The vulnerability in the implementation of the HCI driver for Bluetooth on Linux operating systems allows a hacker to cause a service failure.

The vulnerability in the implementation of the HCI driver Bluetooth kernel for the Linux operating system is related to the assignment of a zero pointer in the functions min,maxkeysizeset in the net/bluetooth/hcidebugfs.c module. Exploiting this vulnerability could allow a malicious actor to caus...

A race condition was found in the Linux kernel's net/bluetooth in sniffmin,maxintervalset function. This can result in a bluetooth sniffing exception issue, possibly leading denial of service...

kernel: Kernel: NULL pointer dereference in Intel GVT-g debugfs during device removal

A flaw was found in the Linux kernel's Intel GVT-g Graphics Virtualization Technology debugfs component. When a device is removed through unbinding, the intelgvtdebugfsclean function may attempt to access a debugfs root that has already been deallocated, leading to a NULL pointer dereference. A...
