high Tenable Cloud Security Plugin ID 471294

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/umem: Fix truncation for block
 sizes >= 4G When the iommu is used the linearization of the mapping can give a single block that is very
 large split across multiple SG entries. When __rdma_block_iter_next() reassembles the split SG entries it
 is overflowing the 32 bit stack values and computed the wrong DMA addresses for blocks after the
 truncation. Use the right types to hold DMA addresses. (CVE-2026-53133)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19907.0.0 or later.
