Vulnerability Title
bonding: fix NULL deref in bond_rr_gen_slave_id
来源: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
bonding: fix NULL deref in bond_rr_gen_slave_id
Fix a NULL dereference of the struct bonding.rr_tx_counter member because
if a bond is initially created with an initial mode != zero (Round Robin)
the memory required for the counter is never created and when the mode is
changed there is never any attempt to verify the memory is allocated upon
switching modes.
This causes the following Oops on an aarch64 machine:
