v1 -> v2: - Address the comment to reduce size of queue pointer from queue size - Consider the data size during memcpy to avoid OOB write - Use hweight_long() to count the setbits representing the supported codecs v1: https://lore.kernel.org/all/1690432469-14803-1-git-send-email-quic_vgarodia@xxxxxxxxxxx/ This series primarily adds check at relevant places in venus driver where there are possible OOB accesses due to unexpected payload from venus firmware. The patches describes the specific OOB possibility. Please review and share your feedback.
