CVE-2023-53198

CVE-2023-53198 affects the Linux kernel raw socket handling (net/ipv4/raw.c). The vulnerability is a NULL dereference in raw_get_next(), triggered by races where a socket in one netns is freed while another thread iterates SOCK_RAW sockets. The root cause involves using RCU-based iteration with h...

CVE-2025-39749

The CVE-2025-39749 issue is in the Linux kernel’s RCU read-side handling: when IRQ work is used (CONFIG_IRQ_WORK=y) and rcu_read_unlock() runs in an interrupts-disabled region, irq-work can interrupt rcu_read_unlock_special(), creating a data race on the per-CPU defer_qs_iw_pending field. The fix...
