In the Linux kernel, the following vulnerability has been resolved: gfs2: fiemap page fault fix In gfs2_fiemap(), we are calling iomap_fiemap() while holding the inode glock. This can lead to recursive glock taking if the fiemap buffer is memory mapped to the same inode and accessing it triggers a page fault. Fix by disabling page faults for iomap_fiemap() and faulting in the buffer by hand if necessary. Fixes xfstest generic/742. A flaw was found in the Linux kernel's gfs2 filesystem. This vulnerability occurs when the gfs2_fiemap() function calls iomap_fiemap() 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 can lead to recursive glock taking. This can result in a deadlock, potentially causing a Denial of Service (DoS) for the system.
