CVE-2021-3444

CVE-2021-3444 affects the Linux kernel’s eBPF verifier, where mod32 destination register truncation can be mishandled when the source is known to be zero. This enables a local attacker loading BPF programs to read kernel memory (information disclosure) and potentially perform out-of-bounds writes...

CVE-2021-3444 Linux kernel bpf verifier incorrect mod32 truncation

The bpf verifier in the Linux kernel did not properly handle mod32 destination register truncation when the source register was known to be 0. A local attacker with the ability to load bpf programs could use this gain out-of-bounds reads in kernel memory leading to information disclosure kernel...
