Scope of this Security Bulletin:
As with previous related CVEs (Spectre/Meltdown variants), we plan to address these vulnerabilities as part of the regular update cycles for the impacted products. These vulnerabilities have been given the code name "SWAPGS Attack".
For virtual appliances including instances running in the cloud, make sure that you have applied the vendor fixes to the virtual environment they are running in.
CVE-2019-1125
A Spectre gadget was found in the Linux kernel's implementation of system interrupts. An attacker with local access could use this information to reveal private data through a Spectre like side channel.

All Security Bulletins are published on our Knowledge Center. Security Bulletins are retired (removed) once a product is both End of Sale and End of Support (End of Life).
How do I report a product vulnerability to you?
If you have information about a security issue or vulnerability with a product, follow the instructions provided in KB95563 - Report a vulnerability.
How do you respond to this and any other reported security flaws?
Our key priority is the security of our customers. If a vulnerability is found within any of our software or services, we work closely with the relevant security software development team to ensure the rapid and effective development of a fix and communication plan.
We only publish Security Bulletins if they include something actionable such as a workaround, mitigation, version update, or hotfix. Otherwise, we would simply be informing the hacker community that our products are a target, putting our customers at greater risk. For products that are updated automatically, a non-actionable Security Bulletin might be published to acknowledge the discoverer.
