[FFmpeg-devel] [PATCH 4/4] avcodec/siren: Increase noise category 5 and 6

[Michael Niedermayer]

The entry read is not used in subsequent computation, thus its
value is not important.

Fixes: out of array read
Fixes: 28578/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_SIREN_fuzzer-6332019122503680
