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

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...

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...

CVE-2026-72249

A flaw was found in the Linux kernel's netfilter flowtable. When processing the IP-in-IP IPIP header, the system incorrectly uses routing information from the opposite direction to calculate packet headroom and fragmentation flags. This can lead to incorrect packet handling and potentially affect...

CVE-2026-72246

A flaw was found in the Linux kernel's netfilter flowtable component. This vulnerability arises from an error in how the system sets up tunnel routes, specifically in handling network packet encapsulation and tunnel information. An attacker could potentially exploit this to cause incorrect networ...

GO-2026-6237 Denial of service via malformed IPv4 packet in github.com/insomniacslk/dhcp

In github.com/insomniacslk/dhcp/dhcpv4/nclient4, BroadcastRawUDPConn.ReadFrom does not validate that the IPv4 payload length is sufficient to hold a UDP header before calculating the DHCP payload length. A frame with an IPv4 total-length field specifying fewer than eight payload bytes results in ...

UBUNTU-CVE-2026-75032

A flaw was found in BlueZ. Insufficient validation of packet length fields in GetFolderItems responses within the Audio/Video Remote Control Profile AVRCP implementation allows a malicious Bluetooth device within range to cause an out-of-bounds memory read. This vulnerability, affecting the...
