CVE-2026-31391

A flaw was found in the Linux kernel's atmel-sha204a component. This issue arises when the system attempts to allocate memory, and that allocation fails. If not properly handled, a resource counter, tfmcount, is not correctly decremented, leading to a resource leak. This can be exploited by a loc...

CVE-2026-23466

A flaw was found in the drm/xe component of the Linux kernel. This vulnerability involves insufficient protection of Graphics Translation Table GGTT Memory-Mapped I/O MMIO access. When the driver fails to load or during certain cleanup operations, the system's memory access protection is...

CVE-2026-31399

A flaw was found in the Linux kernel's nvdimm/bus component. During asynchronous device initialization, if the deviceadd function fails in ndasyncdeviceregister, a use-after-free vulnerability can occur. This happens because the device's reference count drops to zero before the parent pointer is...

CVE-2026-23466

In the Linux kernel, the following vulnerability has been resolved: drm/xe: Open-code GGTT MMIO access protection GGTT MMIO access is currently protected by hotplug drmdeventer, which works correctly when the driver loads successfully and is later unbound or unloaded. However, if driver load fail...
