CVE-2026-89520

CVE-2026-89520 is a race condition in the Linux kernel's core scheduling component. When pick_next_task() releases the runqueue lock during task selection, sibling locks become momentarily free, allowing __sched_core_flip(false) to rebind rq_lockp() mid-selection. The selection then resumes on sp...

CVE-2026-80856

CVE-2026-80856 is a lock leak in the Linux kernel FUSE subsystem. In fuse_do_setattr(), the function acquires filemap_invalidate_lock() for a DAX truncate but fails to release it when write_inode_now() returns an error (e.g., the FUSE daemon returns -EIO ). The leaked rwsem causes any subsequent ...

CVE-2026-80855

CVE-2026-80855 affects the Linux kernel FUSE filesystem. In fuse_open(), when a DAX truncate (O_TRUNC) triggers filemap_invalidate_lock(), a subsequent failure in fuse_dax_break_layouts() (e.g., returning -ERESTARTSYS after a signal interrupts the wait for busy DAX pages to drain) causes the code...
