Astra Linux – Vulnerability in c-ares

c-ares is an asynchronous resolver library. c-ares is vulnerable to denial of service attacks. When a target resolver sends a query, the attacker creates a malformed UDP packet with a length of 0 and sends it back to the target resolver. The target resolver misinterprets this 0-length field as an...

CVE-2026-72712 Nmap 7.99 Denial of Service via Zero-Length TCP Option Packet

Nmap versions up to and including 7.99 contains a denial of service vulnerability that allows remote attackers to crash the application by sending a crafted packet containing a zero-length TCP option. The malformed packet forces the Packet:parseoptions function in nselib/packet.lua to allocate...

CVE-2026-10678 NULL-pointer / out-of-bounds write in Zephyr MCTP I2C+GPIO target binding driven by an unauthenticated I2C controller

The MCTP-over-I2C+GPIO target binding in Zephyr subsys/pmci/mctp/mctpi2cgpiotarget.c processes pseudo-register writes from an I2C bus master byte-by-byte in mctpi2cgpiotargetwritereceived without validating the order or the receive buffer. In the affected versions the MCTPI2CGPIORXMSGADDR data...

CVE-2026-53994

ProFTPD modsftp contains a heap-based buffer overflow reachable by an authenticated SFTP user. The fxppacketread function accepts the attacker-supplied 32-bit big-endian SFTP packet length without a minimum sanity check. A value of 0 causes an unsigned subtraction elsewhere in the read path to...
