Description

In the Linux kernel, the following vulnerability has been resolved: tracing: fprobe events: Fix possible UAF on modules Commit ac91052f0ae5 ("tracing: tprobe-events: Fix leakage of module refcount") moved try_module_get() from __find_tracepoint_module_cb() to find_tracepoint() caller, but that introduced a possible UAF because the module can be unloaded before try_module_get(). In this case, the module object should be freed too. Thus, try_module_get() does not only fail but may access to the freed object. To avoid that, try_module_get() in __find_tracepoint_module_cb() again.

Affected configurations

• linux linux kernel (>= 6.12.21 < 6.12.24) • linux linux kernel (>= 6.13.9 < 6.13.12) • linux linux kernel (>= 6.14.1 < 6.14.3) • linux linux kernel 6.14 • linux linux kernel 6.15
