CVE-2022-26373

Published: 18 August 2022

Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access.

From the Ubuntu Security Team

Pawan Kumar Gupta, Alyssa Milburn, Amit Peled, Shani Rehana, Nir Shildan and Ariel Sabba discovered that some Intel processors with Enhanced Indirect Branch Restricted Speculation (eIBRS) did not properly handle RET instructions after a VM exits. A local attacker could potentially use this to expose sensitive information.
