CVE-2026-90344 wifi: mac80211: disconnect on CSA to channel 0

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: disconnect on CSA to channel 0 The refactor for the CSA parsing erroneously equates channel zero and no information present, leading it to ignore a CSA on an AP that advertises a switch to that invalid channel. Th...

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix mmaplock deadlock on arena lock failure Reported by the Sashiko AI review. arenavmfault returns VMFAULTRETRY when it can't take arena-spinlock, but it never took mmaplock. The fault path assumes a VMFAULTRETRY handler...

CVE-2026-90342

CVE-2026-90342 is a deadlock in the Linux kernel BPF subsystem, specifically in the arena_vm_fault() path. The root cause is that arena_vm_fault() returns VM_FAULT_RETRY when it fails to acquire arena->spinlock, without ever having taken mmap_lock. The fault handler (do_user_addr_fault) then r...
