Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A vulnerability in the Linux kernel has been resolved. The issue is related to the ASoC (Audio System on Chip) mediatek component, where accessing members of a dummy component during probe can result in undefined behavior. This can lead to a kernel panic when a dai link subnode is omitted in the sound card's node in the Devicetree. The vulnerability can be observed in the mt8188 and mt8195 machine sound drivers. To accommodate for both initialized and uninitialized dummy codecs, a check has been added to ensure that num codecs is not zero before accessing the codecs' fields.
Recommendations
To resolve the issue, update the Linux kernel to a version that includes the fix for this vulnerability.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
