USN-5039-1 linux, linux-aws, linux-kvm, linux-lts-xenial vulnerability

Andy Nguyen discovered that the netfilter subsystem in the Linux kernel contained an out-of-bounds write in its setsockopt implementation. A local attacker could use this to cause a denial of service system crash or possibly execute arbitrary code...

kernel: out-of-bounds write in xt_compat_target_from_user() in net/netfilter/x_tables.c

A flaw was discovered in processing setsockopt IPTSOSETREPLACE or IP6TSOSETREPLACE for 32 bit processes on 64 bit systems. This flaw will allow local user to gain privileges or cause a DoS through user name space. This action is usually restricted to root-privileged users but can also be leverage...

FreeBSD : FreeBSD -- double free in accept_filter(9) socket configuration interface (f8e1e2a6-9791-11eb-b87a-901b0ef719ab)

An unprivileged process can configure an accept filter on a listening socket. This is done using the setsockopt2 system call. The process supplies the name of the accept filter which is to be attached to the socket, as well as a string containing filter-specific information. If the filter...

Problem Description: An unprivileged process can configure an accept filter on a listening socket. This is done using the setsockopt2 system call. The process supplies the name of the accept filter which is to be attached to the socket, as well as a string containing filter-specific information. ...

Information Disclosure

kernel is vulnerable to information disclosure, A local user with CAPNETADMIN can attach an ebpf filter to setsockopt syscall. This filter can be triggered under the right conditions to leak kernel internal information and allows an attacker to determine the layout of information in kernel memory...

Linux Kernel setsockopt System Call Untrusted Pointer Dereference Information Disclosure Vulnerability

This vulnerability allows local attackers to disclose sensitive information on affected installations of Linux Kernel. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling...

FreeBSD ip6_setpktopt Use-After-Free Privilege Escalation Exploit

This Metasploit module exploits a race and use-after-free vulnerability in the FreeBSD kernel IPv6 socket handling. A missing synchronization lock in the IPV62292PKTOPTIONS option handling in setsockopt permits racing ip6setpktopt access to a freed ip6pktopts struct. This exploit overwrites the...

Denial Of Service (DoS)

kernel is vulnerable to denial of service. A divide-by-zero flaw was found in the tcpselectinitialwindow function in the Linux kernel's TCP/IP protocol suite implementation. A local, unprivileged user could use this flaw to trigger a denial of service by calling setsockopt with certain options...

CVE-2016-9793

A flaw was found in the Linux kernel's implementation of setsockopt for the SOSND|RCVBUFFORCE setsockopt system call. Users with non-namespace CAPNETADMIN are able to trigger this call and create a situation in which the sockets sendbuff data size could be negative. This could adversely affect...

F5 Networks BIG-IP : Linux kernel vulnerability (K28241423)

In the Linux kernel through 4.19, a use-after-free can occur due to a race condition between fanoutadd from setsockopt and bind on an AFPACKET socket. This issue exists because of the 15fe076edea787807a7cdc168df832544b58eba6 incomplete fix for a race condition. The code mishandles a certain...

The vulnerability of the irda_setsockopt function in the Linux operating system’s kernel allows a hacker to cause a service failure.

The vulnerability of the irdasetsockopt function net/irda/afirda.c or drivers/staging/irda/net/afirda.c in the Linux kernel is related to the use of memory after it is freed. Exploiting this vulnerability could allow an attacker to cause a service failure...
