CVE-2026-43262

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> gfs2: fiemap page fault fix<br /> <br /> In gfs2_fiemap(), we are calling iomap_fiemap() while holding the inode<br /> glock. This can lead to recursive glock taking if the fiemap buffer is<br /> memory mapped to the same inode and accessing it triggers a page fault.<br /> <br /> Fix by disabling page faults for iomap_fiemap() and faulting in the<br /> buffer by hand if necessary.<br /> <br /> Fixes xfstest generic/742.
