Description

wifi: ath12k: fix warning when unbinding

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->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/0x80

Call Trace:

free_large_kmalloc

ath12k_dp_free

ath12k_core_deinit

ath12k_pci_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.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.
