Summary
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.
