CVE-2025-37896

5.5 · MEDIUM
Published May 20, 2025 linux CWE-369 EPSS 0.16% (6th pctl)

Overview

CVE-2025-37896 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:

spi: spi-mem: Add fix to avoid divide error

For some SPI flash memory operations, dummy bytes are not mandatory. For

example, in Winbond SPINAND flash memory devices, the `write_cache` and

`update_cache` operation variants have zero dummy bytes. Calculating the

duration for SPI memory operations with zero dummy bytes causes

a divide error when `ncycles` is calculated in the

spi_mem_calc_op_duration().

Add changes to skip the 'ncylcles' calculation for zero dummy bytes.

Following divide error is fixed by this change:

Oops: divide error: 0000 [#1] PREEMPT SMP NOPTI
