kernel: inactive elements in nft_pipapo_walk
A use-after-free flaw was found in the Netfilter subsystem in the Linux kernel via the nftpipapowalk function. This issue may allow a local user with CAPNETADMIN capability to trigger an application crash, information disclosure, or local privilege escalation...
kernel: nf_tables: stack-out-of-bounds-read in nft_byteorder_eval()
An out-of-bounds OOB memory access flaw was found in the Netfilter module in the Linux kernel's nftbyteordereval in net/netfilter/nftbyteorder.c. A bound check failure allows a local attacker with CAPNETADMIN access to cause a local privilege escalation issue due to incorrect data alignment...

kernel: netfilter: use-after-free in nf_tables when processing batch requests can lead to privilege escalation
A use-after-free vulnerability was found in the Netfilter subsystem of the Linux kernel when processing batch requests to update nftables configuration. This vulnerability can be abused to perform arbitrary reads and writes in kernel memory. A local user with CAPNETADMIN capability could use this...
DEBIAN-CVE-2023-1076
A flaw was found in the Linux Kernel. The tun/tap sockets have their socket UID hardcoded to 0 due to a type confusion in their initialization function. While it will be often correct, as tuntap devices require CAPNETADMIN, it may not always be the case, e.g., a non-root user only having that...
SUSE CVE-2013-1827
net/dccp/ccid.h in the Linux kernel before 3.5.4 allows local users to gain privileges or cause a denial of service NULL pointer dereference and system crash by leveraging the CAPNETADMIN capability for a certain 1 sender or 2 receiver getsockopt call...
SUSE CVE-2017-17448
net/netfilter/nfnetlinkcthelper.c in the Linux kernel through 4.14.4 does not require the CAPNETADMIN capability for new, get, and del operations, which allows local users to bypass intended access restrictions because the nfnlcthelperlist data structure is shared across all net namespaces...
UBUNTU-CVE-2020-12659
An issue was discovered in the Linux kernel before 5.6.7. xdpumemreg in net/xdp/xdpumem.c has an out-of-bounds write by a user with the CAPNETADMIN capability because of a lack of headroom validation...
kernel: Missing namespace check in net/netlink/af_netlink.c allows for network monitors to observe systemwide activity
The netlinkdelivertapskb function in net/netlink/afnetlink.c in the Linux kernel, through 4.14.4, does not restrict observations of Netlink messages to a single net namespace, when CONFIGNLMON is enabled. This allows local users to obtain sensitive information by leveraging the CAPNETADMIN...
UBUNTU-CVE-2018-1065
The netfilter subsystem in the Linux kernel through 4.15.7 mishandles the case of a rule blob that contains a jump but lacks a user-defined chain, which allows local users to cause a denial of service NULL pointer dereference by leveraging the CAPNETRAW or CAPNETADMIN capability, related to...

Name of the Vulnerable Software and Affected Versions: Linux kernel versions through 4.15.7 Description: The netfilter subsystem in the Linux kernel mishandles the case of a rule blob that contains a jump but lacks a user-defined chain, which allows local users to cause a denial of service NULL...
The vulnerability of the sock_setsockopt function in the kernel of the Linux operating system’s net/core/sock.c file allows a hacker to cause a service failure or exert other effects.
The vulnerability of the socksetsockopt function in the kernel’s net/core/sock.c file in the Linux operating system arises from the execution of an operation beyond the buffer boundaries in memory. Exploiting this vulnerability allows a local attacker to cause a service failure or other adverse...
UBUNTU-CVE-2012-6704
The socksetsockopt function in net/core/sock.c in the Linux kernel before 3.5 mishandles negative values of sksndbuf and skrcvbuf, which allows local users to cause a denial of service memory corruption and system crash or possibly have unspecified other impact by leveraging the CAPNETADMIN...

Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 4.8.14 Description: The issue is related to the mishandling of negative values of sk sndbuf and sk rcvbuf by the sock setsockopt function in the Linux kernel. This can be exploited by local users with the CAP NE...
UBUNTU-CVE-2016-7917
The nfnetlinkrcvbatch function in net/netfilter/nfnetlink.c in the Linux kernel before 4.5 does not check whether a batch message's length field is large enough, which allows local users to obtain sensitive information from kernel memory or cause a denial of service infinite loop or out-of-bounds...
DEBIAN-CVE-2013-2548
The cryptoreportone function in crypto/cryptouser.c in the report API in the crypto user configuration API in the Linux kernel through 3.8.2 uses an incorrect length value during a copy operation, which allows local users to obtain sensitive information from kernel memory by leveraging the...
