Severity ?
8.8 (High) - CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: can: peak_usb: fix use after free bugs After calling peak_usb_netif_rx_ni(skb), dereferencing skb is unsafe. Especially, the can_frame cf which aliases skb memory is accessed after the peak_usb_netif_rx_ni(). Reordering the lines solves the issue.

this is ordinary kernel memory corruption, not a VM escape, IOMMU bypass, or other cross-authority boundary crossing.\\nC:H - This is a use-after-free of an sk_buff/can_frame after ownership transfer to netif_rx; UAF of heap objects enables reclaim and disclosure of freed object contents, so confidentiality is scored High.\\nI:H - The same UAF allows heap reuse of the freed skb object and is treated as providing a corruption/write primitive suitable for control-flow hijack under kernel UAF guidance, so integrity is High.\\nA:H - Use-after-free of skb memory after netif_rx can oops/panic when the object is reused or unmapped, and UAF bugs are scored High availability even when not fully exploited for code execution.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"0a25e1f4f18566b750ebd3ae995af64e23111e63\", \"lessThan\": \"5408824636fa0dfedb9ecb0d94abd573131bfbbe\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0a25e1f4f18566b750ebd3ae995af64e23111e63\", \"lessThan\": \"ddd1416f44130377798c1430b76503513b7497c2\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0a25e1f4f18566b750ebd3ae995af64e23111e63\", \"lessThan\": \"ec939c13c3fff2114479769c8380b7f1a54feca9\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0a25e1f4f18566b750ebd3ae995af64e23111e63\", \"lessThan\": \"50aca891d7a554db0901b245167cd653d73aaa71\", \"versionType\": \"git\"}], \"programFiles\": [\"drivers/net/can/usb/peak_usb/pcan_usb_fd.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"4.0\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"4.0\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"4.19.171\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"4.19.*\"}, {\"status\": \"unaffected\", \"version\": \"5.4.93\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.4.*\"}, {\"status\": \"unaffected\", \"version\": \"5.10.11\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.10.*\"}, {\"status\": \"unaffected\", \"version\": \"5.11\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/net/can/usb/peak_usb/pcan_usb_fd.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/5408824636fa0dfedb9ecb0d94abd573131bfbbe\"}, {\"url\": \"https://git.kernel.org/stable/c/ddd1416f44130377798c1430b76503513b7497c2\"}, {\"url\": \"https://git.kernel.org/stable/c/ec939c13c3fff2114479769c8380b7f1a54feca9\"}, {\"url\": \"https://git.kernel.org/stable/c/50aca891d7a554db0901b245167cd653d73aaa71\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\ncan: peak_usb: fix use after free bugs\\n\\nAfter calling peak_usb_netif_rx_ni(skb), dereferencing skb is unsafe.\\nEspecially, the can_frame cf which aliases skb memory is accessed\\nafter the peak_usb_netif_rx_ni().\\n\\nReordering the lines solves the issue.\"}], \"cpeApplicability\": [{\"nodes\": [{\"negate\": false, \"cpeMatch\": [{\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"4.19.171\", \"versionStartIncluding\": \"4.0\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"5.4.93\", \"versionStartIncluding\": \"4.0\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"5.10.11\", \"versionStartIncluding\": \"4.0\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"5.11\", \"versionStartIncluding\": \"4.0\"}], \"operator\": \"OR\"}]}], \"providerMetadata\": {\"orgId\": \"416baaa9-dc9f-4396-8d5f-8c081fb06d67\", \"shortName\": \"Linux\", \"dateUpdated\": \"2026-08-05T08:48:50.364Z\"}}}",
