kernel: bpf: Fix crash due to out of bounds access into reg2btf_ids.

bpf in linux kernel incorrectly managed register types, leading to out of bounds access and possible kernel crashing when bad pointer gets dereferenced...

The vulnerability of the bpf component in the Linux operating system’s kernel allows a hacker to trigger a service failure.

The vulnerability of the bpf component in the Linux operating system’s kernel is related to a crash due to access beyond the boundaries of reg2btfids. Exploiting this vulnerability can allow an attacker to cause a service failure...
