CVE-2023-54074

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net/mlx5e: Use correct encap attribute during invalidation<br /> <br /> With introduction of post action infrastructure most of the users of encap<br /> attribute had been modified in order to obtain the correct attribute by<br /> calling mlx5e_tc_get_encap_attr() helper instead of assuming encap action<br /> is always on default attribute. However, the cited commit didn&amp;#39;t modify<br /> mlx5e_invalidate_encap() which prevents it from destroying correct modify<br /> header action which leads to a warning [0]. Fix the issue by using correct<br /> attribute.<br /> <br /> [0]:<br /> <br /> Feb 21 09:47:35 c-237-177-40-045 kernel: WARNING: CPU: 17 PID: 654 at drivers/net/ethernet/mellanox/mlx5/core/en_tc.c:684 mlx5e_tc_attach_mod_hdr+0x1cc/0x230 [mlx5_core]<br /> Feb 21 09:47:35 c-237-177-40-045 kernel: RIP: 0010:mlx5e_tc_attach_mod_hdr+0x1cc/0x230 [mlx5_core]<br /> Feb 21 09:47:35 c-237-177-40-045 kernel: Call Trace:<br /> Feb 21 09:47:35 c-237-177-40-045 kernel: <br /> Feb 21 09:47:35 c-237-177-40-045 kernel: mlx5e_tc_fib_event_work+0x8e3/0x1f60 [mlx5_core]<br /> Feb 21 09:47:35 c-237-177-40-045 kernel: ? mlx5e_take_all_encap_flows+0xe0/0xe0 [mlx5_core]<br /> Feb 21 09:47:35 c-237-177-40-045 kernel: ? lock_downgrade+0x6d0/0x6d0<br /> Feb 21 09:47:35 c-237-177-40-045 kernel: ? lockdep_hardirqs_on_prepare+0x273/0x3f0<br /> Feb 21 09:47:35 c-237-177-40-045 kernel: ? lockdep_hardirqs_on_prepare+0x273/0x3f0<br /> Feb 21 09:47:35 c-237-177-40-045 kernel: process_one_work+0x7c2/0x1310<br /> Feb 21 09:47:35 c-237-177-40-045 kernel: ? lockdep_hardirqs_on_prepare+0x3f0/0x3f0<br /> Feb 21 09:47:35 c-237-177-40-045 kernel: ? pwq_dec_nr_in_flight+0x230/0x230<br /> Feb 21 09:47:35 c-237-177-40-045 kernel: ? rwlock_bug.part.0+0x90/0x90<br /> Feb 21 09:47:35 c-237-177-40-045 kernel: worker_thread+0x59d/0xec0<br /> Feb 21 09:47:35 c-237-177-40-045 kernel: ? __kthread_parkme+0xd9/0x1d0
