CVE-2013-3076 is a local information disclosure vulnerability affecting the Linux kernel up to version 3.9-rc8. It stems from uninitialized length variables in the crypto API, specifically within the hash_recvmsg and skcipher_recvmsg functions. This allows local attackers to extract sensitive data from kernel stack memory via crafted recvmsg or recvfrom system calls. With a CVSS score of 4.9 (AV:L/AC:L/Au:N/C:C/I:N/A:N), it poses a moderate risk, primarily due to its high confidentiality impact. There is no evidence of active exploitation, publicly available exploit code, or significant community discussion surrounding this CVE.
