kernel: net/packet: overflow in check for priv area size

It was found that the packetsetring function of the Linux kernel's networking implementation did not properly validate certain block-size data. A local attacker with CAPNETRAW capability could use this flaw to trigger a buffer overflow resulting in a system crash or a privilege escalation...

The vulnerability of the packet_set_ring function in the kernel of Linux operating systems allows a attacker to increase their privileges, cause service failures, or execute arbitrary code.

The vulnerability of the packetsetring function in the Linux operating system’s kernel is related to deficiencies in access control. Exploiting this vulnerability allows a malicious actor, who has local privileges as CAPNETRAW, to create PFPACKET sockets, initiate racing states and memory usage...

Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: The issue is related to a heap out-of-bounds condition in AF PACKET sockets, similar to a previously disclosed problem. It involves a race condition between a socket option that change...

The vulnerability of the `packet_set_ring` function in the Linux operating system allows a hacker to trigger a service failure or cause other adverse effects.

The vulnerability of the packetsetring function in the Linux operating system arises from the execution of an operation beyond the buffer boundaries in memory. Exploiting this vulnerability can allow a local attacker to cause service failures or other adverse effects through a specially crafted...
