CVE-2013-7026

CVSS v2.0

4.7

Medium

VectorAV:L/AC:M/Au:N/C:N/I:N/A:C
Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.12.2
Description The issue is related to multiple race conditions in the Linux kernel, specifically in the ipc/shm.c file. This can be exploited by local users through a crafted application that utilizes shmctl IPC RMID operations in conjunction with other shm system calls, potentially leading to a denial of service (use-after-free and system crash) or possibly other unspecified impacts.
Recommendations For Linux kernel versions prior to 3.12.2, update to version 3.12.2 or later to resolve the issue. As a temporary workaround, consider restricting the use of shm system calls to minimize the risk of exploitation.
