Denial Of Service (DoS)

kernel-rt is vulnerable to denial of service DoS attacks. The vulnerability exists as the XFRM dump policy implementation in net/xfrm/xfrmuser.c in the Linux kernel before 4.13.11 allows local users to gain privileges or cause a denial of service use-after-free via a crafted SORCVBUF setsockopt...

Denial Of Service (DoS)

Linux kernel is vulnerable to denial of service. A user-after-free UAF occurs in sysmqnotify due to the sock pointer not being set to NULL upon entry into the retry logic, allowing an attacker to cause a denial of service condition during a user-space close of a Netlink socket...

Denial Of Service (DoS)

kernel is vulnerable to denial of service DoS attacks. The vulnerability exists as the brcmfcfg80211mgmttx function in drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c in the Linux kernel before 4.12.3 allows local users to cause a denial of service buffer overflow and system crash or...

Authorization Bypass

kernel-rt is vulnerable to authorization bypass attacks. The vulnerability exists as the Netlink implementation in the Linux kernel through 3.14.1 does not provide a mechanism for authorizing socket operations based on the opener of a socket, which allows local users to bypass intended access...

kernel: NULL pointer dereference in af_netlink.c:__netlink_ns_capable() allows for denial of service

The Linux kernel was found to be vulnerable to a NULL pointer dereference bug in the netlinknscapable function in the net/netlink/afnetlink.c file. A local attacker could exploit this when a net namespace with a netnsid is assigned to cause a kernel panic and a denial of service...

kernel: Use-after-free in sys_mq_notify()

A use-after-free flaw was found in the Netlink functionality of the Linux kernel networking subsystem. Due to the insufficient cleanup in the mqnotify function, a local attacker could potentially use this flaw to escalate their privileges on the system...

kernel: NULL pointer dereference in af_netlink.c:__netlink_ns_capable() allows for denial of service

The Linux kernel was found to be vulnerable to a NULL pointer dereference bug in the netlinknscapable function in the net/netlink/afnetlink.c file. A local attacker could exploit this when a net namespace with a netnsid is assigned to cause a kernel panic and a denial of service...

Linux kernel denial of service vulnerability (CNVD-2018-24298)

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. A denial of service vulnerability exists in the 'netlinknscapable' function of the net/netlink/afnetlink.c file in versions of Linux kernel prior to 4.15-rc8, which ca...

CVE-2018-14646

The Linux kernel before 4.15-rc8 was found to be vulnerable to a NULL pointer dereference bug in the netlinknscapable function in the net/netlink/afnetlink.c file. A local attacker could exploit this when a net namespace with a netnsid is assigned to cause a kernel panic and a denial of service...

UBUNTU-CVE-2018-14646

Linux kernel denial of service vulnerability (CNVD-2018-20469)

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. A security vulnerability exists in Linux kernel version 4.14.67, which stems from a program that incorrectly handles interactions between XFRM Netlink messages,...

DEBIAN-CVE-2018-17977

The Linux kernel 4.14.67 mishandles certain interaction among XFRM Netlink messages, IPPROTOAH packets, and IPPROTOIP packets, which allows local users to cause a denial of service memory consumption and system hang by leveraging root access to execute crafted applications, as demonstrated on...

CVE-2018-17977

CVE-2018-17977 affects Linux kernel 4.14.67, where interaction between XFRM Netlink messages, IPPROTO_AH, and IPPROTO_IP can be exploited locally (with root) to trigger memory exhaustion and system hang; demonstrated on CentOS 7. The provided documents do not specify a fix or patch version.
