Summary
In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Lag, fix failure to cancel delayed bond work Commit 0d4e8ed139d8 ("net/mlx5: Lag, avoid lockdep warnings") accidentally removed a call to cancel delayed bond work thus it may cause queued delay to expire and fall on an already destroyed work queue. Fix by restoring the call cancel_delayed_work_sync() before destroying the workqueue. This prevents call trace such as this: [ 329.230417] BUG: kernel NULL pointer dereference, address: 0000000000000000 [ 329.231444] #PF: supervisor write access in kernel mode [ 329.232233] #PF: error_code(0x0002) - not-present page [ 329.233007] PGD 0 P4D 0 [ 329.233476] Oops: 0002 [#1] SMP [ 329.234012] CPU: 5 PID: 145 Comm: kworker/u20:4 Tainted: G OE 6.0.0-rc5_mlnx #1 [ 329.235282] Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.13.0-0-gf21b5a4aeb02-prebuilt.qemu.org 04/01/2014 [ 329.236868] Workqueue: mlx5_cmd_0000:08:00.1 cmd_work_handler [mlx5_core] [ 329.237886] RIP: 0010:_raw_spin_lock+0xc/0x20 [ 329.238585] Code: f0 0f b1 17 75 02 f3 c3 89 c6 e9 6f 3c 5f ff 66 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 40 00 0f 1f 44 00 00 31 c0 ba 01 00 00 00 <f0> 0f b1 17 75 02 f3 c3 89 c6 e9 45 3c 5f ff 0f 1f 44 00 00 0f 1f [ 329.241156] RSP: 0018:ffffc900001b0e98 EFLAGS: 00010046 [ 329.241940] RAX: 0000000000000000 RBX: ffffffff82374ae0 RCX: 0000000000000000 [ 329.242954] RDX: 0000000000000001 RSI: 0000000000000014 RDI: 0000000000000000 [ 329.243974] RBP: ffff888106ccf000 R08: ffff8881004000c8 R09: ffff888100400000 [ 329.244990] R10: 0000000000000000 R11: ffffffff826669f8 R12: 0000000000002000 [ 329.246009] R13: 0000000000000005 R14: ffff888100aa7ce0 R15: ffff88852ca80000 [ 329.247030] FS: 0000000000000000(0000) GS:ffff88852ca80000(0000) knlGS:0000000000000000 [ 329.248260] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 329.249111] CR2: 0000000000000000 CR3: 000000016d675001 CR4: 0000000000770ee0 [ 329.250133] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 329.251152] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 [ 329.252176] PKRU: 55555554
