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 erofs filesystem. The issue occurs when the user mounts the erofs filesystem for the second time, which may cause the decompression thread to hang. This happens due to a sequence of steps where one task obtains nodes from the z erofs lzma head, while another task tries to get a node but finds the z erofs lzma head empty and has to sleep. Even after the first task releases nodes and pushes them into the z erofs lzma head, the second task remains sleeping, leading to a hang.

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