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.

The remote Ubuntu 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8962-1 advisory.

    Duoming Zhou discovered race conditions in the AX.25 amateur radio protocol implementation in the Linux     kernel, leading to use-after-free vulnerabilities. A local attacker could possibly use this to cause a     denial of service (system crash). (CVE-2022-1205)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

An update of the linux package has been released.

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)

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

  - 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)

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