In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: clear initialized flag for deinit-ed srng lists
In a number of cases we see kernel panics on resume due
to ath11k kernel page fault, which happens under the
following circumstances:
1) First ath11k_hal_dump_srng_stats() call
Last interrupt received for each group:
ath11k_pci 0000:01:00.0: group_id 0 22511ms before
ath11k_pci 0000:01:00.0: group_id 1 14440788ms before
[..]
ath11k_pci 0000:01:00.0: failed to receive control response completion, polling..
ath11k_pci 0000:01:00.0: Service connect timeout
ath11k_pci 0000:01:00.0: failed to connect to HTT: -110
ath11k_pci 0000:01:00.0: failed to start core: -110
ath11k_pci 0000:01:00.0: firmware crashed: MHI_CB_EE_RDDM
ath11k_pci 0000:01:00.0: already resetting count 2
ath11k_pci 0000:01:00.0: failed to wait wlan mode request (mode 4): -110
ath11k_pci 0000:01:00.0: qmi failed to send wlan mode off: -110
ath11k_pci 0000:01:00.0: failed to reconfigure driver on crash recovery
[..]
2) At this point reconfiguration fails (we have 2 resets) and
ath11k_core_reconfigure_on_crash() calls ath11k_hal_srng_deinit()
which destroys srng lists. However, it does not reset per-list
->initialized flag.
3) Second ath11k_hal_dump_srng_stats() call sees stale ->initialized
flag and attempts to dump srng stats:
Last interrupt received for each group:
ath11k_pci 0000:01:00.0: group_id 0 66785ms before
