CVE-2026-90008 scsi: megaraid_sas: Limit NVMe request size to the PRP chain frame

In the Linux kernel, the following vulnerability has been resolved: scsi: megaraidsas: Limit NVMe request size to the PRP chain frame megasasmakeprpnvme builds a command's PRP list in cmd-sgframe, a DMA pool buffer of instance-maxchainframesz bytes, spending one entry per NVMe page of the transfe...

CVE-2026-90008

The Linux kernel megaraid_sas driver contains a buffer overflow in megasas_make_prp_nvme(), which builds an NVMe PRP list in a fixed-size DMA pool buffer (cmd->sg_frame) without checking bounds. After commit 9b8b84879d4a raised BLK_DEF_MAX_SECTORS_CAP from 1280 KiB to 4 MiB, the required list ...

UBUNTU-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 5...
