      <title>CVE-2026-53287 — audit: fix incorrect inheritable capability in CAPSET records</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-53287</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Linux&lt;/p&gt;
&lt;p&gt;In the Linux kernel, the following vulnerability has been resolved:&lt;/p&gt;
&lt;p&gt;audit: fix incorrect inheritable capability in CAPSET records&lt;/p&gt;
&lt;p&gt;__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.&lt;/p&gt;
&lt;p&gt;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.&lt;/p&gt;
&lt;p&gt;The bug has been present since the original introduction of CAPSET
audit records in 2008.&lt;/p&gt;</description>
