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

Description A vulnerability in the Linux kernel has been resolved, specifically in the net/9p/usbg subsystem, where the handling of failed kzalloc() memory allocation was fixed. The issue was identified by the coccinelle tool, which reported an error in the trans usbg.c file, indicating that the allocation function returned NULL instead of ERR PTR on failure. The kzalloc() failure is now handled to manage the NULL return case on memory exhaustion.

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