Securing systems against Retbleed
Intel and AMD released software updates to address the recently disclosed Retbleed speculative execution attack, disclosed earlier this week.

Lenovo fixed three bugs impacting more than 70 products, including ThinkBook systems. The CVEs, tracked as CVE-2022-1890, CVE-2022-1891, and CVE-2022-1892, can be abused for code execution in a way that can lead to interruption and hijacking of the operations systems’ execution flow while blocking some important security features.
