CVE-2026-63383

In libevent prior to 2.1.13 and 2.2.2-alpha, decode_tag_internal() in event_tagging.c requests at most five bytes via evbuffer_pullup but iterates over the full logical buffer length. A fragmented evbuffer holding a six-byte malformed tag can advance past the pullup window, causing an out-of-boun...

BSA-2019-828

Security Advisory ID : BSA-2019-828 Component : TCP SACK Revision : 2.0 An excessive resource consumption flaw was found in the way the Linux kernel's networking subsystem processed TCP Selective Acknowledgment SACK segments. While processing SACK segments, the Linux kernel's socket buffer SKB da...

Kernel: tcp: excessive resource consumption while processing SACK blocks allows remote denial of service

An excessive resource consumption flaw was found in the way the Linux kernel's networking subsystem processed TCP Selective Acknowledgment SACK segments. While processing SACK segments, the Linux kernel's socket buffer SKB data structure becomes fragmented, which leads to increased resource...
