UBUNTU-CVE-2022-50137

In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Fix a window for use-after-free During a destroy CQ an interrupt may cause processing of a CQE after CQ resources are freed by irdmacqfreersrc. Fix this by moving the call to irdmacqfreersrc after the...

CVE-2022-50137

CVE-2022-50137 (Linux kernel) affects RDMA/irdma by a window for use-after-free during CQ destruction. An interrupt could cause CQE processing after CQ resources are freed by irdma_cq_free_rsrc(). The fix moves irdma_cq_free_rsrc() to run after irdma_sc_cleanup_ceqes() (which executes under cq_lo...
