"lessThan\": \"4fbd094d4131a10d06a45d64158567052a35b3f4\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0fc2ea922c8ad5520c80f03facbf396c81dce802\", \"lessThan\": \"ad831a7079c99c01e801764b53bc9997c2e9c0f7\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0fc2ea922c8ad5520c80f03facbf396c81dce802\", \"lessThan\": \"79b28f42214a3d0d6a8c514db3602260bd5d6cb5\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0fc2ea922c8ad5520c80f03facbf396c81dce802\", \"lessThan\": \"6109f5b13ce3e3e537db6f18976ec0e9118d1c6f\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0fc2ea922c8ad5520c80f03facbf396c81dce802\", \"lessThan\": \"5c9367ac5a22d71841bcd00130f9146c9b227d57\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0fc2ea922c8ad5520c80f03facbf396c81dce802\", \"lessThan\": \"ad988e9b5ff04607e624a459209e8c2d0c15fc73\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0fc2ea922c8ad5520c80f03facbf396c81dce802\", \"lessThan\": \"32832a2caf82663870126c5186cf8f86c8b2a649\", \"versionType\": \"git\"}], \"programFiles\": [\"net/sctp/stream_interleave.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"4.16\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"4.16\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"4.19.281\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"4.19.*\"}, {\"status\": \"unaffected\", \"version\": \"5.4.241\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.4.*\"}, {\"status\": \"unaffected\", \"version\": \"5.10.178\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.10.*\"}, {\"status\": \"unaffected\", \"version\": \"5.15.108\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.15.*\"}, {\"status\": \"unaffected\", \"version\": \"6.1.25\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.2.12\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.2.*\"}, {\"status\": \"unaffected\", \"version\": \"6.3\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"net/sctp/stream_interleave.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/4fbd094d4131a10d06a45d64158567052a35b3f4\"}, {\"url\": \"https://git.kernel.org/stable/c/ad831a7079c99c01e801764b53bc9997c2e9c0f7\"}, {\"url\": \"https://git.kernel.org/stable/c/79b28f42214a3d0d6a8c514db3602260bd5d6cb5\"}, {\"url\": \"https://git.kernel.org/stable/c/6109f5b13ce3e3e537db6f18976ec0e9118d1c6f\"}, {\"url\": \"https://git.kernel.org/stable/c/5c9367ac5a22d71841bcd00130f9146c9b227d57\"}, {\"url\": \"https://git.kernel.org/stable/c/ad988e9b5ff04607e624a459209e8c2d0c15fc73\"}, {\"url\": \"https://git.kernel.org/stable/c/32832a2caf82663870126c5186cf8f86c8b2a649\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nsctp: fix a potential overflow in sctp_ifwdtsn_skip\\n\\nCurrently, when traversing ifwdtsn skips with _sctp_walk_ifwdtsn, it only\\nchecks the pos against the end of the chunk.
