CVE-2023-53857

CVE-2023-53857: Linux kernel BPF local storage fix. The issue arises when a bpf local storage update path acquires a local_lock while a raw_spin_lock is held, potentially enabling an unsafe memory allocation context in tracing. The patch ensures kzalloc occurs before acquiring the lock (pre-raw_s...

CVE-2023-53836

Summary (CVE-2023-53836): In the Linux kernel, a race condition can occur in bpf/sockmap code affecting skb refcnt after locking changes. The backlog path may still hold a reference to a skb that userspace has already consumed (skb_dequeue) and freed, leading to a potential use-after-free. The fi...
