CVE-2026-80804

In the Linux kernel, the following vulnerability has been resolved: xfs: restore nofs context unconditionally in xfstransroll When xfstranscommit fails in xfstransroll, the NOFS context is cleared but only restored in the success path. This leaves the error path without nofs protection, causing a...

CVE-2026-80859 fuse: fix missing barrier when checking io-uring readiness

In the Linux kernel, the following vulnerability has been resolved: fuse: fix missing barrier when checking io-uring readiness fuseblockalloc reads fch-initialized and then fch-iouring. fch-iouring is set before fch-initialized, ordered by the smpwmb in fusechansetintialized, but fuseblockalloc h...

CVE-2026-80859

CVE-2026-80859 affects the Linux kernel FUSE (Filesystem in Userspace) subsystem. The root cause is a missing read memory barrier (smp_rmb()) in fuse_block_alloc(). The function reads fch->initialized followed by fch->io_uring, but lacks the barrier needed to pair with the smp_wmb() in fuse...

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...
