Name of the Vulnerable Software and Affected Versions Android versions Android-11 through Android-13

Description The issue is related to a possible out of bounds write due to a missing bounds check in the A2DP BuildCodecHeaderSbc function of a2dp sbc.cc. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.

Recommendations For Android versions Android-11 through Android-13, update to a version that includes the fix for the issue in A2DP BuildCodecHeaderSbc of a2dp sbc.cc. As a temporary workaround, consider restricting access to the A2DP BuildCodecHeaderSbc function until a patch is available.
