Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: perf/ftrace: Fix WARNING in
 __unregister_ftrace_function perf_ftrace_function_unregister() unconditionally calls
 unregister_ftrace_function() without checking whether the ftrace_ops was ever successfully registered.
 This triggers a WARN_ON in __unregister_ftrace_function() when the ops doesn't have FTRACE_OPS_FL_ENABLED
 set. This can happen during perf_event_alloc() error cleanup when perf_trace_destroy() is called via
 __free_event() on an event whose ftrace_ops registration failed or was already torn down by
 perf_try_init_event()'s err_destroy path. The call path is: perf_event_alloc() error cleanup ->
 __free_event() -> event->destroy() [tp_perf_event_destroy] -> perf_trace_destroy() ->
 perf_trace_event_close() -> TRACE_REG_PERF_CLOSE -> perf_ftrace_function_unregister() ->
 unregister_ftrace_function() -> __unregister_ftrace_function() -> WARN_ON(!(ops->flags &
 FTRACE_OPS_FL_ENABLED)) Fix this by checking FTRACE_OPS_FL_ENABLED before attempting to unregister. If the
 ops is not enabled, just free the filter and return success. (CVE-2026-97443)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.739.5 or later.
