Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified)

Description: The issue is related to the bpf component of the Linux kernel and involves errors in reading beyond the boundaries of a memory buffer. This can potentially allow an attacker to cause a denial of service. The problem arises after a specific commit when non-VM ALLOC mappings are marked as accessible, leading to out-of-bound access complaints by KASAN. The solution involves using VM MAP instead of VM ALLOC for the ringbuf area, as it is created by mapping allocated pages.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
