Linux kernel Bluetooth hci_sockbind Privilege Escalation

The vulnerability of the hcisockbind function in the net/bluetooth/hcisock.c module of the Linux kernel’s Bluetooth subsystem is related to the reallocation of previously freed memory. Exploiting this vulnerability can allow an attacker to gain increased privileges or cause service failures...

Linux Bluetooth btusb_disconnect() Buffer Overflow

The vulnerability of the btusbdisconnect function in the drivers/bluetooth/btusb.c module of the Linux Bluetooth device driver framework is related to the reutilization of previously freed memory. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity,...
