Linux Distros Unpatched Vulnerability : CVE-2022-49065

medium Nessus Plugin ID 225624

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - 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->xprt to NULL, so it can't be relied upon in the tracepoint to provide the remote's address. Unfortunately we can't revert the svc_deferred_class hunk in commit ece200ddd54b (sunrpc: Save remote presentation address in svc_xprt for trace events) 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 %pISpc format specifier with a struct sockaddr * 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 (tracing: Update print fmt check to handle new
 __get_sockaddr() macro) is now in v5.18, so this wonky fix can be replaced with __sockaddr() and friends properly during the v5.19 merge window. (CVE-2022-49065)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
