Name of the Vulnerable Software and Affected Versions:
Linux kernel (affected versions not specified)
Description:
A vulnerability in the Linux kernel has been resolved, related to the error handling of the
xa alloc cyclic() function. If this function returns 1 (indicating wrapping), it will return ERR PTR(1), causing IS ERR() to be false. This can lead to the dereference of an unallocated pointer. The issue is fixed by checking if the error value is less than zero. This problem was not discovered through a real-world use case but was noticed during review. Credit for discovering the issue is given to Pierre.Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
