UBUNTU-CVE-2021-46908

In the Linux kernel, the following vulnerability has been resolved: bpf: Use correct permission flag for mixed signed bounds arithmetic We forbid adding unknown scalars with mixed signed bounds due to the spectre v1 masking mitigation. Hence this also needs bypassspecv1 flag instead of...

CVE-2021-46908

CVE-2021-46908 affects the Linux kernel BPF verifier: the issue stems from using an incorrect permission flag for mixed signed bounds arithmetic. The fix ensures bypass_spec_v1 is used (instead of allow_ptr_leaks) to align with spectre v1 mitigation requirements. The vulnerability has been resolv...
