CVE-2026-53287

audit: fix incorrect inheritable capability in CAPSET records

State: Published
Severity: Not scored
Published: Jun 26, 2026

Description

In the Linux kernel, the following vulnerability has been resolved:

audit: fix incorrect inheritable capability in CAPSET records

__audit_log_capset() records the effective capability set into the inheritable field due to a copy-paste error. Every CAPSET audit record therefore reports cap_pi (process inheritable) with the value of cap_effective instead of cap_inheritable.

This silently corrupts audit data used for compliance and forensic analysis: an attacker who modifies inheritable capabilities to prepare for a privilege-escalating exec would have the change masked in the audit trail.

The bug has been present since the original introduction of CAPSET audit records in 2008.
