CVE-2026-46105

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.
