TITLE

Snapdragon Mobile and Snapdragon Wear Integer overflow vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2018-011612

DESCRIPTION

Possible integer overflow may happen in WLAN during memory allocation in Snapdragon Mobile, Snapdragon Wear in version IPQ8074, MDM9206, MDM9607, MDM9650, SD 425, SD 427, SD 430, SD 435, SD 450, SD 625, SD 650/52, SD 835, SD 845, SD 850, SDA660, SDM630, SDM632, SDM636, SDM660, SDM710, Snapdragon_High_Med_2016. Snapdragon Mobile and Snapdragon Wear Contains an integer overflow 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-120487384, A-117119000, A-117118976, A-117118295, A-117119172, A-122473270, A-109678120, A-111093019, A-111092813, A-111089816, A-111092945, A-111092919, A-111091938, A-111093762, A-111093242, A-111090373, A-111092814, A-111093763, A-111093243, A-111089817, A-111092400, A-111090534, A-111091378, A-111092946, A-111093022, A-111093244, A-111092888, A-111093280, A-111092401, A-111093259, A-111090535, A-112279580, A-112279127, A-119049704, A-119052960, A-114042276, A-117118499, A-117119174, A-117119152, A-117118789, A-122472377, A-120483842, A-122472139 and A-122473145. Qualcomm IPQ8074, etc. are all central processing unit (CPU) products of Qualcomm (Qualcomm) applied to different platforms. An integer overflow vulnerability exists in WLAN in several Qualcomm Snapdragon products. Currently there is no information about this vulnerability, please keep an eye on CNNVD or vendor announcements
