CVE-2013-4739

CVE-2013-4739 is a sensitive information disclosure vulnerability affecting the MSM camera driver in Linux kernel 3.x, specifically within Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other related products. An attacker can exploit this by crafting specific ioctl calls (MSM_MCR_IOCTL_EVT_GET or MSM_JPEG_IOCTL_EVT_GET) to obtain sensitive data directly from kernel stack memory. With a CVSS score of 4.9, this vulnerability has a low attack complexity and requires local access, but it can lead to a complete compromise of confidentiality. There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
