CVE-2022-48675 IB/core: Fix a nested dead lock as part of ODP flow
In the Linux kernel, the following vulnerability has been resolved: IB/core: Fix a nested dead lock as part of ODP flow Fix a nested dead lock as part of ODP flow by using mmputasync. From the below call trace 1 can see that calling mmput once we have the umemodp-umemmutex locked as required by...
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 ...
