This also requires to cell to be\nremoved from net-\u003ecells_dyn_ino in afs_destroy_cell_work() rather than in\nafs_cell_destroy() as the latter runs in RCU cleanup context and sleeping\nlocks cannot be taken there.","modified":"2026-08-18T03:56:42.488602620Z","published":"2026-08-15T05:56:07.916Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72372.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2ffb70a8a01988046bb207b7d0af9358a8337378"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4d8a2fe8847859f4fa4e9a2fa1221c9c1158e66b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/55e841836c6f4646490f7b0347192b7a92d431ba"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e94f92fd56c553a8bf9421c3289e1b85c7c08857"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72372.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72372"},{"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":"537b0105952578531f748c7fb3ce36ae9a514784"},{"fixed":"4d8a2fe8847859f4fa4e9a2fa1221c9c1158e66b"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"1d0b929fc070b4115403a0a6206a0c6a62dd61f5"},{"fixed":"2ffb70a8a01988046bb207b7d0af9358a8337378"},{"fixed":"e94f92fd56c553a8bf9421c3289e1b85c7c08857"},{"fixed":"55e841836c6f4646490f7b0347192b7a92d431ba"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.12.97"},{"fixed":"6.12.101"}]}],"versions":["v6.12.100","v6.12.99","v6.12.98","v6.12.97"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72372.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.12.101"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.40"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.15.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72372.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
