CVE-2026-68370

CVE-2026-68370 affects the Linux kernel USB gadget dummy_hcd path. A race condition reuses a shared usb_request (fifo_req) before its completion callback finishes, allowing overwriting of the callback pointer and causing a general protection/page fault in dummy_timer. The mitigation adds a fifo_r...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: usb:dwc2: Fixed a memory leak in dwc2hcdinit. usbcreatehcd will allocate memory for hcd, and we should call usbputhcd to free that memory when platformgetresource fails—this prevents the memory leak. The code has been modified to...
