Linux Kernel gfs2 Vulnerability - Quota Initialization Issue

CVE-2026-97520

What is CVE-2026-97520?

A vulnerability exists in the Linux kernel's gfs2 module related to the quota initialization process. The issue was addressed by modifying the increment logic of the iterator used in the gfs2_quota_init() function. This change enhances clarity by moving the iterator increment outside the loop body, which prevents interference between pointer advancement and duplicate-slot management. Proper handling of this iterator ensures that the function operates correctly and avoids potential logic flaws.
