CVE-2026-89520
CVE-2026-89520 affects the Linux kernel's core scheduling subsystem (sched/core). The root cause is a lock-ordering bug in pick_next_task(): when a ->pick_task() call releases the rq lock mid-selection, every sibling __lock becomes momentarily free, allowing __sched_core_flip(false) to complet...
CVE-2026-89520 sched/core: Make core-sched flips wait for in-flight selections
In the Linux kernel, the following vulnerability has been resolved: sched/core: Make core-sched flips wait for in-flight selections Core scheduling's picknexttask operates on all sibling rqs under one acquisition of the shared core-wide lock. A -picktask that releases the rq lock leaves every...

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...
