CVE ID : CVE-2024-56756
Published : Dec. 29, 2024, 12:15 p.m. | 7 hours, 47 minutes ago
Description : 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 __nvme_alloc_host_mem 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 dma_free_coherent.
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.
Severity: 0.0 | NA
