Description

In the Linux kernel, the following vulnerability has been resolved: scsi: mpi3mr: Fix issues in mpi3mr_get_all_tgt_info() The function mpi3mr_get_all_tgt_info() has four issues: 1) It calculates valid entry length in alltgt_info assuming the header part of the struct mpi3mr_device_map_info would equal to sizeof(u32). The correct size is sizeof(u64). 2) When it calculates the valid entry length kern_entrylen, it excludes one entry by subtracting 1 from num_devices. 3) It copies num_device by
