CVE-2026-72453

Full vulnerability record from the local CVENow database.

Description

In the Linux kernel, the following vulnerability has been resolved: regcache: Do not overwrite error code when finalizing cache after error During regcache initialization, if an error occurs in the cache_ops->populate callback, and if cache operations include an exit callback, the error code from populate() is overwritten with the return value from exit(). This hides the error condition from the caller of regcache_init(), and can cause NULL pointer dereferences when the regcache is later accessed.
