  "details": "In the Linux kernel, the following vulnerability has been resolved:  bonding: do not clear curr_active_slave prematurely when releasing all slaves  When releasing all slaves during bond destruction (all == true), __bond_release_one() unconditionally clears bond-\u003ecurr_active_slave to NULL in every iteration.  If a backup slave is released before the active slave, bond_alb_deinit_slave() triggers rlb_teach_disabled_mac_on_primary(), which increments the active slave dev promiscuity counter and sets bond_info-\u003eprimary_is_promisc = 1.  Because bond-\u003ecurr_active_slave was prematurely cleared to NULL when releasing the backup slave, the subsequent iteration releasing the active slave evaluates oldcurrent as NULL, so bond_change_active_slave(bond, NULL) is skipped. Consequently, bond_alb_handle_active_change() is never called to decrement the promiscuity counter, permanently leaking promiscuous mode on the physical device after bond teardown.  When oldcurrent == slave, bond_change_active_slave(bond, NULL) already sets bond-\u003ecurr_active_slave to NULL. We only need to avoid selecting a new active slave when all == true. Replace the if (all) branch with if (!all \u0026\u0026 oldcurrent == slave).",
