CVE-2021-34866

The connected sources confirm CVE-2021-34866 affects Linux Kernel 5.14-rc3. Root cause: improper validation of user-supplied eBPF programs leading to a type confusion condition in the kernel’s eBPF handling. Impact: local privilege escalation and potential arbitrary code execution in kernel conte...

UBUNTU-CVE-2022-0264

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 som...
