Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 6.1.11 Description: The issue is related to the implementation of the NET/ROM network protocol in the Linux kernel. It involves a use-after-free error in the af netrom.c module, specifically in the nr release...

kernel: netfilter: use-after-free in the packet processing context

A use-after-free flaw was found in the packet processing context in net/netfilter/xtables.c in netfilter in the Linux Kernel. This issue occurs when the per-CPU sequence count is mishandled during concurrent iptables rules replacement and can be exploited with the CAPNETADMIN capability in an...

kernel: xdp_umem_reg in net/xdp/xdp_umem.c has an out-of-bounds write which could result in crash and data coruption

An out-of-bounds OOB memory access flaw was found in the Network XDP the eXpress Data Path module in the Linux kernel's xdpumemreg function in net/xdp/xdpumem.c. When a user with special user privilege of CAPNETADMIN or root calls setsockopt to register umem ring on XDP socket, passing the headro...

An issue was discovered in the Linux kernel before 5.6.7. xdp_umem_reg in net/xdp/xdp_umem.c has an out-of-bounds write (by a user with the CAP_NET_ADMIN capability) because of a lack of headroom validation.

Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 5.6.7 Description: An issue in the Linux kernel allows for an out-of-bounds write due to a lack of headroom validation in xdp umem reg in net/xdp/xdp umem.c. This can be exploited by a user with the CAP NET ADMI...

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...

kernel: Missing capabilities check in net/netfilter/nfnetlink_cthelper.c allows for unprivileged access to systemwide nfnl_cthelper_list structure

The net/netfilter/nfnetlinkcthelper.c function in the Linux kernel through 4.14.4 does not require the CAPNETADMIN capability for new, get, and del operations. This allows local users to bypass intended access restrictions because the nfnlcthelperlist data structure is shared across all net...
