Technical description
In the Linux kernel, the following vulnerability has been resolved:
scsi: mpt3sas: Avoid freeing unallocated PCIe SGL buffers
_base_release_memory_pools() unconditionally frees every
ioc->pcie_sg_lookup[] entry, including ones the setup loop never
allocated after a partial failure, causing a "bad dma" warning on debug
kernels or a NULL pointer dereference otherwise.
Remediation
Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
