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.
