CVE-2022-49426

CVE-2022-49426 : Linux kernel iommu/arm-smmu-v3-sva had a use-after-free when freeing the MM context because arm64_mm_context_put() ran without a held reference. The root cause is not holding a reference to the MM during unpinning, allowing it to be freed prematurely. The fix is to call mmgrab()/...

CVE-2022-49076

CVE-2022-49076 concerns the Linux kernel RDMA/hfi1 subsystem. The issue is a use-after-free in the mm struct lifecycle: under certain conditions (e.g., MPI_Abort), hfi1_mmu_rb_unregister() may drop the last reference to a task mm, freeing it before its final use in hfi1_release_user_pages. This c...
