kernel: possible race condition in drivers/tty/tty_buffers.c

An out-of-bounds read flaw was found in the Linux kernel’s TeleTYpe subsystem. The issue occurs in how a user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory in the flushtoldisc function. This flaw allows a local user to crash the...

An issue was discovered in the Linux kernel through 6.2.0-rc2. drivers/tty/vcc.c has a race condition and resultant use-after-free if a physically proximate attacker removes a VCC device while calling open() aka a race condition between vcc_open() and vcc_remove().

...

The vulnerability in the driver/tty/vcc.c component of the Linux operating system’s kernel allows a attacker to compromise the integrity and accessibility of protected information.

The vulnerability in the drivers/tty/vcc.c component of the Linux operating system’s kernel arises due to synchronization errors when using a shared resource. Exploiting this vulnerability can allow an attacker to compromise the integrity and accessibility of protected information...
