kernel-3.10.0-1160.80.1.el7

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

* a use-after-free in cls_route filter implementation may lead to privilege escalation (CVE-2022-2588)
* RetBleed Arbitrary Speculative Code Execution with Return Instructions (CVE-2022-23816, CVE-2022-29900)
* Branch Type Confusion (non-retbleed) (CVE-2022-23825)
* Intel: Post-barrier Return Stack Buffer Predictions (CVE-2022-26373)
* Intel: RetBleed Arbitrary Speculative Code Execution with Return Instructions (CVE-2022-29901)

Bug Fix(es):

* lpfc panics in lpfc_els_free_iocb() during port recovery
* mlx5 reports error messages during shutdown then panic with mce

CVE-2022-23816
** RESERVED ** This candidate has been reserved by an organization or individual that will use it when announcing a new security problem. When the candidate has been publicized, the details for this candidate will be provided.
CVE-2022-23825
Aliases in the branch predictor may cause some AMD processors to predict the wrong branch type potentially leading to information disclosure.
CVE-2022-2588
** RESERVED ** This candidate has been reserved by an organization or individual that will use it when announcing a new security problem. When the candidate has been publicized, the details for this candidate will be provided.
CVE-2022-26373
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.
CVE-2022-29900
Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution under certain microarchitecture-dependent conditions.
CVE-2022-29901
Intel microprocessor generations 6 to 8 are affected by a new Spectre variant that is able to bypass their retpoline mitigation in the kernel to leak arbitrary data. An attacker with unprivileged user access can hijack return instructions to achieve arbitrary speculative code execution under certain microarchitecture-dependent conditions.
