Use after free vulnerability in set_nft_pid and signal_handler function of NFC driver prior to SMR Oct-2022 Release 1 allows attackers to perform malicious actions.

Weakness

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
