kernel: dmaengine: idxd: Fix possible Use-After-Free in irq_process_work_list

A vulnerability was found in the Linux kernel's DMA engine component in the irqprocessworklist function. A possible use-after-free condition can occur during list iteration, which is because a descriptor may be freed while another thread is reusing it, potentially leading to access to freed memor...

kernel: RDMA/irdma: Fix KASAN issue with tasklet

In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Fix KASAN issue with tasklet KASAN testing revealed the following issue assocated with freeing an IRQ. 50006.466686 Call Trace: 50006.466691 50006.489538 dumpstack+0x5c/0x80 50006.493475...

kernel: iommu/arm-smmu: Use the correct type in nvidia_smmu_context_fault()

In the Linux kernel, the following vulnerability has been resolved: iommu/arm-smmu: Use the correct type in nvidiasmmucontextfault This was missed because of the function pointer indirection. nvidiasmmucontextfault is also installed as a irq function, and the 'void ' was changed to a struct...

kernel: regmap-irq: Fix out-of-bounds access when allocating config buffers

An off-by-one style bug exists in regmapaddirqchipfwnode where the allocation loop uses numconfigregs instead of numconfigbases as its termination condition. When numconfigregs exceeds numconfigbases, memory beyond the allocated row pointer array gets overwritten. KASAN caught this corruption...

CVE-2024-50192

In the Linux kernel, the following vulnerability has been resolved: irqchip/gic-v4: Don't allow a VMOVP on a dying VPE Kunkun Jiang reported that there is a small window of opportunity for userspace to force a change of affinity for a VPE while the VPE has already been unmapped, but the...

The vulnerability of the vfio component in the Linux operating system’s kernel allows a attacker to trigger a Denial-of-Service Attack (DoS).

The vulnerability of the vfio component in the Linux operating system’s kernel is related to improper error handling in the vfiofslmcsetirqtrigger function. Exploiting this vulnerability can allow an attacker to trigger a Denial-of-Service Attack DoS...
