So, ad_clear_agg can be executed even, when\nnum_of_ports!=0. Than bond_3ad_unbind_slave can be executed again for,\npreviously cleared aggregator. NOTE: at this time bond_3ad_unbind_slave\nwill not update slave ports list, because lag_ports==NULL. So, here we\ngot slave ports, pointing to freed aggregator memory.\n\nFix with checking actual number of ports in group (as was before\ncommit 0622cab0341c (\"bonding: fix 802.3ad aggregator reselection\") ),\nbefore ad_clear_agg().\n\nThe KASAN logs are as follows:\n\n[ 767.617392] ==================================================================\n[ 767.630776] BUG: KASAN: use-after-free in bond_3ad_state_machine_handler+0x13dc/0x1470\n[ 767.638764] Read of size 2 at addr ffff00011ba9d430 by task kworker/u8:7/767\n[ 767.647361] CPU: 3 PID: 767 Comm: kworker/u8:7 Tainted: G O 5.15.11 #15\n[ 767.655329] Hardware name: DNI AmazonGo1 A7040 board (DT)\n[ 767.660760] Workqueue: lacp_1 bond_3ad_state_machine_handler\n[ 767.666468] Call trace:\n[ 767.668930] dump_backtrace+0x0/0x2d0\n[ 767.672625] show_stack+0x24/0x30\n[ 767.675965] dump_stack_lvl+0x68/0x84\n[ 767.679659] print_address_description.constprop.0+0x74/0x2b8\n[ 767.685451] kasan_report+0x1f0/0x260\n[ 767.689148] __asan_load2+0x94/0xd0\n[ 767.692667] bond_3ad_state_machine_handler+0x13dc/0x1470", "affected": [ { "vendor": "Linux", "product": "Linux", "defaultStatus": "unaffected", "versions": [ { "version": "0622cab0341cac6b30da177b0faa39fae0680e71", "status": "affected", "versionType": "git", "lessThan": "a853b7a3a9fd1d74a4ccdd9cd73512b7dace2f1e" }, { "version": "0622cab0341cac6b30da177b0faa39fae0680e71", "status": "affected", "versionType": "git", "lessThan": "b90ac60303063a43e17dd4aec159067599d255e6" }, { "version": "0622cab0341cac6b30da177b0faa39fae0680e71", "status": "affected", "versionType": "git", "lessThan": "f162f7c348fa2a5555bafdb5cc890b89b221e69c" }, { "version": "0622cab0341cac6b30da177b0faa39fae0680e71", "status": "affected", "versionType": "git", "lessThan": "893825289ba840afd86bfffcb6f7f363c73efff8" }, { "version": "0622cab0341cac6b30da177b0faa39fae0680e71", "status": "affected", "versionType": "git", "lessThan": "63b2fe509f69b90168a75e04e14573dccf7984e6" }, { "version": "0622cab0341cac6b30da177b0faa39fae0680e71", "status": "affected", "versionType": "git", "lessThan": "ef0af7d08d26c5333ff4944a559279464edf6f15" }, { "version": "0622cab0341cac6b30da177b0faa39fae0680e71", "status": "affected", "versionType": "git", "lessThan": "2765749def4765c5052a4c66445cf4c96fcccdbc" }, { "version": "0622cab0341cac6b30da177b0faa39fae0680e71", "status": "affected", "versionType": "git", "lessThan": "050133e1aa2cb49bb17be847d48a4431598ef562" } ] }, { "vendor": "Linux", "product": "Linux", "defaultStatus": "affected", "versions": [ { "version": "4.7", "status": "affected" }, { "version": "0", "status": "unaffected", "versionType": "semver", "lessThan": "4.7" }, { "version": "4.9.322", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "4.9.*" }, { "version": "4.14.287", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "4.14.*" }, { "version": "4.19.251", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "4.19.*" }, { "version": "5.4.204", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.4.*" }, { "version": "5.10.129", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.10.*" }, { "version": "5.15.53", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.15.*" }, { "version": "5.18.10", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.18.*" }, { "version": "5.19", "status": "unaffected", "versionType": "original_commit_for_fix", "lessThanOrEqual": "*" } ] } ] } } }
