CVE-2026-63495

Libevent (event notification library) versions 2.2.0-alpha-dev through 2.2.2-alpha contain an unbounded memory accumulation vulnerability in its WebSocket server (ws.c). The evws->incomplete_frames buffer accumulates fragmented frames without enforcing a total message-size limit. An unauthenti...

CVE-2026-63495 Libevent: Unbounded memory accumulation in WebSocket server via fragmented frames

Libevent is an event notification library. From 2.2.0-alpha-dev until 2.2.2-alpha, the libevent WebSocket server in ws.c accumulates fragmented frames in evws-incompleteframes without enforcing a total message-size limit. An unauthenticated remote client can repeatedly send fragmented WebSocket...

CVE-2026-55192

A flaw was found in FreeRDP. A malicious Remote Desktop Protocol RDP server can provide a specially crafted H.264 video stream that causes the client's H.264 decoder to read beyond its allocated memory. This out-of-bounds read can lead to the disclosure of sensitive client memory or cause the...

OESA-2026-3407 open-iscsi security update

The Open-iSCSI project is a high-performance, transport independent, multi-platform implementation of RFC3720 iSCSI. Security Fixes: An Improper Limitation of a Pathname to a Restricted Directory 'Path Traversal' vulnerability in open-iscsi allows remote MITM attackers to create root-owned files...

kernel: netfilter: synproxy: refresh tcphdr after skb_ensure_writable

A flaw was found in the Linux kernel's netfilter synproxy module. When handling TCP timestamp options, a stale pointer can be used after memory reallocation. This can result in memory corruption, where data is written to a freed memory area, or lead to packets being sent with an incorrect checksu...

kernel: scsi: target: iscsi: Fix CRC overread and double-free in iscsit_handle_text_cmd()

A flaw was found in the Linux kernel's iSCSI Internet Small Computer System Interface target subsystem. This vulnerability involves a buffer overread and a double-free error when processing iSCSI Text commands. A remote attacker could exploit these issues by sending specially crafted network...

FFmpeg RIST Protocol Heap Buffer Overflow

FFmpeg versions 4.4 through 9.0 contain a heap buffer overflow vulnerability in the RIST protocol reader when built with librist support. A remote unauthenticated attacker can send oversized RIST payloads to an affected async:rist:// receiver, causing attacker-controlled data to be written beyond...

bind: BIND: Denial of Service via specially crafted DNS messages

A flaw was found in the bind component, specifically within the named daemon. This vulnerability allows a remote attacker to send specially crafted Domain Name System DNS messages. These messages, which use unusual classes or meta-classes, can trigger assertion failures in the named daemon when...

CVE-2026-72351

A flaw was found in the Linux kernel's Generic UDP Encapsulation GUE implementation. A remote attacker could exploit a missing length validation for the remote checksum offload REMCSUM private option. By sending a specially crafted GUE packet, an attacker can cause the kernel to read beyond the...

kernel: ipv6: icmp: clear skb2->cb[] in ip6_err_gen_icmpv6_unreach()

A flaw was found in the Linux kernel's IPv6 ICMP error generation. A remote attacker could send a specially crafted IPv4 ICMP error packet with a Common Internet Protocol Security Option CIPSO IP option. This could lead to incorrect handling of packet control block data when generating an IPv6 IC...

EUVD-2026-62344

When building the iovec array for a received TLS 1.2 CBC record, ktlsocftlscbcdecrypt incremented the iovec index for every mbuf in the chain, including mbufs that were skipped because they contained only TLS header bytes. This left uninitialized entries in the iovec array. The iovec array was...
