Patch now

HIGH 8.4EXPLOITEDMITIGATE

CVE-2013-2597 is a high-severity flaw (CVSS 8.4) affecting android-msm, reported as exploited in the wild. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Stack-based buffer overflow in the acdb_ioctl function in audio_acdb.c in the acdb audio driver for the Linux kernel 2.6.x and 3.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, allows attackers to gain privileges via an application that leverages /dev/msm_acdb access and provides a large size value in an ioctl argument.
