CVE-2013-7026: Multiple race conditions in ipc/shm.c in the Linux kernel before 3.12.2 allow local users to cause a denial...

Security readout for executives and security teams

CVE-2013-7026 is an old Linux kernel shared-memory bug. A local user could run a crafted application that races shared-memory removal operations and potentially crash the system. The public record does not show remote exploitation or confirmed active exploitation. Exposure is most relevant to systems running Linux kernels before 3.12.2 or distribution kernels that did not receive the corresponding vendor fix. Risk is higher on multi-user hosts, shared compute, or systems allowing untrusted local code execution. Treat this as a patch hygiene and local denial-of-service issue. It is not supported as actively exploited in the provided sources, but vulnerable multi-user Linux systems could be crashed by local users. Prioritize remaining legacy kernels and shared platforms. Mitigation focus: Apply vendor kernel updates that address CVE-2013-7026.; Confirm Ubuntu systems received relevant USN-2070-1 or USN-2075-1 updates.; For upstream kernels, move to a fixed kernel including the 3.12.2 change..
