Last modified Jun 16, 2026

CVE-2013-3076 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.35% chance of exploitation in the next 30 days.
