Last modified
CVE-2021-46908 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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 bypass_spec_v1 flag instead of allow_ptr_leaks.. EPSS estimates a 0.23% chance of exploitation in the next 30 days.
