Linux kernel is the kernel used by the Linux Foundation’s open source operating system Linux. A denial of service vulnerability exists in the Linux Kernel VirtIO Bluetooth driver, which is caused by a memory leak in the VirtIO Bluetooth driver memory leak in driver/Bluetooth/VirtIO_bt.c. A local attacker can exploit this vulnerability to cause a denial of service condition by sending a constructed frame to the driver interface.
