Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1, and Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: ACPI: PAD: fixed a crash in exitroundrobin The kernel occasionally crashes in cpumaskclearcpu, which is called within exitroundrobin. This occurs when executing clearbitnr, addr with nr set to 0xffffffff. In such cases, the...

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

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...

CVE-2026-93112 bpf: Require a BPF cpumask for bpf_cpumask_populate()

In the Linux kernel, the following vulnerability has been resolved: bpf: Require a BPF cpumask for bpfcpumaskpopulate bpfcpumaskpopulate writes to its destination with bitmapcopy, but the destination is typed as struct cpumask . That allows the verifier to accept borrowed cpumask pointers returne...

CVE-2026-93112

CVE-2026-93112 affects the Linux kernel BPF subsystem. The vulnerability is in bpf_cpumask_populate() , whose destination parameter is typed as struct cpumask * instead of struct bpf_cpumask *. This type mismatch allows the BPF verifier to accept borrowed, read-only cpumask pointers (e.g., from s...
