Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: fix crash when unbinding
If there is an error during some initialization related to firmware,
the function ath12k_dp_cc_cleanup is called to release resources.
However this is released again when the device is unbinded (ath12k_pci),
and we get:
BUG: kernel NULL pointer dereference, address: 0000000000000020
at RIP: 0010:ath12k_dp_cc_cleanup.part.0+0xb6/0x500 [ath12k]
Call Trace:
ath12k_dp_cc_cleanup
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 to NULL the released structure in
ath12k_dp_cc_cleanup at the end.
Affected configurations
• linux linux kernel (>= 6.3 < 6.6.64)
• linux linux kernel (>= 6.7 < 6.11.11)
• linux linux kernel (>= 6.12 < 6.12.2)
