Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.1.0-rc8-00588-g76dcd734eca2
Description
The Linux kernel contains a flaw within the ALSA subsystem, specifically in the
snd mts64 interrupt function. A null pointer dereference can occur during interrupt handling when the mts is not initialized. This can lead to a kernel panic, potentially causing system instability or a denial of service. The issue was identified through testing on a qemu platform with specific configurations involving parport and snd-mts64 modules. The root cause is the lack of a check for mts initialization during the interrupt process.Recommendations
Update the Linux kernel to version 6.1.0-rc8-00588-g76dcd734eca2 or a later version that includes the fix.
