Title
hsr: Prevent use after free in prp_create_tagged_frame()
Summary
In the Linux kernel, the following vulnerability has been resolved: hsr: Prevent use after free in prp_create_tagged_frame() The prp_fill_rct() function can fail. In that situation, it frees the skb and returns NULL. Meanwhile on the success path, it returns the original skb. So it's straight forward to fix bug by using the returned value.

the vulnerable TX tagging path runs when the DANP master sends frames, which an adjacent peer can elicit (e.g. ARP replies) on the same LAN segment.\\nAC:L - This is a deterministic use-after-free once padding allocation fails; an adjacent attacker can flood short-frame elicitation and stress GFP_ATOMIC memory, and UAF bugs are scored AC:L unless the attacker cannot influence the failure condition.\\nPR:N - Triggering requires only unauthenticated L2 traffic on the PRP LAN (e.g. ARP requests that cause short replies through the master); no host account or capability is needed.\\nUI:N - Once the PRP interface is up in its normal industrial deployment, attacker-sent LAN frames alone drive the reply/TX path into prp_create_tagged_frame() with no victim interaction.\\nS:U - The UAF corrupts host kernel skb/heap state within the same OS security authority and does not cross a VM, IOMMU, or sandbox boundary.\\nC:H - Use-after-free of the skb lets a reclaimed object be read through subsequent TX path accesses, enabling arbitrary kernel information disclosure per UAF guidance.\\nI:H - hsr_forward_do() writes skb-\u003edev and hsr_xmit() mutates/transmits the freed skb, yielding heap corruption and write/control-flow primitives characteristic of exploitable kernel UAFs.\\nA:H - Using the freed skb for TX and later free paths causes kernel oops/panic or double-free crashes, so availability impact is a full host denial of service.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"451d8123f89791bb628277c0bdb4cae34a3563e6\", \"lessThan\": \"ddf4e04e946aaa6c458b8b6829617cc44af2bffd\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"451d8123f89791bb628277c0bdb4cae34a3563e6\", \"lessThan\": \"a1a485e45d24b1cd8fe834fd6f1b06e2903827da\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"451d8123f89791bb628277c0bdb4cae34a3563e6\", \"lessThan\": \"6086258bd5ea7b5c706ff62da42b8e271b2401db\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"451d8123f89791bb628277c0bdb4cae34a3563e6\", \"lessThan\": \"1787b9f0729d318d67cf7c5a95f0c3dba9a7cc18\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"451d8123f89791bb628277c0bdb4cae34a3563e6\", \"lessThan\": \"d103fb6726904e353b4773188ee3d3acb4078363\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"451d8123f89791bb628277c0bdb4cae34a3563e6\", \"lessThan\": \"876f8ab52363f649bcc74072157dfd7adfbabc0d\", \"versionType\": \"git\"}], \"programFiles\": [\"net/hsr/hsr_forward.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"5.9\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"5.9\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"5.10.201\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.10.*\"}, {\"status\": \"unaffected\", \"version\": \"5.15.139\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.15.*\"}, {\"status\": \"unaffected\", \"version\": \"6.1.63\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.5.12\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.5.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.2\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.7\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"net/hsr/hsr_forward.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/ddf4e04e946aaa6c458b8b6829617cc44af2bffd\"}, {\"url\": \"https://git.kernel.org/stable/c/a1a485e45d24b1cd8fe834fd6f1b06e2903827da\"}, {\"url\": \"https://git.kernel.org/stable/c/6086258bd5ea7b5c706ff62da42b8e271b2401db\"}, {\"url\": \"https://git.kernel.org/stable/c/1787b9f0729d318d67cf7c5a95f0c3dba9a7cc18\"}, {\"url\": \"https://git.kernel.org/stable/c/d103fb6726904e353b4773188ee3d3acb4078363\"}, {\"url\": \"https://git.kernel.org/stable/c/876f8ab52363f649bcc74072157dfd7adfbabc0d\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nhsr: Prevent use after free in prp_create_tagged_frame()\\n\\nThe prp_fill_rct() function can fail.
