CVE-2025-37960

5.5 · MEDIUM
Published May 20, 2025 linux EPSS 0.18% (7th pctl)

Overview

CVE-2025-37960 is a medium-severity vulnerability affecting linux linux_kernel. It was published on May 20, 2025 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:

memblock: Accept allocated memory before use in memblock_double_array()

When increasing the array size in memblock_double_array() and the slab

is not yet available, a call to memblock_find_in_range() is used to

reserve/allocate memory. However, the range returned may not have been

accepted, which can result in a crash when booting an SNP guest:
