Fellow Linux admins-

Spectre vulnerabilities are nothing new, but apparently, for those of us with Snapdragon processors in our devices, Qualcomm didn't learn from years of past experience in other processors and, until recently, had not provided patches to the mainline kernel. Spectre exploits the speculative execution feature of CPUs to trigger the execution of malicious code that reads secret data.

It's a pretty sophisticated attack that has to be fixed in software. Read on to learn what the top Linux community members are doing to improve communications between CPU vendors and the community. 

You'll also learn about a critical Python memory exhaustion vulnerability, CVE-2024-12254, that could result in performance degradation, unresponsive behaviors, or complete crashes.
