Answer in brief
CVE-2026-72453 records a Unknown severity vulnerability in regcache: Do not overwrite error code when finalizing cache after error. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
