The vulnerability of the mxser_activate() function in the drivers/tty/mxser.c file of the console TTY support driver for the Linux operating system allows a hacker to cause a service failure.

The vulnerability of the mxseractivate function in the drivers/tty/mxser.c file of the TTY console support driver in the Linux operating system is related to the copying of buffers without checking the size of the input data. Exploiting this vulnerability could allow an attacker to cause a servic...

SUSE CVE-2022-49191

In the Linux kernel, the following vulnerability has been resolved: mxser: fix xmitbuf leak in activate when LSR == 0xff When LSR is 0xff in -activate rather unlike, we return an error. Provided -shutdown is not called when -activate fails, nothing actually frees the buffer in this case. Fix this...
