"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nath11k: mhi: use mhi_sync_power_up()\n\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.\n\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\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\n\nTested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03003-QCAHSPSWPL_V1_V2_SILICONZ_LITE-2"
