kernel: x86: fix user address masking non-canonical speculation issue
A flaw was found in the Linux kernel's handling of user address masking on x86 architectures. This vulnerability, similar to "Meltdown Lite," allows for speculative execution a CPU optimization technique to be exploited due to incorrect handling of non-canonical memory accesses in kernel space. A...

Linux Distros Unpatched Vulnerability : CVE-2020-10768
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - A flaw was found in the Linux Kernel before 5.8-rc1 in the prctl function, where it can be used to enable indirect branch speculation after it has been disabled...
microcode_ctl: From CVEorg collector
New Spectre-v2 attack classes have been discovered within CPU architectures that enable self-training exploitation of speculative execution within the same privilege domain. These novel techniques bypass existing hardware and software mitigations, including IBPB, eIBRS, and BHINO, by leveraging...

Astra Linux – Vulnerability in Linux 6.12
In the Linux kernel, the following vulnerability has been resolved: iouring: prevents opcode speculation. sqe-opcode is used for different tables; ensure that we address this issue to prevent speculation...
Exploiting Inaccurate Branch History in Side-Channel Attacks
Modern out-of-order CPUs heavily rely on speculative execution for performance optimization, with branch prediction serving as a cornerstone to minimize stalls and maximize efficiency. Whenever shared branch prediction resources lack proper isolation and sanitization methods, they may originate...
