kernel: Bluetooth: MGMT: Fix possible UAFs

A flaw was found in the Linux kernel’s Bluetooth management subsystem net/bluetooth/mgmt.c. The mgmtpending structure may be freed while still being processed, or remain on the pending command list, which allows a use-after-free or double-free scenario. An attacker with local access to the system...

kernel: usb: dwc3: Fix race condition between concurrent dwc3_remove_requests() call paths

A use-after-free vulnerability was found in the DWC3 USB controller driver in the Linux kernel. Multiple unsynchronized execution paths can invoke dwc3removerequests concurrently, leading to premature freeing of USB requests. When one path frees requests while another is still processing them, a...
