Description
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.
