CVE-2022-49929

CVE-2022-49929 relates to the Linux kernel RDMA/rxe path. The issue is a use-after-free-like leak in MR handling: rxe_recheck_mr() increments mr ref_cnt and, during RESPST_ERR_RNR, the code must call rxe_put(mr) to drop the extra reference to avoid a warning in __rxe_cleanup. The vulnerability is...
