Description

In the Linux kernel, the following vulnerability has been resolved: bonding: fix use-after-free due to enslave fail after slave array update Fix a use-after-free which happens due to enslave failure after the new slave has been added to the array. Since the new slave can be used for Tx immediately, we can use it after it has been freed by the enslave error cleanup path which frees the allocated slave memory. Slave update array is supposed to be called last when further enslave failures are not
