CVE-2026-23392

The CVE-2026-23392 vulnerability affects the Linux kernel nf_tables flowtable handling. Root cause: during error paths, a hook may still reference a flowtable, exposing it to the packet path and nfnetlink control plane. The fix inserts synchronize_rcu() after unregistering hooks (rcu grace period...

CVE-2026-23357

CVE-2026-23357 affects the Linux kernel can/mcp251x driver. The deadlock occurred when free_irq() was called in the error path of mcp251x_open while mpc_lock was still held, potentially waiting for an IRQ handler. The fix moves free_irq() to after releasing the lock, and sets priv->force_quit ...
