CVE-2026-98655

A flaw was found in the Linux kernel. An unprivileged local user could exploit this vulnerability to cause an information disclosure, bypassing Kernel Address Space Layout Randomization KASLR, a security feature that randomizes kernel memory addresses to hinder exploitation. By opening performanc...

CVE-2026-93181

A flaw was found in the Linux kernel's uncore performance monitoring unit. An incorrect ordering of internal function calls during CPU online and offline operations can prevent the uncore box from being properly initialized or de-initialized. This mismanagement of resources could lead to system...
