CVE-2026-46105
Description
AI Translation Available
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.
