kernel: Heap out-of-bounds read in AF_PACKET sockets

A race condition issue was found in the way the raw packet socket implementation in the Linux kernel networking subsystem handled synchronization. A local user able to open a raw packet socket requires the CAPNETRAW capability could use this to waste resources in the kernel's ring buffer or...

Linux kernel packet_set_ring function local 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 'packetsetring' function of the net/packet/afpacket.c file in Linux kernel versions 4.10.6 and earlier, which stems from a program that...

DEBIAN-CVE-2017-7308

The packetsetring function in net/packet/afpacket.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 CAPNETRAW capability is held...

UBUNTU-CVE-2017-7308

The packetsetring function in net/packet/afpacket.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 CAPNETRAW capability is held...

DEBIAN-CVE-2017-6346

Race condition in net/packet/afpacket.c in the Linux kernel before 4.9.13 allows local users to cause a denial of service use-after-free or possibly have unspecified other impact via a multithreaded application that makes PACKETFANOUT setsockopt system calls...

The vulnerability in the net/packet/af_packet.c component of the Linux operating system allows a hacker to trigger a service failure or increase their privileges.

The vulnerability in the net/packet/afpacket.c component of the Linux operating system exists due to insufficient checking of resource states when resources are allowed to be shared among multiple processes. Exploiting this vulnerability can allow an attacker to increase their privileges or cause...

USN-3151-3 linux-snapdragon vulnerability

Philip Pettersson discovered a race condition in the afpacket implementation in the Linux kernel. A local unprivileged attacker could use this to cause a denial of service system crash or run arbitrary code with administrative privileges...
