About this tag
CVE-2024-42079 is a NULL-pointer dereference vulnerability in the Linux kernel's Global File System 2 (GFS2) implementation. It arises from a race condition between outstanding glock work and an unmount path, which can leave a pointer (sdp->sd_jdesc) NULL. Microsoft's advisory for Azure Linux states that the distribution includes the affected open-source library and is potentially vulnerable.

Discussions on WindowsForum.com focus on understanding the scope of the vulnerability, the implications of Microsoft's advisory, and the risk to systems using GFS2.
