kernel: packet: use consistent hard_header_len in non-ring send paths

An out-of-bounds write problem was observed in packetsendmsgspkt in net/packet/afpacket.c in the Linux Kernel. In this flaw, AFPACKET hardheaderlen race may allow local privilege escalation...

CVE-2026-74747

A flaw was found in the Linux kernel's IP Virtual Server IPVS component. A local attacker can manipulate the IP Header Length ihl field within network packets. This manipulation can lead to an out-of-bounds access when the kernel attempts to revalidate embedded headers, potentially causing system...

CVE-2026-65979

OpenEXR (the reference implementation for the EXR image format, widely used in the motion picture industry) versions 3.4.0 through 3.4.12 contain an out-of-bounds read in the HTJ2K decoder . The decoder parses a header-length field (PLEN ) from a chunk's compressed data and advances the codestrea...

CVE-2026-65979 OpenEXR: Out-of-bounds read in HTJ2K decoder from unvalidated chunk header length (PLEN)

OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. From version 3.4.0 through 3.4.12, the HTJ2K decoder parses a header-length field PLEN from a chunk's compressed data but never checks that this value fits within the...

CVE-2026-74724

A flaw was found in the Linux kernel's IPVS IP Virtual Server component. A local attacker can exploit this vulnerability by manipulating packets processed by IPVS, specifically within the ipvsnaticmp function. This manipulation can lead to an out-of-bounds write due to improper handling of the IP...

CVE-2026-74701

A flaw was found in the Open vSwitch component of the Linux kernel. When a specially crafted packet with ETHPTEB protocol arrives on an ARPHRDNONE device, the keyextract function does not properly verify the Ethernet header length. This oversight allows a remote attacker to trigger a kernel bug,...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: mac80211: The issue in ieee80211scanrx involves checking the skb length. This code requires hard-coded compile-time constants for determining the header length check. Instead, a dynamic determination based on the frame type shoul...

CVE-2026-74701 net/openvswitch: check Ethernet header length in key_extract()

In the Linux kernel, the following vulnerability has been resolved: net/openvswitch: check Ethernet header length in keyextract When a packet arrives on an ARPHRDNONE device e.g. TUN, ovsflowkeyextract trusts the user-provided skb-protocol field: if it is ETHPTEB, the packet is classified as...

EUVD-2026-59126

In the Linux kernel, the following vulnerability has been resolved: batman-adv: mcast: avoid OOB read of numdests header Before the access to struct batadvtvlvmcasttracker's numdests, it is attempted to check whether enough space is actually in the network header. But instead of using offsetofend...

CVE-2026-72319: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: ipvs: ensure inner headers in ICMP errors are in headroom Sashiko points out that after stripping the outer headers with pskbpull we should ensure the inner IP headers in ICMP errors from tunnels are present in the skb headroom f...

CVE-2026-68299

Summary: CVE-2026-68299 affects the Linux kernel vmxnet3 driver. When handling Geneve-encapsulated packets, vmxnet3_get_hdr_len() may misinterpret header fields because gdesc->rcd.v4/v6/tcp describe the outer header, while the inner header can differ. The completion descriptor’s VMXNET3_RCD_HD...
