{"id":"CVE-2022-49634","summary":"sysctl: Fix data-races in proc_dou8vec_minmax().","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nsysctl: Fix data-races in proc_dou8vec_minmax().\n\nA sysctl variable is accessed concurrently, and there is always a chance\nof data-race.  So, all readers and writers need some basic protection to\navoid load/store-tearing.\n\nThis patch changes proc_dou8vec_minmax() to use READ_ONCE() and\nWRITE_ONCE() internally to fix data-races on the sysctl side.  For now,\nproc_dou8vec_minmax() itself is tolerant to a data-race, but we still\nneed to add annotations on the other subsystem's side.","modified":"2026-04-02T08:27:46.831443Z","published":"2025-02-26T02:23:45.254Z","related":["SUSE-SU-2025:1027-1","SUSE-SU-2025:1176-1","SUSE-SU-2025:1183-1","SUSE-SU-2025:1241-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49634.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/5f776daef0b5354615ec4b4234cd9539ca05f273"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7dee5d7747a69aa2be41f04c6a7ecfe3ac8cdf18"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e58b02e445463065b4078bf621561da75197853f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f177b382c33900d0e5a9766493c11a1074076f78"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49634.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-49634"},{"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":"389dab6142d742f91010f38de0f1f2f440b97e1b"},{"fixed":"f177b382c33900d0e5a9766493c11a1074076f78"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"cb9444130662c6c13022579c861098f212db2562"},{"fixed":"e58b02e445463065b4078bf621561da75197853f"},{"fixed":"5f776daef0b5354615ec4b4234cd9539ca05f273"},{"fixed":"7dee5d7747a69aa2be41f04c6a7ecfe3ac8cdf18"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-49634.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
