CVE-2024-36019

A vulnerability was found in the Linux kernel’s regmap subsystem. Due to improper indexing in the regcache_maple_drop() function, an out-of-bounds access could corrupt the cache by overwriting parts of it with kernel memory.

A cache-handling flaw in the Linux kernel's regmap subsystem: regcache_maple_drop() can corrupt the maple-tree register cache and read beyond the intended range, returning stale register data or crashing the system. Triggering requires privileged local access to regmap register-cache operations, so Red Hat assesses Attack Privileges High and Confidentiality Low and rates this Moderate (5.1), below external scores (NIST 7.1, CVE.org 7.8).

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
