CVE-2022-49764

CVE-2022-49764 (Linux kernel) : A vulnerability in BPF raw tracepoint handling allows a BPF program to recursion-trigget the same tracepoint via bpf_trace_printk, causing spinlock contention paths to recurse and potentially affecting tracing by taking the slow path. Root cause: a BPF program atta...
