CVE-2026-46200

CVE-2026-46200 affects the Linux kernel SPI MPC52xx driver. The issue stems from improper controller deregistration: the driver may deregister the controller after or without ensuring proper release of resources (interrupts, GPIOs) during driver unbind, risking system instability or resource exha...

CVE-2026-46200 spi: mpc52xx: fix controller deregistration

In the Linux kernel, the following vulnerability has been resolved: spi: mpc52xx: fix controller deregistration Make sure to deregister the controller before disabling and releasing underlying resources like interrupts and gpios during driver unbind...

SUSE CVE-2026-46034

In the Linux kernel, the following vulnerability has been resolved: vfio/cdx: Fix NULL pointer dereference in interrupt trigger path Add validation to ensure MSI is configured before accessing cdxirqs array in vfiocdxsetmsitrigger. Without this check, userspace can trigger a NULL pointer...

CVE-2026-45957

A flaw was found in the Linux kernel's Read-Copy Update RCU mechanism. A missing recursion protection in the rcureadunlock function can lead to an infinite loop, known as a deadloop, when a soft interrupt softirq is triggered. This issue can cause the system to become unresponsive, resulting in a...

CVE-2026-46034

A flaw was found in the Linux kernel's vfio/cdx module. A local user can cause a system crash by improperly configuring Message Signaled Interrupts MSI before they are set up. This can lead to a NULL pointer dereference, resulting in a Denial of Service DoS for the system...
