CVE-2026-72253 (GCVE-0-2026-72253)
Vulnerability from cvelistv5
Published

Modified

Severity ?
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_conntrack_sip: validate skb_dst() before accessing it tc ingress and openvswitch do not guarantee routing information to be available. These subsystems use the conntrack helper infrastructure, and the SIP helper relies on the skb_dst() to be present if sip_external_media is set to 1 (which is disabled by default as a module parameter). This effectively disables the sip_external_media toggle for these subsystems without resulting in a crash.

a remote SIP peer only needs to deliver malicious signaling to an already-configured OVS/tc SIP ALG with sip_external_media enabled, with no authentication or local access.\\nUI:N - No victim user interaction is required; the kernel SIP helper parses attacker-supplied SIP/SDP during conntrack processing in softirq without any user action beyond normal automated packet handling.\\nS:U - A NULL pointer dereference in nf_conntrack_sip causes a kernel oops/panic within the same kernel security domain on the gateway; it does not cross VM, IOMMU, or sandbox boundaries.\\nC:N - The failure is a direct NULL pointer dereference from skb_dst(skb) being NULL on tc/OVS ingress paths; there is no use-after-free, out-of-bounds read, or other memory disclosure primitive.\\nI:N - Accessing skb_dst(skb)-\u003edev when skb_dst is NULL cannot modify memory or hijack control flow beyond the immediate fault; CVSS guidance assigns None for pure NULL-deref crashes without write capability.\\nA:H - The invalid skb_dst dereference in set_expected_rtp_rtcp() during SIP SDP processing causes a kernel oops/panic-class fault, denying availability on the VoIP gateway until reboot; the crash is reliably reproducible with crafted SIP traffic.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"cae3a2627520c3795b54533c5328b77af3405dbe\", \"lessThan\": \"7866116a040b3a23fb094e7d8f7ea3d61b3ac70b\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"cae3a2627520c3795b54533c5328b77af3405dbe\", \"lessThan\": \"c5ef7228be04518d95591fc5369a9c554b19756d\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"cae3a2627520c3795b54533c5328b77af3405dbe\", \"lessThan\": \"0aec339694a56e263d4b22475ff7211d40900830\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"cae3a2627520c3795b54533c5328b77af3405dbe\", \"lessThan\": \"e64a48c50a1ff565a98c6a98d82b5b942868e76e\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"cae3a2627520c3795b54533c5328b77af3405dbe\", \"lessThan\": \"c199ed687c00841daf60e9d131976958583a8c09\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"cae3a2627520c3795b54533c5328b77af3405dbe\", \"lessThan\": \"09755dc62b026076b1d47f83489eb0547c8135e0\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"cae3a2627520c3795b54533c5328b77af3405dbe\", \"lessThan\": \"b843a96252f672332837ea2ecb7c8db0acf68e20\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"cae3a2627520c3795b54533c5328b77af3405dbe\", \"lessThan\": \"e5e24a365a5e024efef63cc49abb345fbd4852c5\", \"versionType\": \"git\"}], \"programFiles\": [\"net/netfilter/nf_conntrack_sip.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"4.3\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"4.3\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"5.10.266\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.10.*\"}, {\"status\": \"unaffected\", \"version\": \"5.15.217\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.15.*\"}, {\"status\": \"unaffected\", \"version\": \"6.1.184\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.148\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.12.101\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.12.*\"}, {\"status\": \"unaffected\", \"version\": \"6.18.42\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.18.*\"}, {\"status\": \"unaffected\", \"version\": \"7.1.5\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"7.1.*\"}, {\"status\": \"unaffected\", \"version\": \"7.2\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"net/netfilter/nf_conntrack_sip.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/7866116a040b3a23fb094e7d8f7ea3d61b3ac70b\"}, {\"url\": \"https://git.kernel.org/stable/c/c5ef7228be04518d95591fc5369a9c554b19756d\"}, {\"url\": \"https://git.kernel.org/stable/c/0aec339694a56e263d4b22475ff7211d40900830\"}, {\"url\": \"https://git.kernel.org/stable/c/e64a48c50a1ff565a98c6a98d82b5b942868e76e\"}, {\"url\": \"https://git.kernel.org/stable/c/c199ed687c00841daf60e9d131976958583a8c09\"}, {\"url\": \"https://git.kernel.org/stable/c/09755dc62b026076b1d47f83489eb0547c8135e0\"}, {\"url\": \"https://git.kernel.org/stable/c/b843a96252f672332837ea2ecb7c8db0acf68e20\"}, {\"url\": \"https://git.kernel.org/stable/c/e5e24a365a5e024efef63cc49abb345fbd4852c5\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nnetfilter: nf_conntrack_sip: validate skb_dst() before accessing it\\n\\ntc ingress and openvswitch do not guarantee routing information to be\\navailable.
