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...
