Information disclosure

An information disclosure vulnerability exists on ARM implementations that use speculative execution in control flow via a side-channel analysis, aka "straight-line speculation." To exploit this vulnerability, an attacker with local privileges would need to run a specially crafted application. Th...

CVE-2020-1459

CVE-2020-1459 is a Windows ARM information-disclosure vulnerability tied to speculative-execution side-channel behavior (straight-line speculation). The issue requires local privileges to run a crafted app to exfiltrate data. The provided documents state that Microsoft’s security update bypasses ...

KB4565351: Windows 10 Version 1903 and Windows 10 Version 1909 August 2020 Security Update

The remote Windows host is missing security update 4565351. It is, therefore, affected by multiple vulnerabilities : - A memory corruption vulnerability exists when Windows Media Foundation improperly handles objects in memory. An attacker who successfully exploited the vulnerability could instal...

Intel, ARM, IBM, AMD Processors Vulnerable to New Side-Channel Attacks

It turns out that the root cause behind several previously disclosed speculative execution attacks against modern processors, such as Meltdown and Foreshadow, was misattributed to 'prefetching effect,' resulting in hardware vendors releasing incomplete mitigations and countermeasures. Sharing its...

kernel: Rogue cross-process SSBD shutdown. Linux scheduler logical bug allows an attacker to turn off the SSBD protection.

A logic bug flaw was found in the Linux kernel’s implementation of SSBD. A bug in the logic handling allows an attacker with a local account to disable SSBD protection during a context switch when additional speculative execution mitigations are in place. This issue was introduced when the per...
