What is CVE-2022-50052?
CVE-2022-50052 is a high-severity memory corruption vulnerability in Linux kernel, published on 18 Jun 2025. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
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.
Weakness: CWE-787
