kernel: Linux kernel: BPF verifier log truncation via crafted user input

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF verifier log. A local user can exploit this by providing excessively long BPF Type Format BTF names or BTF.ext source code line strings. This can lead to the truncation of a single verifier log line, potentially obscuring important...
