AZL-59264 CVE-2024-26814 affecting package kernel for versions less than 5.15.176.3-3

In the Linux kernel, the following vulnerability has been resolved: vfio/fsl-mc: Block calling interrupt handler without trigger The eventfdctx trigger pointer of the vfiofslmcirq object is initially NULL and may become NULL if the user sets the trigger eventfd to -1. The interrupt handler itself...

DEBIAN-CVE-2024-27437

In the Linux kernel, the following vulnerability has been resolved: vfio/pci: Disable auto-enable of exclusive INTx IRQ Currently for devices requiring masking at the irqchip for INTx, ie. devices without DisINTx support, the IRQ is enabled in requestirq and subsequently disabled as necessary to...

UBUNTU-CVE-2024-26813

In the Linux kernel, the following vulnerability has been resolved: vfio/platform: Create persistent IRQ handlers The vfio-platform SETIRQS ioctl currently allows loopback triggering of an interrupt before a signaling eventfd has been configured by the user, which thereby allows a NULL pointer...

UBUNTU-CVE-2024-26812

In the Linux kernel, the following vulnerability has been resolved: vfio/pci: Create persistent INTx handler A vulnerability exists where the eventfd for INTx signaling can be deconfigured, which unregisters the IRQ handler but still allows eventfds to be signaled with a NULL context through the...

UBUNTU-CVE-2024-26810

In the Linux kernel, the following vulnerability has been resolved: vfio/pci: Lock external INTx masking ops Mask operations through config space changes to DisINTx may race INTx configuration changes via ioctl. Create wrappers that add locking for paths outside of the core interrupt code. In...

CVE-2024-26814

CVE-2024-26814 affects the Linux kernel vfio-fsl-mc driver. The eventfd_ctx trigger pointer for vfio_fsl_mc_irq can be NULL and may become NULL if the trigger is set to -1. The interrupt handler itself is guaranteed to have a valid trigger between request_irq() and free_irq(), but loopback tests ...

CVE-2024-26810 vfio/pci: Lock external INTx masking ops

In the Linux kernel, the following vulnerability has been resolved: vfio/pci: Lock external INTx masking ops Mask operations through config space changes to DisINTx may race INTx configuration changes via ioctl. Create wrappers that add locking for paths outside of the core interrupt code. In...

CVE-2024-26810

CVE-2024-26810 (Linux kernel) concerns the vfio/pci path where masking operations for external INTx were not properly synchronized with INTx configuration changes. The description in the initial document notes a race between config-space changes to DisINTx and ioctl-driven updates to interrupt co...

Linux Kernel Security Vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from a security issue in vfio/pci, where a mask change to DisINTx via configuration space may compete with INTx...
