GHSA-M29F-9JRM-J49W

Vulnerability from github – Published: 2025-06-18 12:30 – Updated: 2025-11-13 21:31

Details

In the Linux kernel, the following vulnerability has been resolved:

ASoC: Intel: avs: Fix potential buffer overflow by snprintf()

snprintf() returns the would-be-filled size when the string overflows the given buffer size, hence using this value may result in a buffer overflow (although it's unrealistic).

This patch replaces it with a safer version, scnprintf() for papering over such a potential issue.

Severity ?

7.8 (High)
