Summary

In the Linux kernel, the following vulnerability has been resolved:

media: venus: hfi_parser: add check to avoid out of bound access

There is a possibility that init_codecs is invoked multiple times during manipulated payload from video firmware. In such case, if codecs_count can get incremented to value more than MAX_CODEC_NUM, there can be OOB access. Reset the count so that it always starts from beginning.
