{"id":"CVE-2022-49008","summary":"can: can327: can327_feed_frame_to_netdev(): fix potential skb leak when netdev is down","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ncan: can327: can327_feed_frame_to_netdev(): fix potential skb leak when netdev is down\n\nIn can327_feed_frame_to_netdev(), it did not free the skb when netdev\nis down, and all callers of can327_feed_frame_to_netdev() did not free\nallocated skb too. That would trigger skb leak.\n\nFix it by adding kfree_skb() in can327_feed_frame_to_netdev() when netdev\nis down. Not tested, just compiled.","modified":"2026-04-02T08:27:13.446374Z","published":"2024-10-21T20:06:20.158Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49008.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/797b1d9fc0e1f4351e4ad49b078c1a3cdc0d4a08"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8fa452cfafed521aaf5a18c71003fe24b1ee6141"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49008.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-49008"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"43da2f07622f41376c7ddab8f73dc2b1d3ab9715"},{"fixed":"797b1d9fc0e1f4351e4ad49b078c1a3cdc0d4a08"},{"fixed":"8fa452cfafed521aaf5a18c71003fe24b1ee6141"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-49008.json"}}],"schema_version":"1.7.5"}
