  "description": "In the Linux kernel, the following vulnerability has been resolved:  SUNRPC: Fix the svc_deferred_event trace class  Fix a NULL deref crash that occurs when an svc_rqst is deferred while the sunrpc tracing subsystem is enabled. svc_revisit() sets dr-\u003Exprt to NULL, so it can\u0027t be relied upon in the tracepoint to provide the remote\u0027s address.  Unfortunately we can\u0027t revert the \u0022svc_deferred_class\u0022 hunk in commit ece200ddd54b (\u0022sunrpc: Save remote presentation address in svc_xprt for trace events\u0022) because there is now a specific check of event format specifiers for unsafe dereferences. The warning that check emits is:    event svc_defer_recv has unsafe dereference of argument 1  A \u0022%pISpc\u0022 format specifier with a \u0022struct sockaddr *\u0022 is indeed flagged by this check.  Instead, take the brute-force approach used by the svcrdma_qp_error tracepoint. Convert the dr::addr field into a presentation address in the TP_fast_assign() arm of the trace event, and store that as a string. This fix can be backported to -stable kernels.  In the meantime, commit c6ced22997ad (\u0022tracing: Update print fmt check to handle new __get_sockaddr() macro\u0022) is now in v5.18, so this wonky fix can be replaced with __sockaddr() and friends properly during the v5.19 merge window.",
