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

Description The issue allows local users to cause a denial of service, potentially resulting in memory corruption, by leveraging incorrect BPF RSH signed bounds calculations in the kernel/bpf/verifier.c file. This could possibly have other unspecified impacts.

Recommendations For Linux kernel versions through 4.14.8, update to a version later than 4.14.8 to resolve the issue. As a temporary workaround, consider restricting access to the BPF RSH functionality until a patch is available.
