AF_PACKET packet_set_ring Privilege Escalation

This module exploits a heap-out-of-bounds write in the packetsetring function in net/packet/afpacket.c AFPACKET in the Linux kernel to execute code as root CVE-2017-7308. The bug was initially introduced in 2011 and patched in version 4.10.6, potentially affecting a large number of kernels; howev...

kernel: compat IPT_SO_SET_REPLACE setsockopt

A flaw was discovered in processing setsockopt for 32 bit processes on 64 bit systems. This flaw will allow attackers to alter arbitrary kernel memory when unloading a kernel module. This action is usually restricted to root-privileged users but can also be leveraged if the kernel is compiled wit...

AF_PACKET chocobo_root Privilege Escalation

This module exploits a race condition and use-after-free in the packetsetring function in net/packet/afpacket.c AFPACKET in the Linux kernel to execute code as root CVE-2016-8655. The bug was initially introduced in 2011 and patched in 2016 in version 4.4.0-53.74, potentially affecting a large...

Linux kernel 'mark_source_chains()' denial of service vulnerability

The Linux kernel is the kernel used by the operating system Linux, released by the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that originates from a boundary error in the 'marksourcechains' function in the net/ipv4/netfilter/iptables.c file. When...

DEBIAN-CVE-2015-8709

kernel/ptrace.c in the Linux kernel through 4.4.1 mishandles uid and gid mappings, which allows local users to gain privileges by establishing a user namespace, waiting for a root process to enter that namespace with an unsafe uid or gid, and then using the ptrace system call. NOTE: the vendor...
