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-2026-80845

CVE-2026-80845 affects the Linux kernel xfrm subsystem, specifically the NAT keepalive worker. The root cause is an AB-BA lock inversion : nat_keepalive_work() acquires x->lock while holding xfrm_state_lock, whereas the SA deletion path (xfrm_state_delete() / __xfrm_state_delete()) takes the s...

SUSE CVE-2026-56855

Previously, after a channel has been established, a malicious peer could send crafted messages that would deadlock the entire connection. Now, we handle all RFC 4254 channel messages; global requests are handled explicitly. Then, treat all other messages as a protocol error and tear the connectio...
