[SRU][F/J][PATCH 0/2] CVE-2024-56599

[Abdur Rahman]

This patch fixes use-after-free error in the Atheros 10k wireless driver. Due 
to CONFIG_INIT_ON_FREE_DEFAULT_ON, pointers of struct cfg80211_registered_device 
*rdev are set to NULL in the ath10k_core_destroy() function. Then 
destroy_workqueue() uses the pointer and kernel panic happens.
