CVE-2026-46105

HIGHNVD 7.8

7.8

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.

CVSS v3: 7.8
EG Score: 0.0(none)
EPSS: 1.7%
KEV: Not listed
