"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nbonding: do not clear curr_active_slave prematurely when releasing all slaves\n\nWhen releasing all slaves during bond destruction (all == true),\n__bond_release_one() unconditionally clears bond->curr_active_slave to\nNULL in every iteration.\n\nIf a backup slave is released before the active slave,\nbond_alb_deinit_slave() triggers rlb_teach_disabled_mac_on_primary(),\nwhich increments the active slave dev promiscuity counter and sets\nbond_info->primary_is_promisc = 1.\n\nBecause bond->curr_active_slave was prematurely cleared to NULL when\nreleasing the backup slave, the subsequent iteration releasing the active\nslave evaluates oldcurrent as NULL, so bond_change_active_slave(bond, NULL)\nis skipped. Consequently, bond_alb_handle_active_change() is never called\nto decrement the promiscuity counter, permanently leaking promiscuous\nmode on the physical device after bond teardown.\n\nWhen oldcurrent == slave, bond_change_active_slave(bond, NULL) already sets\nbond->curr_active_slave to NULL. We only need to avoid selecting a new\nactive slave when all == true. Replace the if (all) branch with\nif (!all && oldcurrent == slave)."
