CVE-2022-48675
CVE-2022-48675 is a Linux kernel issue in IB/core involving a nested deadlock between exiting mmap (exit_mmap/__mmu_notifier_release) and a mutex held during ib_umem_odp_map_dma_and_lock. The root cause is a potential deadlock when mmput() is called while umem_mutex is held, triggering a lock in ...
