SCP7-305 : Security Advisory - linux - CVE-2015-7550

Created: Feb 13, 2016    Updated: Sep 8, 2018
Resolved Date: Apr 15, 2016
Found In Version: 7.0.0.12
Fix Version: 7.0.0.15
Severity: Standard
Applicable for: Wind River Linux 7
Component/s: Kernel

Description

The keyctl_read_key function in security/keys/keyctl.c in the Linux kernel before 4.3.4 does not properly use a semaphore, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a crafted application that leverages a race condition between keyctl_revoke and keyctl_read calls.
