{"id":"CVE-2022-49641","summary":"sysctl: Fix data races in proc_douintvec().","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nsysctl: Fix data races in proc_douintvec().\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_douintvec() to use READ_ONCE() and WRITE_ONCE()\ninternally to fix data-races on the sysctl side.  For now, proc_douintvec()\nitself is tolerant to a data-race, but we still need to add annotations on\nthe other subsystem's side.","modified":"2026-04-02T08:27:47.607844Z","published":"2025-02-26T02:23:48.675Z","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-2022-49641.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/4762b532ec9539755aab61445d5da6e1926ccb99"},{"type":"WEB","url":"https://git.kernel.org/stable/c/630c76850d554d7140232e71b5d1663e88cffb54"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d335db59f7fb3353f56e52371f1ee796ae9c8f09"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d5d54714e329f646bd7af4994fc427d88ee68936"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49641.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-49641"},{"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":"e7d316a02f683864a12389f8808570e37fb90aa3"},{"fixed":"d5d54714e329f646bd7af4994fc427d88ee68936"},{"fixed":"d335db59f7fb3353f56e52371f1ee796ae9c8f09"},{"fixed":"630c76850d554d7140232e71b5d1663e88cffb54"},{"fixed":"4762b532ec9539755aab61445d5da6e1926ccb99"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0"},{"last_affected":"70cd763eb1574cac07138be91f474a661e02d694"},{"last_affected":"f4cea51e9a3d536e2ca2b74a958f7c0b4ea733c3"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-49641.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"}]}
