linux-spawning-race-condition (17151) The risk level is classified as MediumMedium Risk

Description:

Linux kernel could allow a local attacker to obtain sensitive information, caused by a race condition with the cmdline node when a process is spawning. A local unauthorized attacker could use this vulnerability to read a process's environment variables.


Consequences:

Obtain Information

Remedy:

For Debian GNU/Linux:
Refer to DSA-1018-2 for patch, upgrade, or suggested workaround information. See References.

For Gentoo Linux:
Upgrade to the latest version of kernel, as listed in GLSA 200408-24. See References.

For Ubuntu Linux:
