{"id":"CVE-2022-49413","summary":"bfq: Update cgroup information before merging bio","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbfq: Update cgroup information before merging bio\n\nWhen the process is migrated to a different cgroup (or in case of\nwriteback just starts submitting bios associated with a different\ncgroup) bfq_merge_bio() can operate with stale cgroup information in\nbic. Thus the bio can be merged to a request from a different cgroup or\nit can result in merging of bfqqs for different cgroups or bfqqs of\nalready dead cgroups and causing possible use-after-free issues. Fix the\nproblem by updating cgroup information in bfq_merge_bio().","modified":"2026-04-11T12:44:01.561650Z","published":"2025-02-26T02:12:34.604Z","related":["SUSE-SU-2025:1027-1","SUSE-SU-2025:1176-1","SUSE-SU-2025:1183-1","SUSE-SU-2025:1194-1","SUSE-SU-2025:1241-1","SUSE-SU-2025:1263-1","SUSE-SU-2025:1293-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49413.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2a1077f17169a6059992a0bbdb330e0abad1e6d9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b06691af08b41dfd81052a3362514d9827b44bb1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d9165200c5627a2cf4408eefabdf0058bdf95e1a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/da9f3025d595956410ceaab2bea01980d7775948"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e8821f45612f2e6d9adb9c6ba0fb4184f57692aa"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ea591cd4eb270393810e7be01feb8fde6a34fbbe"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49413.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-49413"},{"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":"e21b7a0b988772e82e7147e1c659a5afe2ae003c"},{"fixed":"da9f3025d595956410ceaab2bea01980d7775948"},{"fixed":"b06691af08b41dfd81052a3362514d9827b44bb1"},{"fixed":"e8821f45612f2e6d9adb9c6ba0fb4184f57692aa"},{"fixed":"d9165200c5627a2cf4408eefabdf0058bdf95e1a"},{"fixed":"2a1077f17169a6059992a0bbdb330e0abad1e6d9"},{"fixed":"ea591cd4eb270393810e7be01feb8fde6a34fbbe"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2022-49413.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.12.0"},{"fixed":"5.4.198"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.5.0"},{"fixed":"5.10.121"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.46"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"5.17.14"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.18.0"},{"fixed":"5.18.3"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2022-49413.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
