Description OSIDB Bzimport 2025-02-26 03:15:33 UTC 
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.
