In the Linux kernel, the following vulnerability has been resolved: net: hns3: add VLAN id validation before using Currently, the VLAN id may be used without validation when receive a VLAN configuration mailbox from VF. The length of vlandelfailbmap is BITSTOLONGSVLANNVID. It may cause...

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...
