      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/mlx5: E-Switch: fix use-after-free in mlx5_eswitch_termtbl_put\n\nIn mlx5_eswitch_termtbl_put(), the zero-ref cleanup check reads\ntt->ref_count after termtbl_mutex has been released.  Two concurrent\ncallers on the same mlx5_termtbl_handle race: one decrements ref_count\nto zero, removes the hash entry, and calls kfree(tt) while the other\nhas already dropped the mutex and is about to evaluate\nif (!tt->ref_count), producing a use-after-free.\n\nFix this by capturing the result of the decrement into a stack-local\nlast variable before dropping the mutex.  The cleanup decision is now\nmade entirely under termtbl_mutex, and tt is not touched after\nkfree.",
