CVE-2026-98095
A flaw was found in the Linux kernel's afpacket network subsystem. When parsing packet headers, user-supplied length values are improperly converted from an unsigned integer to a signed integer. A local user can exploit this vulnerability by submitting an excessively large packet length, causing ...
CVE-2026-90059
A flaw was found in the Linux kernel's stmmac network driver. The driver's receive RX path, after being converted to zero-copy, failed to correctly align IP packet headers. This misalignment, particularly on ARM32 architectures, can cause the system to panic when processing certain network packet...
CVE-2026-53014
A flaw was found in the Linux kernel. When the kernel's traffic control TC subsystem processes network packets for redirection across different types of network devices, it can incorrectly handle packet headers. This can lead to corruption of network packet data. A local attacker could potentiall...
CVE-2026-53091
The CVE-2026-53091 issue concerns the Linux kernel’s handling of GSO packet headers during qdisc_pkt_len_segs_init(). The root cause is that many ndo_start_xmit() paths assume headers are already in skb->head, while tso_build_hdr() may copy from skb->data, and qdisc_pkt_len_segs_init() diss...
Cisco IOS XR security vulnerabilities
Cisco IOS XR is an operating system developed by the American company Cisco for its network devices. There is a security vulnerability in Cisco IOS XR, which stems from insufficient input validation of IS-IS packet headers. This vulnerability may lead to unexpected restarts of the IS-IS process a...
tcpdump 4.99.6
tcpdump allows you to dump the traffic on a network. It can be used to print out the headers and/or contents of packets on a network interface that matches a given expression. You can use this tool to track down network problems, to detect many attacks, or to monitor the network activities...
