Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.14.8

Description The issue allows local users to cause a denial of service (memory corruption) or possibly have unspecified other impact by leveraging improper use of pointers in place of scalars in the kernel/bpf/verifier.c file.

Recommendations For versions prior to 4.14.8, update to version 4.14.8 or later to resolve the issue. As a temporary workaround, consider restricting access to the kernel/bpf/verifier.c file to minimize the risk of exploitation.
