kernel: race condition between HCIUARTSETPROTO and HCIUARTGETPROTO in hci_uart_tty_ioctl
An issue was discovered in drivers/bluetooth/hci_ldisc.c in the Linux kernel 6.2. In hci_uart_tty_ioctl, there is a race condition between HCIUARTSETPROTO and HCIUARTGETPROTO. HCI_UART_PROTO_SET is set before hu->proto is set. A NULL pointer dereference may occur.
A NULL pointer dereference flaw was found in the Linux kernel’s Bluetooth HCI UART driver. This flaw allows a local user to crash the system.
Mitigation: To mitigate this issue, prevent module hci_uart from being loaded. Please see https://access.redhat.com/solutions/41278 for how to blacklist a kernel module to prevent it from loading automatically.

Seth Jenkins discovered that the Linux kernel did not properly perform
address randomization for a per-cpu memory management structure. A local
attacker could use this to expose sensitive information (kernel memory) or
in conjunction with another kernel vulnerability. (CVE-2023-0597)
It was discovered that the IPv6 implementation in the Linux kernel
contained a high rate of hash collisions in connection lookup table. A
remote attacker could use this to cause a denial of service (excessive CPU
consumption). (CVE-2023-1206)
Yu Hao and Weiteng Chen discovered that the Bluetooth HCI UART driver in

CVE-2023-31083 [MEDIUM] CWE-362 GHSA-cv34-v4cf-53pq: An issue was discovered in drivers/bluetooth/hci_ldisc
An issue was discovered in drivers/bluetooth/hci_ldisc.c in the Linux kernel 6.2. In hci_uart_tty_ioctl, there is a race condition between HCIUARTSETPROTO and HCIUARTGETPROTO. HCI_UART_PROTO_SET is set before hu->proto is set. A NULL pointer dereference may occur.
