Description
This security bulletin contains information about 1 security vulnerability.
1) Use After Free (CVE-ID: CVE-2026-23322)
The vulnerability allows a local user to execute arbitrary code or cause a denial of service.
The vulnerability exists due to use-after-free in the IPMI subsystem when handling message sending errors. A local user can trigger a sequence of sender errors to cause list corruption and use-after-free, leading to memory corruption and potential arbitrary code execution or system crash.
Exploitation requires the ability to send messages through the IPMI interface, which is typically accessible to local users with appropriate permissions.
