CVE-2023-54308

Estado: AplazadaAlta (7.8)—

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

ALSA: ymfpci: Create card with device-managed snd_devm_card_new()

snd_card_ymfpci_remove() was removed in commit c6e6bb5eab74 ("ALSA: ymfpci: Allocate resources with device-managed APIs"), but the call to snd_card_new() was not replaced with snd_devm_card_new().

Since there was no longer a call to snd_card_free, unloading the module would eventually result in Oops:
