In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: fix memory leak in ath12kpciremove()
Kmemleak reported this error:
unreferenced object 0xffff1c165cec3060 (size 32): comm "insmod", pid 560, jiffies 4296964570 (age 235.596s) backtrace: [<000000005434db68>] _kmemcacheallocnode+0x1f4/0x2c0 [<000000001203b155>] kmalloctrace+0x40/0x88 [<0000000028adc9c8>] _requestfirmware+0xb8/0x608 [<00000000cad1aef7>] firmwarerequestnowarn+0x50/0x80 [<000000005011a682>] localpciprobe+0x48/0xd0 [<00000000077cd295>] pcideviceprobe+0xb4/0x200 [<0000000087184c94>] really_probe+0x150/0x2c0
The firmware memory was allocated in ath12kpciprobe(), but not freed in ath12kpciremove() in case ATH12KFLAGQMIFAIL bit is set. So call ath12kfw_unmap() to free the memory.
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.2.0-02280-QCAHMTSWPLV1.0V2.0_SILICONZ-1
