CVE-2026-74488

A flaw was found in the Linux kernel's mwifiex Wi-Fi driver. When parsing Tunneled Direct Link Setup TDLS frames within an Aggregated MAC Service Data Unit A-MSDU, the driver incorrectly uses the length of the parent frame instead of the subframe. This error can lead to a use-after-free...
