{"id":"CVE-2022-49084","summary":"qede: confirm skb is allocated before using","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nqede: confirm skb is allocated before using\n\nqede_build_skb() assumes build_skb() always works and goes straight\nto skb_reserve(). However, build_skb() can fail under memory pressure.\nThis results in a kernel panic because the skb to reserve is NULL.\n\nAdd a check in case build_skb() failed to allocate and return NULL.\n\nThe NULL return is handled correctly in callers to qede_build_skb().","modified":"2026-04-02T08:27:16.686904Z","published":"2025-02-26T01:54:43.099Z","related":["SUSE-SU-2025:1027-1","SUSE-SU-2025:1176-1","SUSE-SU-2025:1183-1","SUSE-SU-2025:1241-1","SUSE-SU-2025:1293-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49084.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/034a92c6a81048128fc7b18d278d52438a13902a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4e910dbe36508654a896d5735b318c0b88172570"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8928239e5e2e460d95b8a0b89f61671625e7ece0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9648adb1b3ece55c657d3a4f52bfee663b710dfe"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b2d6b3db9d1cf80908964036dbe1c52a86b1afb1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c9bdce2359b5f4986eb38d1e81865b3586cc20d2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e1fd0c42acfa22bb34d2ab6a111484f466ab8093"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49084.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-49084"},{"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":"8a8633978b842c88fbcfe00d4e5dde96048f630e"},{"fixed":"9648adb1b3ece55c657d3a4f52bfee663b710dfe"},{"fixed":"034a92c6a81048128fc7b18d278d52438a13902a"},{"fixed":"8928239e5e2e460d95b8a0b89f61671625e7ece0"},{"fixed":"c9bdce2359b5f4986eb38d1e81865b3586cc20d2"},{"fixed":"b2d6b3db9d1cf80908964036dbe1c52a86b1afb1"},{"fixed":"e1fd0c42acfa22bb34d2ab6a111484f466ab8093"},{"fixed":"4e910dbe36508654a896d5735b318c0b88172570"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-49084.json"}}],"schema_version":"1.7.5"}
