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.
Tp-link EAP Controller does not handle privilege management correctly so a non privileged user can execute privileged actions. This module will try to change the device's settings and enable ssh in order to take control of the managed Access Points.
