Title
Input: gpio-keys - cancel delayed work only in case of GPIO
Summary
In the Linux kernel, the following vulnerability has been resolved: Input: gpio-keys - cancel delayed work only in case of GPIO gpio_keys module can either accept gpios or interrupts. The module initializes delayed work in case of gpios only and is only used if debounce timer is not used, so make sure cancel_delayed_work_sync() is called only when its gpio-backed and debounce_use_hrtimer is false. This fixes the issue seen below when the gpio_keys module is unloaded and an interrupt pin is used instead of GPIO: [ 360.297569] ------------[ cut here ]------------ [ 360.302303] WARNING: CPU: 0 PID: 237 at kernel/workqueue.c:3066 __flush_work+0x414/0x470 [ 360.310531] Modules linked in: gpio_keys(-) [ 360.314797] CPU: 0 PID: 237 Comm: rmmod Not tainted 5.18.0-rc5-arm64-renesas-00116-g73636105874d-dirty #166 [ 360.324662] Hardware name: Renesas SMARC EVK based on r9a07g054l2 (DT) [ 360.331270] pstate: 60400005 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) [ 360.338318] pc : __flush_work+0x414/0x470 [ 360.342385] lr : __cancel_work_timer+0x140/0x1b0 [ 360.347065] sp : ffff80000a7fba00 [ 360.350423] x29: ffff80000a7fba00 x28: ffff000012b9c5c0 x27: 0000000000000000 [ 360.357664] x26: ffff80000a7fbb80 x25: ffff80000954d0a8 x24: 0000000000000001 [ 360.364904] x23: ffff800009757000 x22: 0000000000000000 x21: ffff80000919b000 [ 360.372143] x20: ffff00000f5974e0 x19: ffff00000f5974e0 x18: ffff8000097fcf48 [ 360.379382] x17: 0000000000000000 x16: 0000000000000000 x15: 0000000000053f40 [ 360.386622] x14: ffff800009850e88 x13: 0000000000000002 x12: 000000000000a60c [ 360.393861] x11: 000000000000a610 x10: 0000000000000000 x9 : 0000000000000008 [ 360.401100] x8 : 0101010101010101 x7 : 00000000a473c394 x6 : 0080808080808080 [ 360.408339] x5 : 0000000000000001 x4 : 0000000000000000 x3 : ffff80000919b458 [ 360.415578] x2 : ffff8000097577f0 x1 : 0000000000000001 x0 : 0000000000000000 [ 360.422818] Call trace: [ 360.425299] __flush_work+0x414/0x470 [ 360.429012] __cancel_work_timer+0x140/0x1b0 [ 360.433340] cancel_delayed_work_sync+0x10/0x18 [ 360.437931] gpio_keys_quiesce_key+0x28/0x58 [gpio_keys] [ 360.443327] devm_action_release+0x10/0x18 [ 360.447481] release_nodes+0x8c/0x1a0 [ 360.451194] devres_release_all+0x90/0x100 [ 360.455346] device_unbind_cleanup+0x14/0x60 [ 360.459677] device_release_driver_internal+0xe8/0x168 [ 360.464883] driver_detach+0x4c/0x90 [ 360.468509] bus_remove_driver+0x54/0xb0 [ 360.472485] driver_unregister+0x2c/0x58 [ 360.476462] platform_driver_unregister+0x10/0x18 [ 360.481230] gpio_keys_exit+0x14/0x828 [gpio_keys] [ 360.486088] __arm64_sys_delete_module+0x1e0/0x270 [ 360.490945] invoke_syscall+0x40/0xf8 [ 360.494661] el0_svc_common.constprop.3+0xf0/0x110 [ 360.499515] do_el0_svc+0x20/0x78 [ 360.502877] el0_svc+0x48/0xf8 [ 360.505977] el0t_64_sync_handler+0x88/0xb0 [ 360.510216] el0t_64_sync+0x148/0x14c [ 360.513930] irq event stamp: 4306 [ 360.517288] hardirqs last enabled at (4305): [<ffff8000080b0300>] __cancel_work_timer+0x130/0x1b0 [ 360.526359] hardirqs last disabled at (4306): [<ffff800008d194fc>] el1_dbg+0x24/0x88 [ 360.534204] softirqs last enabled at (4278): [<ffff8000080104a0>] _stext+0x4a0/0x5e0 [ 360.542133] softirqs last disabled at (4267): [<ffff8000080932ac>] irq_exit_rcu+0x18c/0x1b0 [ 360.550591] ---[ end trace 0000000000000000 ]---
