CVE-2026-48175 · Severity: info · Published 2026-11-05

Samsung semiconductor components fail to properly validate RRC (Radio Resource Control) messages, which can lead to an out-of-bounds memory read. An attacker with network access to a device using the affected component could trigger this vulnerability to cause a denial-of-service condition, rendering the device temporarily unavailable.

## Technical details

The vulnerability exists in RRC message processing within Samsung semiconductor components, where malformed input fails proper bounds checking, resulting in an out-of-bounds read. Attack requires network-level access to send crafted RRC messages. Successful exploitation leads to denial-of-service via crash or resource exhaustion, though the advisory reports no known active exploitation.
