Overview

CVE-2024-50161 is a high-severity vulnerability affecting linux linux_kernel. It was published on November 7, 2024 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

bpf: Check the remaining info_cnt before repeating btf fields

When trying to repeat the btf fields for array of nested struct, it

doesn't check the remaining info_cnt. The following splat will be

reported when the value of ret * nelems is greater than BTF_FIELDS_MAX:

------------[ cut here ]------------

UBSAN: array-index-out-of-bounds in ../kernel/bpf/btf.c:3951:49

index 11 is out of range for type 'btf_field_info [11]'
