CVE-2026-46136 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7921: fix a potential clc buffer length underflow The buf_len is used to limit the iterations for retrieving the country power setting and may underflow under certain conditions due to changes in the power table in CLC. This underflow leads to an almost infinite loop or an invalid power setting resulting in driver initialization failure.. EPSS estimates a 0.13% chance of exploitation in the next 30 days.
