high Tenable Cloud Security Plugin ID 470578

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: sunrpc: fix uninitialized
 xprt_create_args structure The xprt_create_args structure is allocated on the stack without initialization
 in rpc_sysfs_xprt_switch_add_xprt_store(). While some fields are manually populated, critical fields like
 srcaddr, bc_xps, and flags contain uninitialized stack garbage. This can lead to: 1. Kernel panic when
 xs_setup_xprt() dereferences garbage srcaddr 2. Information leak if srcaddr points to sensitive stack data
 3. Unpredictable behavior if flags has random bits set The fix is to zero-initialize the structure to
 ensure all unused fields are NULL/0, preventing the transport setup code from acting on garbage data.
 (CVE-2026-72150)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19999.44.21 or later.
