CVE-2010-5321 is a medium-severity vulnerability rated 4.3/10 on the CVSS scale. Memory leak in drivers/media/video/videobuf-core.c in the videobuf subsystem in the Linux kernel 2.6.x through 4.x allows local users to cause a denial of service (memory consumption) by leveraging /dev/video access for a series of mmap calls that require new allocations, a different vulnerability than CVE-2007-6761. NOTE: as of 2016-06-18, this affects only 11 drivers that have not been updated to use videobuf2 instead of videobuf.. EPSS estimates a 0.40% chance of exploitation in the next 30 days.
