CVE-2026-43262

A flaw was found in the Linux kernel's gfs2 filesystem. This vulnerability occurs when the gfs2fiemap function calls iomapfiemap while holding an inode glock a global lock for filesystem operations. If the fiemap buffer is memory mapped to the same inode and accessing it triggers a page fault, it...
