Answer in brief
CVE-2026-46105 records a High severity (CVSS 7.8) vulnerability in scsi: mpt3sas: Limit NVMe request size to 2 MiB. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 7.8. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
