UBUNTU-CVE-2022-50069
In the Linux kernel, the following vulnerability has been resolved: BPF: Fix potential bad pointer dereference in bpfsysbpf The bpfsysbpf helper function allows an eBPF program to load another eBPF program from within the kernel. In this case the argument union bpfattr pointer as well as the insn...
