kernel: Kernel: Denial of Service in amdgpu driver due to improper interrupt handling

A flaw was found in the Linux kernel's amdgpu graphics driver. A local user with low privileges could exploit this vulnerability due to the improper use of the amdgpuirqput function within the gmcv100hwfini component. This flaw leads to a call trace, which can result in a system crash and a Denia...

CVE-2024-26814

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...

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...

CVE-2024-26788 dmaengine: fsl-qdma: init irq after reg initialization

In the Linux kernel, the following vulnerability has been resolved: dmaengine: fsl-qdma: init irq after reg initialization Initialize the qDMA irqs after the registers are configured so that interrupts that may have been pending from a primary kernel don't get processed by the irq handler before ...

DEBIAN-CVE-2024-26776

In the Linux kernel, the following vulnerability has been resolved: spi: hisi-sfc-v3xx: Return IRQNONE if no interrupts were detected Return IRQNONE from the interrupt handler when no interrupt was detected. Because an empty interrupt will cause a null pointer error: Unable to handle kernel NULL...

CVE-2021-47169

CVE-2021-47169 : In the Linux kernel, the serial rp2 driver could NULL-dereference if a firmware load via request_firmware_nowait occurred before ports were initialized. The fix was to use a synchronous firmware load (request_firmware) during rp2_probe to ensure interrupts are not handled before ...

CVE-2021-47153

In the Linux kernel, the following vulnerability has been resolved: i2c: i801: Don't generate an interrupt on bus reset Now that the i2c-i801 driver supports interrupts, setting the KILL bit in a attempt to recover from a timed out transaction triggers an interrupt. Unfortunately, the interrupt...

CVE-2021-47153

CVE-2021-47153 involves the Linux kernel i2c: i801 driver. The issue occurs when a KILL-recover/bus-reset process triggers an interrupt that the i801_isr cannot handle, potentially causing an out-of-bounds memory access in block transactions. The connected MiracleLinux advisories (AXSA) reference...

SUSE CVE-2023-52559

In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Avoid memory allocation in iommususpend The iommususpend syscore suspend callback is invoked with IRQ disabled. Allocating memory with the GFPKERNEL flag may re-enable IRQs during the suspend callback, which can cause...

DEBIAN-CVE-2023-52567

In the Linux kernel, the following vulnerability has been resolved: serial: 8250port: Check IRQ data before use In case the leaf driver wants to use IRQ polling irq = 0 and IIR register shows that an interrupt happened in the 8250 hardware the IRQ data can be NULL. In such a case we need to skip...
