MediumMetricsAV:L/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 4.4.1
Description
A race condition in the
tty ioctl function in drivers/tty/tty io.c may allow local users to obtain sensitive information from kernel memory or cause a denial of service, such as a use-after-free condition and system crash, by making a TIOCGETD ioctl call during processing of a TIOCSETD ioctl call.Recommendations
For Linux kernel versions prior to 4.4.1, update to version 4.4.1 or later to resolve the issue.
As a temporary workaround, consider restricting access to the
tty ioctl function to minimize the risk of exploitation. Found an issue in the description? Have something to add? Feel free to write us 👾
