Overview
About vulnerability
In the Linux kernel, the following vulnerability has been resolved:
ALSA: ice1712: Fix the card leak at probe error with the auto-cleanup
snd_ice1712_probe() performs multiple initialization steps after snd_card_new(), but directly returns on failures from later steps without releasing the ALSA card, causing resource leaks when probing fails.
Use snd_devm_card_new() together with scope-based cleanup via __free(snd_card_unref), and clear the card pointer after successful registration to keep it alive.
