{"id":"CVE-2026-72453","summary":"regcache: Do not overwrite error code when finalizing cache after error","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nregcache: Do not overwrite error code when finalizing cache after error\n\nDuring regcache initialization, if an error occurs in the\ncache_ops-\u003epopulate callback, and if cache operations include an exit\ncallback, the error code from populate() is overwritten with the return\nvalue from exit(). This hides the error condition from the caller of\nregcache_init(), and can cause NULL pointer dereferences when the regcache\nis later accessed.","modified":"2026-08-18T03:31:08.517871636Z","published":"2026-08-15T05:57:00.921Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72453.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/9108f7fa493b4c88cbc09503e0c164244456bad5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9f171aa115ec76be02c76c5765cd2c865279e34a"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72453.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72453"},{"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":"94a3a95f03154d8d4c6206950a7f6ef9a30baec6"},{"fixed":"9f171aa115ec76be02c76c5765cd2c865279e34a"},{"fixed":"9108f7fa493b4c88cbc09503e0c164244456bad5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72453.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72453.json"}}],"schema_version":"1.9.0"}
