SUSE CVE-2026-97904

In the Linux kernel, the following vulnerability has been resolved: cpufreq: initialize policy rwsem before sysfs publication cpufreqpolicyalloc initializes policy-rwsem after kobjectinitandadd has created the policy sysfs directory and its default attributes. A sysfs access can therefore reach a...

SUSE CVE-2026-97905

In the Linux kernel, the following vulnerability has been resolved: cpufreq: zero-initialize policy cpumask before sysfs publication cpufreqpolicyalloc allocates policy-cpus with alloccpumaskvar, i.e. without GFPZERO, unlike the sibling relatedcpus and realcpus masks. With CONFIGCPUMASKOFFSTACK=y...

CVE-2026-97905

A flaw was found in the Linux kernel's CPU frequency scaling cpufreq subsystem. When creating a frequency policy, the kernel exposes system control files sysfs attributes before the CPU mask memory is zero-initialized. A local user could exploit this race condition by accessing these sysfs...

CVE-2026-97904

A flaw was found in the Linux kernel's CPU frequency scaling cpufreq subsystem. A race condition occurs because an internal synchronization lock is initialized only after its system filesystem sysfs entries are made accessible. A local user accessing these sysfs attributes during policy allocatio...

CVE-2026-97905

The Linux kernel contains a vulnerability in the cpufreq component where policy->cpus is allocated without being zero-initialized when CONFIG_CPUMASK_OFFSTACK=y is enabled. Because alloc_cpumask_var() does not guarantee zeroing, the bitmap may contain garbage data from the slab allocator. This...
