Vector：CVSS：3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
漏洞简述：
In the Linux kernel, the following vulnerability has been resolved:wifi: ath12k: fix warning when unbindingIf there is an error during some initialization related to firmware,the buffers dp->tx_ring[i].tx_status are released.However this is released again when the device is unbinded (ath12k_pci),and we get:WARNING: CPU: 0 PID: 2098 at mm/slub.c:4689 free_large_kmalloc+0x4d/0x80Call Trace:free_large_kmallocath12k_dp_freeath12k_core_deinitath12k_pci_remove...The issue is always reproducible from a VM because the MSI addressinginitialization is failing.In order to fix the issue, just set the buffers to NULL after releasing inorder to avoid the double free.
