Overview

CVE-2024-26795 is a high-severity vulnerability. It was published on April 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:

riscv: Sparse-Memory/vmemmap out-of-bounds fix

Offset vmemmap so that the first page of vmemmap will be mapped

to the first page of physical memory in order to ensure that

vmemmap’s bounds will be respected during

pfn_to_page()/page_to_pfn() operations.

The conversion macros will produce correct SV39/48/57 addresses

for every possible/valid DRAM_BASE inside the physical memory limits.
