CVE-2026-98762

The Linux kernel contains a vulnerability in the dwc2 USB controller driver. Specifically, the dwc2_hcd_free() function deletes the wakeup timer only after freeing host-owned state, which can lead to issues because timer_delete() does not synchronize callbacks or prevent re-queuing. This allows d...
