Vector
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Exploitability: 1.8 / Impact: 5.9
Source: 416baaa9-dc9f-4396-8d5f-8c081fb06d67 (Secondary)
Description
In the Linux kernel, the following vulnerability has been resolved:
scsi: mpt3sas: Limit NVMe request size to 2 MiB
The HBA firmware reports NVMe MDTS values based on the underlying drive
capability. However, because the driver allocates a fixed 4K buffer for
the PRP list, accommodating at most 512 entries, the driver supports a
maximum I/O transfer size of 2 MiB.
Limit max_hw_sectors to the smaller of the reported MDTS and the 2 MiB
driver limit to prevent issuing oversized I/O that may lead to a kernel
oops.
