In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Use mlx5ipsecrxstatusdestroy to correctly delete status rules
rxcreate no longer allocates a modifyhdr instance that needs to be cleaned up. The mlx5modifyheader_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.
