--- title: "CVE-2013-3076\n | Ubuntu" description: Ubuntu is an open source software operating system that runs from the desktop, to the cloud, to all your internet connected things. url: https://ubuntu.com/security/CVE-2013-3076?format=md keywords: index, follow --- # CVE-2013-3076 Publication date 22 April 2013 Last updated 4 July 2026 --- Ubuntu priority **Low** [Why this priority?](https://ubuntu.com/security/cves/about#priority ) Toggle side navigation ## Description The crypto API in the Linux kernel through 3.9-rc8 does not initialize certain length variables, which allows local users to obtain sensitive information from kernel stack memory via a crafted recvmsg or recvfrom system call, related to the hash\_recvmsg function in crypto/algif\_hash.c and the skcipher\_recvmsg function in crypto/algif\_skcipher.c. ### From the Ubuntu Security Team An information leak was discovered in the Linux kernel's crypto API. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. ## Status Show unmaintained releases | Package | Ubuntu Release | Status | | --- | ---
