Kernel Tree For Xiaomi 11 Lite NE 5G
In the function lim_process_sme_update_access_policy_vendor_ie, update_vendor_ie is parsed from the incomming msg. num_bytes is the length of the IE and is retrived as update_vendor_ie->ie[1]+2. This num_bytes value is used as the size to copy the IE to pe_session_entry->access_policy_vendor_ie The update_vendor_ie->ie[1] can have a maximum value of SIR_MAC_MAX_IE_LENGTH . As the num_bytes is of uint8_t,a possible integer overflow can occur in lim_process_sme_update_access_policy_vendor_ie when num_bytes is assigned with update_vendor_ie->ie[1]. Change the data type of the num_bytes to uint16_t so that it can hold the value of update_vendor_ie->ie[1] without truncation.
