Vulnerability Title
wifi: ath12k: fix uaf in ath12k_core_init()
Source: NVD (National Vulnerability Database)
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix uaf in ath12k_core_init() When the execution of ath12k_core_hw_group_assign() or ath12k_core_hw_group_create() fails, the registered notifier chain is not unregistered properly. Its memory is freed after rmmod, which may trigger to a use-after-free (UAF) issue if there is a subsequent access to this notifier chain. Fixes the issue by calling ath12k_core_panic_notifier_unregister() in failure cases. Call trace: notifier_chain_register+0x4c/0x1f0 (P) atomic_notifier_chain_register+0x38/0x68 ath12k_core_init+0x50/0x4e8 [ath12k] ath12k_pci_probe+0x5f8/0xc28 [ath12k] pci_device_probe+0xbc/0x1a8 really_probe+0xc8/0x3a0 __driver_probe_device+0x84/0x1b0 driver_probe_device+0x44/0x130 __driver_attach+0xcc/0x208 bus_for_each_dev+0x84/0x100 driver_attach+0x2c/0x40 bus_add_driver+0x130/0x260 driver_register+0x70/0x138 __pci_register_driver+0x68/0x80 ath12k_pci_init+0x30/0x68 [ath12k] ath12k_init+0x28/0x78 [ath12k] Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
