Answer in brief
CVE-2026-72150 records a Unknown severity vulnerability in sunrpc: fix uninitialized xprt_create_args structure. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
