CVE-2025-38646

CVSS v3.1

5.5

Medium

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions: Linux kernel versions 6.6.56-05896-g89f5fb0eb30b and earlier.
Description: A NULL dereference issue existed in the Linux kernel's rtw89 driver related to Wi-Fi functionality. Specifically, a problematic packet received on an unsupported 6 GHz band could lead to a NULL dereference in the rtw89 vif rx stats iter() and rtw89 core cancel 6ghz probe tx() functions. This occurred when the system incorrectly identified a packet as being received on the 6 GHz band, even though the chip did not support it, resulting in a crash.
Recommendations: Linux kernel versions prior to 6.6.56-05896-g89f5fb0eb30b should be updated.
