medium Tenable Self-Hosted Container Security Plugin ID 475086

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: RDMA/mad: Fix receive buffer leak when
 PKey enforcement fails ib_mad_complete_recv() initializes mad_recv_wc->rmpp_list and then runs
 ib_mad_enforce_security() before linking recv_buf onto that list. On failure it calls ib_free_recv_mad(),
 which only walks rmpp_list and frees the ib_mad_private of every buffer found there. As the list is still
 empty at that point, nothing is freed at all. The caller cannot clean up either: ib_mad_recv_done() sets
 recv to NULL right after ib_mad_complete_recv() returns, assuming the MAD layer took ownership of the
 buffer. Every MAD that fails the PKey check therefore leaks one ib_mad_private (about 300 bytes per IB
 port MAD, ~2K for OPA), and a remote node can trigger this repeatedly by sending MADs with a wrong PKey.
 Link recv_buf onto rmpp_list right after the list is initialized, so the error path has something to free.
 (CVE-2026-98354)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.739.5 or later.
