CVE-2023-52621

CVE-2023-52621: In the Linux kernel, a fix was added to bpf map helpers (bpf_map_lookup_elem, bpf_map_update_elem, bpf_map_delete_elem) to check rcu_read_lock_trace_held() before use when running sleepable BPF programs. The vulnerability arises when sleepable BPF programs manipulate BPF maps unde...

Linux kernel BPF Map Put Use-After-Free

The vulnerability of the bpfmapput function in the kernel/bpf/syscall.c module of the Linux operating system is related to the use of memory after it is freed. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and accessibility of the protected...

Linux kernel BPF Map Free Deferred Heap Buffer Overflow DoS

The vulnerability of the bpfmapfreedeferred function in the kernel/bpf/syscall.c module of the Linux operating system is related to the use of memory after it is freed due to concurrent access to resources race condition. Exploiting this vulnerability could allow an attacker to compromise the...
