In the Linux kernel, the following vulnerability has been resolved: gpio: Prevent potential speculation leaks in gpiodevicegetdesc The userspace may trigger a speculative read of an address outside the gpio descriptor array. Users can do this by calling gpioioctl with an offset that is out of...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In 64-bit versions of the Linux kernel, Copyfromuser does not implement uaccessbeginnospec, which allows a user to bypass the “accessok” check and pass a kernel pointer to copyfromuser. This would enable an attacker to leak sensitive information. We recommend upgrading beyond commit...

CVE-2026-72428

Summary: This CVE concerns the Linux kernel’s BPF Spectre v4 sanitization logic. The root cause is in check_stack_write_fixed_off(), which computes the byte slot incorrectly (-off - 1) and records writes in slot_type[] using (slot - i) % BPF_REG_SIZE. The sanitization pre-check used slot_type[i],...
