Description In the LteRrcNrProAsnDecode function of LteRrcNr Codec.c, there is a possible out of bounds read due to a missing bounds check. This could lead to remote denial of service with no additional execution privileges needed. User interaction is not needed for exploitation.

Recommendations For Android kernel, consider applying a patch that includes a bounds check in the LteRrcNrProAsnDecode function to prevent out of bounds reads. As a temporary workaround, restrict access to the LteRrcNrProAsnDecode function until a patch is available.
