CVE-2026-63821

A flaw was found in the Linux kernel's rtw88 Wi-Fi driver for USB. When the rtwusbwriteport function fails to submit a USB Request Block URB, such as during a device disconnect or out of memory conditions, the system does not properly free allocated memory. This oversight leads to memory leaks of...
