The size of bpf_jit_limit\nis long, so we need to add a paired READ_ONCE() to avoid load-tearing.","modified":"2026-04-02T08:28:06.058579Z","published":"2025-06-18T11:00:31.782Z","related":["SUSE-SU-2025:03204-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49967.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0947ae1121083d363d522ff7518ee72b55bd8d29"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ba632ad0bacb13197a8f38e7526448974e87f292"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49967.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-49967"},{"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":"ede95a63b5e84ddeea6b0c473b36ab8bfd8c6ce3"},{"fixed":"ba632ad0bacb13197a8f38e7526448974e87f292"},{"fixed":"0947ae1121083d363d522ff7518ee72b55bd8d29"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0"},{"last_affected":"c98446e1bab6253ddce7144cc2a91c400a323839"},{"last_affected":"a1fe647042affe713a17243cd10e9b25f3d83948"},{"last_affected":"43caa29c99db5a41b204e8ced01b00e151335ca8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-49967.json"}}],"schema_version":"1.7.5"}
