CVE-2021-4159

A vulnerability was found in the Linux kernel’s EBPF verifier when handling
internal data structures. Internal memory locations could be returned to
userspace. A local attacker with the permissions to insert eBPF code to the
kernel can use this to leak internal kernel memory details defeating some
of the exploit mitigations in place for the kernel.
