CVE-2024-56533

The CVE-2024-56533 vulnerability affects the Linux kernel’s ALSA usx2y driver. It stems from using snd_card_free() during USB disconnection, which waits for all open fds to close and can delay release, potentially blocking USB IOCTLs and causing a soft lockup. The advisory notes replacing snd_car...

CVE-2024-56532

CVE-2024-56532 affects the Linux kernel’s ALSA us122l code path. The USB disconnect callback previously waited for all fds to close due to snd_card_free(), which could block upper-layer USB ioctls and trigger a soft lockup. The cited fixes switch to snd_card_free_when_closed(), enabling asynchron...
