    Field note · TruePositive EditorialCurated

    Samsung Mobile Devices Insertion of Sensitive Information Into Log File Vulnerability — Samsung mobile devices running Android 11, 12, and 13 contain an insertion of sensitive information into log file vulnerability that allows a privileged, local attacker to conduct an address space layout randomization (ASLR) bypass. Listed in the CISA KEV catalog (added 2023-05-19) — confirmed exploited in the wild, not theoretical. FIRST EPSS puts the chance of exploitation in the next 30 days at ~3%. Treat it as real and prioritize remediation over triage.

    Remediation · TruePositive EditorialCurated

    Required action for Samsung Mobile Devices: Apply updates per vendor instructions. CISA set a federal remediation due date of 2023-06-09. After patching, verify the vulnerable path is no longer reachable before closing the finding.
