UBUNTU-CVE-2023-31083

An issue was discovered in drivers/bluetooth/hcildisc.c in the Linux kernel 6.2. In hciuartttyioctl, there is a race condition between HCIUARTSETPROTO and HCIUARTGETPROTO. HCIUARTPROTOSET is set before hu-proto is set. A NULL pointer dereference may occur...

Linux kernel 代码问题漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A denial of service vulnerability exists in Linux kernel version 6.2, which originates from a race condition between HCIUARTSETPROTO and HCIUARTGETPROTO in hciuartttyioctl in...

GSD-2022-1007295 Bluetooth: hci_{ldisc,serdev}: check percpu_init_rwsem() failure

Bluetooth: hcildisc,serdev: check percpuinitrwsem failure This is an automated ID intended to aid in discovery of potential security vulnerabilities. The actual impact and attack plausibility have not yet been proven. This ID is fixed in Linux Kernel version v5.10.150 by commit...

kernel: use-after-free in drivers/bluetooth/hci_ldisc.c

A flaw was found in the Linux kernel's implementation of the HCI UART driver. A local attacker with access permissions to the Bluetooth device can issue an ioctl, which triggers the hciuartsetproto function in drivers/bluetooth/hcildisc.c. The flaw in this function can cause memory corruption or ...

Buffer Overflows

A race condition flaw, leading to heap-based buffer overflows, was found in the way the Linux kernel's NTTY line discipline LDISC implementation handled concurrent processing of echo output and TTY write operations originating from user space when the underlying TTY driver was PTY. An unprivilege...

kernel: pty layer race condition on tty ldisc shutdown.

A flaw was discovered in the way the Linux kernel's TTY subsystem handled the tty shutdown phase. A local, unprivileged user could use this flaw to cause denial of service on the system by holding a reference to the ldisc lock during tty shutdown, causing a deadlock...
