CVE-2024-56756: nvme-pci: fix freeing of the HMB descriptor table

Published Dec 29, 2024
·
Updated

In the Linux kernel, the following vulnerability has been resolved:

nvme-pci: fix freeing of the HMB descriptor table

The HMB descriptor table is sized to the maximum number of descriptors that could be used for a given device, but nvmeallochostmem could break out of the loop earlier on memory allocation failure and end up using less descriptors than planned for, which leads to an incorrect size passed to dmafreecoherent.

In practice this was not showing up because the number of descriptors tends to be low and the dma coherent allocator always allocates and frees at least a page.
