The vulnerability of the btf_func_proto_check() function in the kernel/bpf/btf.c module, which supports the BPF interpreter of the Linux operating system, allows a hacker to trigger a service failure.

The vulnerability of the btffuncprotocheck function in the kernel/bpf/btf.c module, which is part of the Linux kernel’s BPF support, relates to incorrect checking of the specified data type for input parameters. Exploiting this vulnerability could allow an attacker to trigger a service failure...
