In the Linux kernel, the following vulnerability has been resolved: tracing: Fix use-after-free in print_graph_function_flags during tracer switching Kairui reported a UAF issue in print_graph_function_flags() during ftrace stress testing [1]. This issue can be reproduced if puting a 'mdelay(10)' after 'mutex_unlock(&trace_types_lock)' in s_start(), and executing the following script: $ echo function_graph > current_tracer $ cat trace > /dev/null & $ sleep 5 # Ensure the 'cat' reaches the 'mdelay(10)' point $ echo timerlat > current_tracer The root cause lies in the two calls to print_graph_function_flags within print_trace_line during each s_show(): * One through 'iter->trace->print_line()'; * Another through 'event->funcs->trace()', which is hidden in print_trace_fmt() before print_trace_line returns. Tracer switching only updates the former, while the latter continues to use the print_line function of the old tracer, which in the script above is print_graph_function_flags. Moreover, when switching from the 'function_graph' tracer to the 'timerlat' tracer, s_start only calls graph_trace_close of the 'function_graph' tracer to free 'iter->private', but does not set it to NULL. This provides an opportunity for 'event->funcs->trace()' to use an invalid 'iter->private'. To fix this issue, set 'iter->private' to NULL immediately after freeing it in graph_trace_close(), ensuring that an invalid pointer is not passed to other tracers. Additionally, clean up the unnecessary 'iter->private = NULL' during each 'cat trace' when using wakeup and irqsoff tracers. [1] https://lore.kernel.org/all/20231112150030.84609-1-ryncsn@gmail.com/

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For Debian 11 bullseye, these problems have been fixed in version     5.10.237-1.  This additionally includes many more bug fixes from     stable updates 5.10.235-5.10.237.

    We recommend that you upgrade your linux packages.

An update of the linux package has been released.

The version of kernel installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2025-22035 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: tracing: Fix use-after-free in     print_graph_function_flags during tracer switching Kairui reported a UAF issue in     print_graph_function_flags() during ftrace stress testing [1]. This issue can be reproduced if puting a     'mdelay(10)' after 'mutex_unlock(&trace_types_lock)' in s_start(), and executing the following script: $     echo function_graph > current_tracer $ cat trace > /dev/null & $ sleep 5 # Ensure the 'cat' reaches the     'mdelay(10)' point $ echo timerlat > current_tracer The root cause lies in the two calls to     print_graph_function_flags within print_trace_line during each s_show(): * One through     'iter->trace->print_line()'; * Another through 'event->funcs->trace()', which is hidden in     print_trace_fmt() before print_trace_line returns. Tracer switching only updates the former, while the     latter continues to use the print_line function of the old tracer, which in the script above is     print_graph_function_flags. Moreover, when switching from the 'function_graph' tracer to the 'timerlat'     tracer, s_start only calls graph_trace_close of the 'function_graph' tracer to free 'iter->private', but     does not set it to NULL. This provides an opportunity for 'event->funcs->trace()' to use an invalid     'iter->private'. To fix this issue, set 'iter->private' to NULL immediately after freeing it in     graph_trace_close(), ensuring that an invalid pointer is not passed to other tracers. Additionally, clean     up the unnecessary 'iter->private = NULL' during each 'cat trace' when using wakeup and irqsoff tracers.
