CVE-2025-39920

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

Description The do validate mem() function lacks error handling for the add interval() call. A failure in kmalloc() within add interval() could lead to a null pointer being added to a linked list, resulting in an illegal memory access during a subsequent call to sub interval(). The patch addresses this by adding error handling to add interval(), causing the function to return early with an error code if add interval() fails.

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