In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Use mlx5_ipsec_rx_status_destroy to correctly delete status rules
rx_create no longer allocates a modify_hdr instance that needs to be cleaned up. The mlx5_modify_header_dealloc call will lead to a NULL pointer dereference. A leak in the rules also previously occurred since there are now two rules populated related to status.
