Overview

CVE-2023-52790 is a high-severity vulnerability. It was published on May 21, 2024 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, 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:

swiotlb: fix out-of-bounds TLB allocations with CONFIG_SWIOTLB_DYNAMIC

Limit the free list length to the size of the IO TLB. Transient pool can be

smaller than IO_TLB_SEGSIZE, but the free list is initialized with the

assumption that the total number of slots is a multiple of IO_TLB_SEGSIZE.

As a result, swiotlb_area_find_slots() may allocate slots past the end of

a transient IO TLB buffer.

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.
