high Tenable Self-Hosted Container Security Plugin ID 471130

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/irdma: Fix double free related to
rereg_user_mr If IB_MR_REREG_TRANS is set during rereg_user_mr, the umem will be released and a new one
will be allocated in irdma_rereg_mr_trans. If any step of irdma_rereg_mr_trans fails after the new umem is
allocated, it releases the umem, but does not set iwmr->region to NULL. The problem is that this failure
is propagated to the user, who will then call ibv_dereg_mr (as they should). Then, the dereg_mr path will
see a non-NULL umem and attempt to call ib_umem_release again. Fix this by setting iwmr->region to NULL
after ib_umem_release. Fixed: 5ac388db27c4 ("RDMA/irdma: Add support to re-register a memory region")
(CVE-2026-43120)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19804.0.0 or later.
