kernel: Linux kernel: Denial of service or memory corruption due to a data race in ALSA PCM memory allocation

A flaw was found in the Linux kernel. A data race in the Advanced Linux Sound Architecture ALSA Pulse-Code Modulation PCM memory allocation helpers allows a local user to bypass sanity checks. This can lead to the allocation of more memory than intended, potentially resulting in a denial of servi...

UBUNTU-CVE-2024-26927

In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: Add some bounds checking to firmware data Smatch complains about "head-fullsize - head-headersize" can underflow. To some extent, we're always going to have to trust the firmware a bit. However, it's easy enough to add...

SUSE CVE-2021-47096

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

A flaw was found in the Linux kernel's ALSA ymfpci sound driver. During a previous refactoring commit that removed sndcardymfpciremove, the sndcardnew call was not updated to snddevmcardnew. This omission means sndcardfree is never called during module unload, leading to a kernel oops when...
