CVE-2026-74559

A flaw was found in the Linux kernel's AFXDP eXpress Data Path networking component. This vulnerability, located in the xskbuildskb function, involves improper handling of network packet descriptors. When processing large or malformed multi-buffer packets, the system fails to properly drain...

CVE-2026-72408

A flaw was found in the Linux kernel's geneve component. An attacker can send a specially crafted Geneve Generic Network Virtualization Encapsulation packet that exploits a discrepancy in how GRO Generic Receive Offload hints are processed. The genevegrocomplete function processes these hints...

CVE-2026-72407

A flaw was found in the Geneve module of the Linux kernel. This vulnerability arises from an incorrect validation of the inner network offset within the genevegrocomplete function. A discrepancy between how genevegrocomplete and genevegroreceive process packet information can lead to an...

CVE-2026-75147

FFmpeg before commit 983dae9 contains an out-of-bounds read in the AV1 RTP packetizer libavformat/rtpencav1.c. The keyframe detection loop that searches for a sequence header OBU advanced its pointer and remaining-size counter by the encoded header length plus the OBU payload size without first...

CVE-2026-72350

A flaw was found in the Linux kernel's netfilter component, specifically in xtu32. A local attacker with privileges to configure netfilter rules could craft a malicious u32 rule with an invalid shift count. This could lead to an undefined shift out-of-bounds during packet evaluation, potentially...

CVE-2026-72712

A flaw was found in Nmap. A remote attacker can exploit this denial of service vulnerability by sending a specially crafted packet that includes a zero-length Transmission Control Protocol TCP option. This malformed packet forces the application to enter an infinite loop during packet processing,...

CVE-2026-75147 FFmpeg Out-of-Bounds Read in AV1 RTP Packetizer via rtpenc_av1.c

FFmpeg before commit 983dae9 contains an out-of-bounds read in the AV1 RTP packetizer libavformat/rtpencav1.c. The keyframe detection loop that searches for a sequence header OBU advanced its pointer and remaining-size counter by the encoded header length plus the OBU payload size without first...

CVE-2026-58085

After dispatching a decrypt operation to OCF and receiving the result, the wg4 driver failed to check whether the MAC verification step succeeded. The driver thus silently accepted packets with an invalid Poly1305 authentication tag. A remote attacker who can send UDP packets to a WireGuard...

CVE-2026-58085 Missing MAC validation in wg(4) packet decryption

After dispatching a decrypt operation to OCF and receiving the result, the wg4 driver failed to check whether the MAC verification step succeeded. The driver thus silently accepted packets with an invalid Poly1305 authentication tag. A remote attacker who can send UDP packets to a WireGuard...

CVE-2026-58085

CVE-2026-58085 is a missing MAC validation flaw in the wg(4) kernel driver (if_wg) of FreeBSD , which implements the WireGuard VPN protocol. After dispatching a ChaCha20-Poly1305 decrypt operation to the OpenCrypto framework (OCF) , the driver failed to verify whether the Poly1305 MAC step succee...

EUVD-2026-62339

After dispatching a decrypt operation to OCF and receiving the result, the wg4 driver failed to check whether the MAC verification step succeeded. The driver thus silently accepted packets with an invalid Poly1305 authentication tag. A remote attacker who can send UDP packets to a WireGuard...

CVE-2026-72326

A flaw was found in the Linux kernel's CAKE Common Applications Kept Enhanced packet scheduler. This vulnerability arises from the incorrect handling of signed overhead values, which can lead to an integer underflow during packet length calculations. A negative effective length can then wrap to a...

PT-2026-78858

Name of the Vulnerable Software and Affected Versions Wireshark versions 4.6.0 through 4.6.7 Wireshark versions 4.4.0 through 4.4.18 Description A NULL pointer dereference in the Bluetooth BR/EDR FHS protocol dissector can lead to a crash, resulting in a denial of service. Recommendations Update...

PT-2026-78841

Name of the Vulnerable Software and Affected Versions Wireshark versions 4.6.0 through 4.6.7 Wireshark versions 4.4.0 through 4.4.18 Description A crash in the RRC protocol dissector can lead to a denial of service. A dissector is a software component that breaks down network traffic into a...

CVE-2026-72320

A flaw was found in the Linux kernel's netfilter component, specifically within the nftlookup functionality. This issue arises from incorrect handling of 'catchall' elements during 'inverted lookups' in the nftlookupeval function. Due to a logic error where the lookup result is not recomputed,...

CVE-2026-72319

A flaw was found in the Linux kernel's IP Virtual Server IPVS component. This vulnerability occurs when the system processes Internet Control Message Protocol ICMP errors originating from network tunnels. Specifically, after stripping outer packet headers, the IPVS component fails to ensure that...

USN-8645-1: Linux kernel (Oracle) vulnerabilities

Siebe Devroe, Héloïse Gollier, and Mathy Vanhoef discovered that the WiFi implementation in the Linux kernel did not properly handle aggregated frames in mesh networks, due to an incorrect fix for CVE-2020-24588. A physically proximate attacker could use this issue to inject packets. CVE-2025-275...
