CVE-2026-58977

Unknown
Published: Translated: NVD NIST

Summary

In is_valid_header of timed_cache_item.c, there is a possible out-of-bounds write due to a missing bounds check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.

Risk Assessment

A local attacker could exploit this to escalate privileges in the System context, potentially leading to full device compromise. The lack of required user interaction increases the risk.

Recommendation

Update the system to a version containing the fix that adds a bounds check in is_valid_header. Restrict access to System-privileged functionality to trusted components only.
