AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N

Name of the Vulnerable Software and Affected Versions Android kernel

Description The issue is related to a possible out of bounds read in the SAEMM RetrievEPLMNList function of SAEMM ContextManagement.c due to a missing bounds check. This could lead to remote information disclosure post-authentication 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 for the SAEMM RetrievEPLMNList function to prevent out of bounds read. As a temporary workaround, restrict access to the SAEMM ContextManagement.c module to minimize the risk of exploitation.
