Last modified

CVE-2017-17862 is a vulnerability of currently unknown severity. kernel/bpf/verifier.c in the Linux kernel through 4.14.8 ignores unreachable code, even though it would still be processed by JIT compilers. This behavior, also considered an improper branch-pruning logic issue, could possibly be used by local users for denial of service.. EPSS estimates a 0.44% chance of exploitation in the next 30 days.
