This hides the error condition from the caller of\nregcache_init(), and can cause NULL pointer dereferences when the regcache\nis later accessed.","state":0,"publishedAt":"2026-08-15T05:57:00.921+00:00","modifiedAt":"2026-08-17T05:14:57.028+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/base/regmap/regcache.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"94a3a95f03154d8d4c6206950a7f6ef9a30baec6\",\n                            \"lessThan\": \"9f171aa115ec76be02c76c5765cd2c865279e34a\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"94a3a95f03154d8d4c6206950a7f6ef9a30baec6\",\n                            \"lessThan\": \"9108f7fa493b4c88cbc09503e0c164244456bad5\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/base/regmap/regcache.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.19\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.19\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.1.5\",\n                            \"lessThanOrEqual\": \"7.1.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/9f171aa115ec76be02c76c5765cd2c865279e34a","https://git.kernel.org/stable/c/9108f7fa493b4c88cbc09503e0c164244456bad5"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-72453","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-72453","identifiers":["CVE-2026-72453"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
