  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\nath11k: mhi: use mhi_sync_power_up()\nIf amss.bin was missing ath11k would crash during 'rmmod ath11k_pci'. The\nreason for that was that we were using mhi_async_power_up() which does not\ncheck any errors. But mhi_sync_power_up() on the other hand does check for\nerrors so let's use that to fix the crash.\nI was not able to find a reason why an async version was used.\nath11k_mhi_start() (which enables state ATH11K_MHI_POWER_ON) is called from\nath11k_hif_power_up(), which can sleep. So sync version should be safe to use\nhere.\n[  145.569731] general protection fault, probably for non-canonical address 0xdffffc0000000000: 0000 [#1] PREEMPT SMP DEBUG_PAGEALLOC KASAN PTI\n[  145.569789] KASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007]\n[  145.569843] CPU: 2 PID: 1628 Comm: rmmod Kdump: loaded Tainted: G        W         5.16.0-wt-ath+ #567\n[  145.569898] Hardware name: Intel(R) Client Systems NUC8i7HVK/NUC8i7HVB, BIOS HNKBLi70.86A.0067.2021.0528.1339 05/28/2021\n[  145.569956] RIP: 0010:ath11k_hal_srng_access_begin+0xb5/0x2b0 [ath11k]\n[  145.570028] Code: df 48 89 fa 48 c1 ea 03 80 3c 02 00 0f 85 ec 01 00 00 48 8b ab a8 00 00 00 48 b8 00 00 00 00 00 fc ff df 48 89 ea 48 c1 ea 03 <0f> b6 14 02 48 89 e8 83 e0 07 83 c0 03 45 85 ed 75 48 38 d0 7c 08\n[  145.570089] RSP: 0018:ffffc900025d7ac0 EFLAGS: 00010246\n[  145.570144] RAX: dffffc0000000000 RBX: ffff88814fca2dd8 RCX: 1ffffffff50cb455\n[  145.570196] RDX: 0000000000000000 RSI: ffff88814fca2dd8 RDI: ffff88814fca2e80\n[  145.570252] RBP: 0000000000000000 R08: 0000000000000000 R09: ffffffffa8659497\n[  145.570329] R10: fffffbfff50cb292 R11: 0000000000000001 R12: ffff88814fca0000\n[  145.570410] R13: 0000000000000000 R14: ffff88814fca2798 R15: ffff88814fca2dd8\n[  145.570465] FS:  00007fa399988540(0000) GS:ffff888233e00000(0000) knlGS:0000000000000000\n[  145.570519] CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n[  145.570571] CR2: 00007fa399b51421 CR3: 0000000137898002 CR4: 00000000003706e0\n[  145.570623] Call Trace:\n[  145.570675]  <TASK>\n[  145.570727]  ? ath11k_ce_tx_process_cb+0x34b/0x860 [ath11k]\n[  145.570797]  ath11k_ce_tx_process_cb+0x356/0x860 [ath11k]\n[  145.570864]  ? tasklet_init+0x150/0x150\n[  145.570919]  ? ath11k_ce_alloc_pipes+0x280/0x280 [ath11k]\n[  145.570986]  ? tasklet_clear_sched+0x42/0xe0\n[  145.571042]  ? tasklet_kill+0xe9/0x1b0\n[  145.571095]  ? tasklet_clear_sched+0xe0/0xe0\n[  145.571148]  ? irq_has_action+0x120/0x120\n[  145.571202]  ath11k_ce_cleanup_pipes+0x45a/0x580 [ath11k]\n[  145.571270]  ? ath11k_pci_stop+0x10e/0x170 [ath11k_pci]\n[  145.571345]  ath11k_core_stop+0x8a/0xc0 [ath11k]\n[  145.571434]  ath11k_core_deinit+0x9e/0x150 [ath11k]\n[  145.571499]  ath11k_pci_remove+0xd2/0x260 [ath11k_pci]\n[  145.571553]  pci_device_remove+0x9a/0x1c0\n[  145.571605]  __device_release_driver+0x332/0x660\n[  145.571659]  driver_detach+0x1e7/0x2c0\n[  145.571712]  bus_remove_driver+0xe2/0x2d0\n[  145.571772]  pci_unregister_driver+0x21/0x250\n[  145.571826]  __do_sys_delete_module+0x30a/0x4b0\n[  145.571879]  ? free_module+0xac0/0xac0\n[  145.571933]  ? lockdep_hardirqs_on_prepare.part.0+0x18c/0x370\n[  145.571986]  ? syscall_enter_from_user_mode+0x1d/0x50\n[  145.572039]  ? lockdep_hardirqs_on+0x79/0x100\n[  145.572097]  do_syscall_64+0x3b/0x90\n[  145.572153]  entry_SYSCALL_64_after_hwframe+0x44/0xae\nTested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03003-QCAHSPSWPL_V1_V2_SILICONZ_LITE-2" ],
