Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw exists in the Linux kernel's ALSA PCM memory allocation helpers. A missing lock during a sanity check allows a user to potentially allocate more memory than the predefined maximum size. While this is described as a "soft limit" and unlimited allocation isn't possible, the issue leads to inconsistent behavior. The patch addresses this by covering the size check in the
do alloc pages() function with the card->memory mutex, and adjusting the allocated size to prevent overflow.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
