The sctp_sf_do_5_2_4_dupcook function in net/sctp/sm_statefuns.c in the SCTP implementation in the Linux kernel before 3.8.5 does not properly handle associations during the processing of a duplicate COOKIE ECHO chunk, which allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via crafted SCTP traffic.
CVE-2013-0310 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2025-04-11 N/A
The cipso_v4_validate function in net/ipv4/cipso_ipv4.c in the Linux kernel before 3.4.8 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via an IPOPT_CIPSO IP_OPTIONS setsockopt system call.
CVE-2011-2942 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2025-04-11 N/A
A certain Red Hat patch to the __br_deliver function in net/bridge/br_forward.c in the Linux kernel 2.6.18 on Red Hat Enterprise Linux (RHEL) 5 allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by leveraging connectivity to a network interface that uses an Ethernet bridge device.

CVE-2023-28625 2 Openidc, Redhat 2 Mod Auth Openidc, Enterprise Linux 2025-04-10 7.5 High
mod_auth_openidc is an authentication and authorization module for the Apache 2.x HTTP server that implements the OpenID Connect Relying Party functionality. In versions 2.0.0 through 2.4.13.1, when `OIDCStripCookies` is set and a crafted cookie supplied, a NULL pointer dereference would occur, resulting in a segmentation fault. This could be used in a Denial-of-Service attack and thus presents an availability risk. Version 2.4.13.2 contains a patch for this issue. As a workaround, avoid using `OIDCStripCookies`.
