Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: cpufreq/longhaul: handled NULL policy in longhaulexit The longhaulexit function was calling cpufreqcpuget0 without checking for a NULL policy pointer. On some systems, this could lead to a NULL derefrence and a kernel warning or...

CVE-2026-64372

A flaw was found in the Linux kernel's cpufreq subsystem. This vulnerability, a use-after-free and double-free error, occurs during the two-phase OSC negotiation in the pcccpufreqdoosc function. A local attacker could exploit this memory corruption to cause a denial of service DoS or potentially...

CVE-2026-64377

A flaw was found in the Linux kernel's qcom-cpufreq-hw driver. This vulnerability, a double free, occurs due to incorrect memory handling when a device is detached. Specifically, the system attempts to release memory that is already managed, leading to a potential double free. This can result in...

CVE-2026-64373

The issue CVE-2026-64373 affects the Linux kernel cpufreq subsystem. During system reboot, cpufreq_suspend() is invoked via kernel_restart() where freeze_processes() is not called, allowing CPU hotplug to run concurrently and potentially free governor_data while cpufreq_suspend() accesses it. Thi...

CVE-2026-64372 cpufreq: pcc: fix use-after-free and double free in _OSC evaluation
