CVE-2026-64521

CVE-2026-64521 affects the Linux kernel pinctrl subsystem (meson: amlogic-a4). The deadlock arises when pinconf_pins_show() holds pctldev->mutex while pinctrl_find_gpio_range_from_pin() tries to re-acquire the same mutex; the fix is to use pinctrl_find_gpio_range_from_pin_nolock() to avoid the...

PT-2026-64742

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A deadlock can occur when accessing the pinconf-pins sysfs node. This happens because the pinconf pins show function holds the pctldev-mutex, and the platform driver subsequently calls...

SUSE CVE-2026-46029

In the Linux kernel, the following vulnerability has been resolved: mm/slab: return NULL early from kmallocnolock in NMI on UP On UP kernels !CONFIGSMP, spintrylock is a no-op that unconditionally succeeds even when the lock is already held. As a result, kmallocnolock called from NMI context can...

CVE-2026-46029

A flaw was found in the Linux kernel. In uniprocessor UP kernel configurations, a race condition can occur within the slab memory allocator when kmallocnolock is invoked from a Non-Maskable Interrupt NMI context. This allows the allocator to attempt to acquire a spinlock that is already held,...
