In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: fix warning when unbinding
If there is an error during some initialization related to firmware, the buffers dp->txring[i].txstatus are released. However this is released again when the device is unbinded (ath12kpci), and we get: WARNING: CPU: 0 PID: 2098 at mm/slub.c:4689 freelargekmalloc+0x4d/0x80 Call Trace: freelargekmalloc ath12kdpfree ath12kcoredeinit ath12kpci_remove ...
The issue is always reproducible from a VM because the MSI addressing initialization is failing.
In order to fix the issue, just set the buffers to NULL after releasing in order to avoid the double free.
