The tty_open function in drivers/tty/tty_io.c in the Linux kernel before 3.1.1 mishandles a driver-lookup failure, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via crafted access to a device file under the /dev/pts directory.

CVE-2011-5321 [MEDIUM] GHSA-w32m-rx9f-gjv3: The tty_open function in drivers/tty/tty_io
The tty_open function in drivers/tty/tty_io.c in the Linux kernel before 3.1.1 mishandles a driver-lookup failure, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via crafted access to a device file under the /dev/pts directory.

CVE-2011-5321 [MEDIUM] Kernel: tty: driver reference leakage in tty_open
Kernel: tty: driver reference leakage in tty_open
The tty_open function in drivers/tty/tty_io.c in the Linux kernel before 3.1.1 mishandles a driver-lookup failure, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via crafted access to a device file under the /dev/pts directory.
A NULL pointer dereference flaw was found in the way the Linux kernel's virtual console implementation handled reference counting when accessing pseudo-terminal device files (/dev/pts/*). A local, unprivileged attacker could use this flaw to crash the system.
Statement: This issue does not affect the versions of the kernel package as shipped with
Red Hat Enterprise Linux 5, 7 and Red Hat Enterprise MRG 2.
