CVE-2023-21053

Name of the Vulnerable Software and Affected Versions Android kernel

Description The issue is related to a possible out of bounds read in the sms ExtractCbLanguage function of sms CellBroadcast.c due to a missing bounds check. This could lead to remote information disclosure with no additional execution privileges needed. User interaction is not required for exploitation.

Recommendations For Android kernel, consider applying a patch that includes a bounds check in the sms ExtractCbLanguage function to prevent out of bounds reads. As a temporary workaround, restrict access to the sms CellBroadcast.c module to minimize the risk of exploitation.
