TITLE

Snapdragon Mobile Buffer error vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2018-011480

DESCRIPTION

Improper input validation in WLAN encrypt/decrypt module can lead to a buffer copy in Snapdragon Mobile in version SD 835, SD 845, SD 850. Snapdragon Mobile Contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Qualcomm Closed-Source Components are prone to multiple unspecified vulnerabilities. An attacker can exploit these issues to perform unauthorized actions. This may aid in further attacks. These issues are being tracked by Android Bug IDs A-68326803, A-62213176, A-73539234, A-72950814, A-77484228, A-111090697, A-68326811, A-78240387, A-78239234, A-68326819, A-71501117, A-72950958, A-74236425, A-77484229, A-79419793, A-109677940, A-109677982, A-109677964, A-109678202, A-109678380, A-111091377, A-111090533, A-111093202, A-111090698, A-111093021, and A-111093167. Qualcomm SD 835, SD 845 and SD 850 are all central processing unit (CPU) products of Qualcomm (Qualcomm). WLAN encrypt/decrypt is one of the WLAN encryption/decryption modules. A local attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service
