CVSS v3.1

5.5

Média

VetorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.14.9
Description The issue is related to the Linux kernel's handling of unreachable code in the kernel/bpf/verifier.c component. This behavior is also considered an improper branch-pruning logic issue. It could be used by local users to cause a denial of service. The estimated number of potentially affected devices is not specified.
Recommendations For Linux kernel versions prior to 4.14.9, update to version 4.14.9 or later to resolve the issue. As a temporary workaround, consider restricting access to the kernel/bpf/verifier.c component to minimize the risk of exploitation.
