Overview

CVE-2024-44966 is a high-severity vulnerability. It was published on September 4, 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:

binfmt_flat: Fix corruption when not offsetting data start

Commit 04d82a6d0881 ("binfmt_flat: allow not offsetting data start")

introduced a RISC-V specific variant of the FLAT format which does

not allocate any space for the (obsolete) array of shared library

pointers. However, it did not disable the code which initializes the

array, resulting in the corruption of sizeof(long) bytes before the DATA

segment, generally the end of the TEXT segment.

Introduce MAX_SHARED_LIBS_UPDATE which depends on the state of

CONFIG_BINFMT_FLAT_NO_DATA_START_OFFSET to guard the initialization of

the shared library pointer region so that it will only be initialized

if space is reserved for it.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
