CVE-2013-3229: Linux Kernel

Medium severity, CVSS 4.9. EPSS: 0.4% chance of exploitation in the next 30 days.

The iucv_sock_recvmsg function in net/iucv/af_iucv.c in the Linux kernel before 3.9-rc7 does not initialize a certain length variable, which allows local users to obtain sensitive information from kernel stack memory via a crafted recvmsg or recvfrom system call.

Affected products
