How to fix?

There is no fixed version for RHEL:10 kernel-debug-devel-matched.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-debug-devel-matched package and not the kernel-debug-devel-matched package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

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.
