CVE-2026-46262

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

Description A deadlock occurs in the ASoC fsl xcvr component due to an improper locking mechanism in the fsl xcvr mode put() function. The issue arises when the function attempts to acquire the card->controls rwsem lock while the upper ALSA core function snd ctl elem write() already holds the write lock on the same semaphore for the duration of the operation. Attempting to acquire a read lock while holding a write lock in the same thread leads to a hung task.

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