CVE-2026-98827

A flaw was found in the Linux kernel's ath9khtc wireless network driver. An attacker transmitting large network packets can trigger a Denial of Service DoS or system crash through memory corruption. This issue occurs because the driver limits aggregated transmit packets only by count rather than...

DEBIAN-CVE-2026-115863

ConnMan through 2.0 has a stack-based buffer overflow via a DHCPv6 Reply message. This occurs in getdomains in gdhcp/client.c. It copies a fixed NSMAXDNAME 1025 bytes from a DHCPv6 DOMAINLIST option 24 value into a 1026-byte stack buffer dnsname regardless of the actual option length, then walks...

CVE-2026-115863

Versions of ConnMan through 2.0 are vulnerable to a stack-based buffer overflow in the get_domains function located in gdhcp/client.c. The flaw occurs because the software copies a fixed 1025 bytes from a DHCPv6 DOMAIN_LIST (option 24) into a 1026-byte stack buffer regardless of the actual option...

CVE-2026-97631

A flaw was found in EDK2. Due to improper buffer size calculations in the firmware, an unauthenticated remote attacker can trigger a buffer overflow. Successful exploitation can lead to arbitrary code execution or cause a denial of service DoS...

CVE-2026-53921

odhcpd is the DHCPv6, DHCPv4, and router-advertisement server used by OpenWrt. Prior to version 25.12, odhcpd's DHCPv6 IA response handler writes past the end of a fixed 512-byte stack buffer pdbuf when a single DHCPv6 REQUEST carries enough IA options to nearly exhaust the reply space. Two...

CVE-2016-2233

CVE-2016-2233 CVE-2016-2233 is a stack-based buffer overflow vulnerability related with a wide-used IRC software Hexchat. We build a IRC server and launch the attack on it to make all the client connected to the server crash. We exploited our attack on Ubuntu 12.04 using Python. We make a patch t...

CVE-2026-53921

A critical stack-based buffer overflow exists in the odhcpd daemon of OpenWrt , affecting versions prior to 24.10.8 and 25.12.5 . The vulnerability is triggered during the serialization of DHCPv6 Reply packets in the build_ia() and dhcpv6_ia_handle_IAs() functions. When processing a specially cra...
