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...

PT-2026-79097

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-incomplete frames without enforcing a total message-size limit. An unauthenticated remote client can repeatedly send fragmented WebSocket...

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...

CVE-2026-49423

FreeBSD 's KTLS (Kernel TLS) subsystem contains an uninitialized memory access in ktls_ocf_tls_cbc_decrypt(). When building the iovec array for a received TLS 1.2 CBC record, the function incremented the index for every mbuf in the chain, including those skipped because they held only the 5-byte ...

CVE-2026-49423 Remote DOS via uninitialized memory access in KTLS receive

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...

Microsoft Visual Studio Products (August 2026)

The Microsoft Visual Studio Products are missing security updates. It is, therefore, affected by multiple vulnerabilities: - Out-of-bounds write in .NET allows an unauthorized attacker to execute code locally. CVE-2026-62871 - Unchecked input for loop condition in .NET allows an unauthorized...

ROS-20260819-73-0069

The vulnerability of the ipv6getdataprimitive function in the libnetutil/netutil.cc library, a networking scanning tool for Nmap, is related to a countable loss of significance. Exploiting this vulnerability could allow a remote attacker to cause a service failure...
