CVE-2024-27066 virtio: packed: fix unmap leak for indirect desc table

In the Linux kernel, the following vulnerability has been resolved: virtio: packed: fix unmap leak for indirect desc table When usedmaapi and premapped are true, then the dounmap is false. Because the dounmap is false, vringunmapextrapacked is not called by detachbufpacked. if unlikelyvq-dounmap...

CVE-2024-27066

CVE-2024-27066 concerns a Linux kernel vulnerability in virtio packed handling of indirect descriptor tables. When using_dma_api and premapped are true, the code path that performs do_unmap can be skipped, preventing vring_unmap_extra_packed from being invoked during detach_buf_packed. This leave...

Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: The issue is related to an unmap leak for indirect desc tables in the virtio packed functionality. When use dma api and premapped are true, do unmap is false, which prevents vring unma...

kernel: virtio_vdpa: build affinity masks conditionally

A flaw was found in the Linux kernel's virtio vDPA driver. When the number of device queues exceeds the number of CPUs, the createaffinitymasks function triggers a kernel warning in groupcpusevenly. This occurs because the affinity logic assumes CPUs are not fewer than queue groups, which doesn't...

kernel: vdpa: Add queue index attr to vdpa_nl_policy for nlattr length check

An out-of-bounds read vulnerability was found in the Linux kernel's vDPA virtio Data Path Acceleration netlink interface. The vdpanlpolicy structure was missing the nlapolicy entry for the queue index attribute. Without proper validation, parsing netlink messages with this attribute could result ...

kernel: virtio-vdpa: Fix cpumask memory leak in virtio_vdpa_find_vqs()

A memory leak was found in the virtio-vdpa driver. The cpumask allocated by createaffinitymasks is not freed before the function returns, causing a small memory leak each time virtqueues are set up...
