Doc Type: If docs needed, set a value
Doc Text:
A vulnerability was found in the panfrost_mmu_map_fault_addr() function in the Linux kernel's drm panfrost_mmu.c driver, where improper error handling and cleanup can lead to resource management problems and system instability. This occurs when the shmem_read_mapping_page() or sg_alloc_table_from_pages() functions fail, causing panfrost_mmu_map_fault_addr() to handle the error by freeing any allocated pages prematurely. By calling drm_gem_shmem_put_pages() prematurely, a potential double-free scenario can result, leading to memory corruption or resource leaks.
