CVE-2022-49671
Estado: ModificadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
RDMA/cm: Fix memory leak in ib_cm_insert_listen
cm_alloc_id_priv() allocates resource for the cm_id_priv. When cm_init_listen() fails it doesn't free it, leading to memory leak.
Add the missing error unwind.
