But the skb is already freed, which will cause UAF bug\nwhen the upper layer resends the skb.\n\nRemove the harmful free.","modified":"2026-03-20T12:22:06.802007Z","published":"2024-10-21T20:06:31.876Z","related":["SUSE-SU-2024:3983-1","SUSE-SU-2024:3985-1","SUSE-SU-2024:4082-1","SUSE-SU-2024:4100-1","SUSE-SU-2024:4131-1","SUSE-SU-2024:4364-1","SUSE-SU-2025:0034-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49026.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/45605c75c52c7ae7bfe902214343aabcfe5ba0ff"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9fc27d22cdb9b1fcd754599d216a8992fed280cd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b46f6144ab89d3d757ead940759c505091626a7d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b775f37d943966f6f77dca402f5a9dedce502c25"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49026.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-49026"},{"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":"5e5d49422dfb035ca9e280cd61d434095c151272"},{"fixed":"b775f37d943966f6f77dca402f5a9dedce502c25"},{"fixed":"9fc27d22cdb9b1fcd754599d216a8992fed280cd"},{"fixed":"b46f6144ab89d3d757ead940759c505091626a7d"},{"fixed":"45605c75c52c7ae7bfe902214343aabcfe5ba0ff"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2022-49026.json"}}],"schema_version":"1.7.5"}
