Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A data-race issue in the Linux kernel has been identified, specifically in the unix dgram peer wake me() function. The unix dgram poll() function calls unix dgram peer wake me() without holding the other lock, and checks if the receive queue is full. To fix this, unix recvq full lockless() should be used instead of unix recvq full(), as the latter can cause a data-race report by KCSAN.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
