CVE-2026-68085

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hciuart: clear HCIUARTSENDING when writework is canceled HCIUARTSENDING bit in txstate means writework is pending and blocks queueing it again. Currently this bit is not cleared when canceling the work in hciuartclose,...
