An arbitrary memory r/w access issue was found in the Linux kernel compiled with the eBPF bpf(2) system call (CONFIG_BPF_SYSCALL) support. The issue could occur due to calculation errors in the eBPF verifier module, triggered by user supplied malicious BPF program. An unprivileged user could use this flaw to escalate their privileges on a system. Setting parameter "kernel.unprivileged_bpf_disabled=1" prevents such privilege escalation by restricting access to bpf(2) call.
This module exploits a vulnerability in various ASUS and 3rd party branded utilities. The low level access drivers at the core of these utilities expose dangerous functionality to low privilege processes, a local attacker can read/write arbitrary kernel memory, which can be leveraged to elevate privileges.
