This vulnerability is a use-after-free issue (CWE-416) in ESET Endpoint Antivirus for Linux, which may allow an attacker with high privileges to trigger a kernel panic on the affected system. The CVSS 4.0 vector indicates local attack vector, low attack complexity, no user interaction, and high impact on availability. The affected versions are explicitly 12.0, 12.1, 12.2, 13.0, and 13.1. No vendor advisory or patch information is currently available, and no known exploits are reported in the wild.

Exploitation of this vulnerability can cause a denial of service by triggering a kernel panic, impacting system availability. The attacker requires high privileges and local access to exploit this issue. There is no indication of confidentiality or integrity impact.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, limit local privileged access to trusted users only to reduce risk.
