CVE-2024-56531: ALSA: caiaq: Use snd_card_free_when_closed() at disconnection

Published Dec 27, 2024

Updated

In the Linux kernel, the following vulnerability has been resolved:

ALSA: caiaq: Use sndcardfreewhenclosed() at disconnection

The USB disconnect callback is supposed to be short and not too-long waiting. OTOH, the current code uses sndcardfree() at disconnection, but this waits for the close of all used fds, hence it can take long. It eventually blocks the upper layer USB ioctls, which may trigger a soft lockup.

An easy workaround is to replace sndcardfree() with sndcardfreewhenclosed(). This variant returns immediately while the release of resources is done asynchronously by the card device release at the last close.

This patch also splits the code to the disconnect and the free phases; the former is called immediately at the USB disconnect callback while the latter is called from the card destructor.

This CVE was automatically created from a reference found in an email or other text. If you are reading this, then this CVE entry is probably erroneous, since this text should be replaced by the official CVE description automatically.
