- Summary
- CVE-2026-46069 affecting package kernel for versions less than 6.6.141.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
wifi: mwifiex: fix use-after-free in mwifiex_adapter_cleanup()
The mwifiex_adapter_cleanup() function uses timer_delete() (non-synchronous) for the wakeup_timer before the adapter structure is freed. This is incorrect because timer_delete() does not wait for any running timer callback to complete.
If the wakeup_timer callback (wakeup_timer_fn) is executing when mwifiex_adapter_cleanup() is called, the callback will continue to access adapter fields (adapter->hw_status, adapter->if_ops.card_reset, etc.) which may be freed by mwifiex_free_adapter() called later in the mwifiex_remove_card() path.
Use timer_delete_sync() instead to ensure any running timer callback has completed before returning.
