{"id":"CVE-2026-68168","summary":"afs: Fix afs_edit_dir_remove() to get, not find, block 0","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nafs: Fix afs_edit_dir_remove() to get, not find, block 0\n\nFix afs_edit_dir_remove() to use afs_dir_get_block() to get block 0 rather\nthan afs_dir_find_block() as the latter caches the found block in the\nafs_dir_iter and may[*] switch out the page it's on if another\nafs_dir_find_block() is done.  This parallels what afs_edit_dir_add() does.\n\n[*] There's more than one block per page.","modified":"2026-08-18T03:30:55.662012217Z","published":"2026-08-10T11:59:36.633Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68168.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/62d9853aa4ce6e9797b6949804891be14b219752"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bfdfc7782ada6f3a4df7182889b66039f8e4131c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f2b293359924117736218701ebd8b40618d73e6f"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68168.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68168"},{"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":"a5b5beebcf96d5e8a2fc79856c2ac1e93f82478e"},{"fixed":"f2b293359924117736218701ebd8b40618d73e6f"},{"fixed":"bfdfc7782ada6f3a4df7182889b66039f8e4131c"},{"fixed":"62d9853aa4ce6e9797b6949804891be14b219752"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-68168.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.14.0"},{"fixed":"6.18.42"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-68168.json"}}],"schema_version":"1.9.0"}
