Description The issue is related to a possibility of integer overflow in keymaster 4 while allocating memory due to multiplication of large numcerts value and size of keymaster bob which can lead to memory corruption. This affects various Qualcomm Snapdragon products, including Auto, Compute, Connectivity, Consumer IOT, Industrial IOT, Mobile, Voice & Music, Wearables, and Wired Infrastructure and Networking.

Recommendations For each of the affected Qualcomm Snapdragon versions, consider applying configuration changes to restrict the multiplication of large numcerts values and the size of keymaster bob to prevent memory corruption. As a temporary workaround, consider disabling the vulnerable keymaster 4 functionality until a patch is available. Restrict access to the vulnerable module to minimize the risk of exploitation. Avoid using the numcerts value in the affected keymaster 4 functionality until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
