| Vector | AV:L/AC:H/Au:M/C:P/I:P/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw exists in the Linux kernel’s ASoC (Advanced Linux Sound Architecture) Intel avs (Audio Video Stream) component. Specifically, the
avs dai fe shutdown() function, responsible for shutting down a HOST HDAudio stream, can lead to errors when interacting with period-elapsed work that is still servicing interrupts. This occurs because the shutdown procedure frees the DAI’s private context while the period-elapsed work is still active, potentially resulting in a slab-use-after-free condition or other errors. The avs dai fe shutdown() function handles the shutdown procedure.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
