A double release of a pin controller resource in the cs42l43 driver can trigger a double free in kernel space. This flaw, classified as CWE-1341, may lead to a kernel panic or timing violation that causes the system to become unavailable. The defect does not directly expose data but undermines the operational stability of the affected host.

Any installation of the Linux kernel that contains the cirrus cs42l43 pin controller driver and has not incorporated the recent commit that removes the redundant release is affected. Version information is not specified, so users should examine kernel releases against the commit identifying the double‑put resolution to determine applicability.

The EPSS score of less than 1 % indicates a low probability of recent exploitation, and the vulnerability is not listed in the CISA KEV catalog. Nonetheless, because the flaw resides in kernel mode, an attacker with local or privilege‑escalation capabilities could trigger a crash and cause a denial of service. The lack of a formal CVSS score makes severity assessment ambiguous, but the potential for a system‑wide outage suggests high impact if exploited.
