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...

CVE-2026-43262

CVE-2026-43262 stems from a Linux kernel gfs2 fiemap page fault: gfs2_fiemap() calls iomap_fiemap() while holding the inode glock, risking recursive glock taking if the fiemap buffer maps to the same inode. The fix disables page faults for iomap_fiemap() and faults in the buffer by hand when need...
