Published Jun 21, 2012

HIGHCVSS 2.0
EPSS 0.50%
Description
The robust futex implementation in the Linux kernel before 2.6.28 does not properly handle processes that make exec system calls, which allows local users to cause a denial of service or possibly gain privileges by writing to a memory location in a child process.

Remediation
Red Hat statement
This issue did not affect the Linux kernel as shipped with Red Hat Enterprise Linux 4 as it did not have support for robust futexes. It did not affect Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG as they have the backported fixes. This has been addressed in Red Hat Enterprise Linux 5 via https://rhn.redhat.com/errata/RHSA-2012-0107.html.
