CVE-2026-34831

A flaw was found in Rack. A remote attacker can exploit this vulnerability by requesting a non-existent path containing percent-encoded UTF-8 characters. This causes Rack::Filesfail to incorrectly calculate the Content-Length header, using Stringsize instead of Stringbytesize for multibyte...

CVE-2020-37216

Hirschmann HiOS devices versions prior to 08.1.00 and 07.1.01 contain a denial of service vulnerability in the EtherNet/IP stack where improper handling of packet length fields allows remote attackers to crash or hang the device. Attackers can send specially crafted UDP EtherNet/IP packets with a...

CVE-2026-23462

A flaw was found in the Linux kernel's Bluetooth subsystem HIDP. A local attacker can exploit a use-after-free vulnerability by failing to properly drop a reference to an L2CAP Logical Link Control and Adaptation Protocol connection during a user removal callback. This memory corruption flaw may...

CVE-2026-23439

A flaw was found in the Linux kernel. A privileged local user can exploit a vulnerability in the udptunnel module when IPv6 Internet Protocol version 6 is disabled. This occurs because the udpsockcreate6 function incorrectly returns success without creating a socket, leading to a NULL pointer...

EUVD-2026-18714

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfconntracksip: fix Content-Length u32 truncation in siphelptcp siphelptcp parses the SIP Content-Length header with simplestrtoul, which returns unsigned long, but stores the result in unsigned int clen. On 64-bit...

EUVD-2026-18711

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfconntrackh323: check for zero length in DecodeQ931 In DecodeQ931, the UserUserIE code path reads a 16-bit length from the packet, then decrements it by 1 to skip the protocol discriminator byte before passing it to...

EUVD-2026-18712

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfconntrackh323: fix OOB read in decodeint CONS case In decodeint, the CONS case calls getbitsbs, 2 to read a length value, then calls getuintbs, len without checking that len bytes remain in the buffer. The existing...

EUVD-2026-18696

In the Linux kernel, the following vulnerability has been resolved: net: usb: cdcncm: add ndpoffset to NDP16 nframes bounds check cdcncmrxverifyndp16 validates that the NDP header and its DPE entries fit within the skb. The first check correctly accounts for ndpoffset: if ndpoffset + sizeofstruct...

EUVD-2026-18680

In the Linux kernel, the following vulnerability has been resolved: udptunnel: fix NULL deref caused by udpsockcreate6 when CONFIGIPV6=n When CONFIGIPV6 is disabled, the udpsockcreate6 function returns 0 success without actually creating a socket. Callers such as foucreate then proceed to...

EUVD-2026-18684

In the Linux kernel, the following vulnerability has been resolved: ipv6: add NULL checks for idev in SRv6 paths in6devget can return NULL when the device has no IPv6 configuration e.g. MTU IPV6MINMTU or after NETDEVUNREGISTER. Add NULL checks for idev returned by in6devget in both...

CVE-2026-31393

A flaw was found in the Linux kernel's Bluetooth L2CAP Logical Link Control and Adaptation Protocol component. A remote attacker could send a specially crafted, truncated L2CAP information response L2CAPINFORSP packet. This insufficient validation of the payload length before accessing data leads...

CVE-2026-23448

A flaw was found in the Linux kernel's cdcncm module. An incorrect bounds check in the cdcncmrxverifyndp16 function, responsible for validating Network Data Protocol NDP entries, allows Datagram Pointer Entries DPE to extend beyond the intended buffer. This can lead to an out-of-bounds read when...

CVE-2026-23459

A flaw was found in the Linux kernel's IP tunnel iptunnel functionality. Incorrect handling of tunnel statistics, specifically within the iptunnelxmitstats function, could lead to a mismatch in how data is processed. On 32-bit kernel systems, this issue may result in data corruption or system...

CVE-2026-31396

In the Linux kernel, the following vulnerability has been resolved: net: macb: fix use-after-free access to PTP clock PTP clock is registered on every opening of the interface and destroyed on every closing. However it may be accessed via gettsinfo ethtool call which is possible while the interfa...
