Published Mar 11, 2024 linux CWE-770 EPSS 0.24% (15th pctl) CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Overview

CVE-2024-26618 is a medium-severity vulnerability affecting linux linux_kernel. It was published on March 11, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. 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:

arm64/sme: Always exit sme_alloc() early with existing storage

When sme_alloc() is called with existing storage and we are not flushing we

will always allocate new storage, both leaking the existing storage and

corrupting the state. Fix this by separating the checks for flushing and

for existing storage as we do for SVE.

Callers that reallocate (eg, due to changing the vector length) should

call sme_free() themselves.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. 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.
