OESA-2025-2766 kernel security update

The Linux Kernel, the operating system core itself. Security Fixes: A transient execution vulnerability in some AMD processors may allow an attacker to infer data in the L1D cache, potentially resulting in the leakage of sensitive information across privileged boundaries.CVE-2024-36357 In the Lin...

hw: L1D Cache Eviction Sampling

A microarchitectural timing flaw was found on some Intel processors. A corner case exists where data in-flight during the eviction process can end up in the “fill buffers” and not properly cleared by the MDS mitigations. The fill buffer contents which were expected to be blank can be inferred usi...

hw: information disclosure on some Intel Atom processors

A potential domain bypass transient execution vulnerability was discovered on some Intel Atom® processors that uses a microarchitectural incidental channel. Currently this channel can reveal supervisor data in the L1 cache and the contents of recent stores. As a consequence, this issue may allow ...

The vulnerability of the way predictor implementation in AMD CPUs’ L1D cache architecture allows a hacker to gain access to memory on the same CPU’s physical core.

The vulnerability of the way predictor’s implementation for first-level cache data on AMD CPUs’ L1D cache relates to the fact that accessing the same memory cell from a different virtual address may cause that cell to be evicted from the L1D cache. Exploiting this vulnerability could allow a remo...

ALPINE-CVE-2018-3646

Systems with microprocessors utilizing speculative execution and address translations may allow unauthorized disclosure of information residing in the L1 data cache to an attacker with local user access with guest OS privilege via a terminal page fault and a side-channel analysis...

UBUNTU-CVE-2018-3646

Systems with microprocessors utilizing speculative execution and address translations may allow unauthorized disclosure of information residing in the L1 data cache to an attacker with local user access with guest OS privilege via a terminal page fault and a side-channel analysis...
