CVE-2026-53192

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A use-after-free issue exists in the ALSA timer component. When a userspace timer is closed and the snd timer free() function is called to release resources, other active tasks may still hold the timer instance. Because the SNDRV TIMER IOCTL PARAMS ioctl is not protected by a mutex, concurrent access can lead to a use-after-free condition within the snd timer user params() function. Use-after-free is a scenario where a program continues to use a pointer after the memory it points to has been freed.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
