| Wade Mealing | 2022-01-14 05:01:05 UTC | Doc Text | A vulnerability was found in Linux kernels EBPF verifier when handling internal data structures. Internal memory locations could be returned to userspacec. 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. | |
