CVE-2026-80859

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...
