CVE-2026-23109

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> fs/writeback: skip AS_NO_DATA_INTEGRITY mappings in wait_sb_inodes()<br /> <br /> Above the while() loop in wait_sb_inodes(), we document that we must wait<br /> for all pages under writeback for data integrity. Consequently, if a<br /> mapping, like fuse, traditionally does not have data integrity semantics,<br /> there is no need to wait at all; we can simply skip these inodes.<br /> <br /> This restores fuse back to prior behavior where syncs are no-ops. This<br /> fixes a user regression where if a system is running a faulty fuse server<br /> that does not reply to issued write requests, this causes wait_sb_inodes()<br /> to wait forever.
