Last modified Jun 17, 2026

CVE-2017-7308 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. The packet_set_ring function in net/packet/af_packet.c in the Linux kernel through 4.10.6 does not properly validate certain block-size data, which allows local users to cause a denial of service (integer signedness error and out-of-bounds write), or gain privileges (if the CAP_NET_RAW capability is held), via crafted system calls.. EPSS estimates a 17.83% chance of exploitation in the next 30 days.
