CVE-2026-31771

A flaw was found in the Linux kernel's Bluetooth subsystem. A remote attacker could exploit a missing bounds check by sending a specially crafted, short Bluetooth Host Controller Interface HCI event frame. This could lead to a buffer overflow, potentially allowing the attacker to cause a denial o...

CVE-2026-43018

A flaw was found in the Linux kernel's Bluetooth component. This Use-After-Free UAF vulnerability arises from insufficient locking during hciconn lookup and access within the hcileremoteconnparamreqevt function. An attacker could potentially exploit this to cause a system crash or execute arbitra...

CVE-2026-31754

In the Linux kernel, the following vulnerability has been resolved: usb: cdns3: gadget: fix state inconsistency on gadget init failure When cdns3gadgetstart fails, the DRD hardware is left in gadget mode while software state remains INACTIVE, creating hardware/software state inconsistency. When...

EUVD-2026-26618

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hciconn: fix potential UAF in setcigparamssync hciconn lookup and field access must be covered by hdev lock in setcigparamssync, otherwise it's possible it is freed concurrently. Take hdev lock to prevent hciconn from...

CVE-2026-31754

The CVE-2026-31754 issue affects the Linux kernel’s USB DRD/CDNS3 gadget path. When cdns3_gadget_start() fails, the DRD hardware remains in gadget mode while software state is INACTIVE, causing hardware/software state inconsistency. This can lead to a failed host-mode switch via sysfs (role switc...
