Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the BPF sock ops program when accessing ctx fields where the destination register dst reg is the same as the source register src reg. In the !fullsock or !locked tcp...

CVE-2026-7664

IBM Langflow OSS 1.0.0 through 1.8.4 could allow unauthenticated attackers to access protected MCP project resources and execute MCP operations due to improper authorization enforcement in the Streamable MCP transport endpoint...

kernel: sctp: revalidate list cursor after sctp_sendmsg_to_asoc() in SCTP_SENDALL

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. A race condition exists in the SCTPSENDALL path where a cached list entry is not properly revalidated after the socket lock is temporarily released. This allows a local attacker or a remote attacker v...

CVE-2026-49357

CVE-2026-49357 affects line-desktop-mcp (LINE Desktop MCP). In --http-mode, the MCP server binds to 0.0.0.0 and exposes the /mcp endpoint without MCP authentication, enabling any network client on the port to initialize a session, list tools, and call tools that read LINE Desktop chat history or ...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Net: Ethernet: Cortina: Use TOE/TSO for all TCP protocols. It is desirable to enable the hardware accelerator to also process non-segmented TCP frames. We can pass the skb-len value to the “TOE/TSO” offloader, which will handle...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

A out-of-bounds read vulnerability was discovered in the NVMe-oF/TCP subsystem within the Linux kernel. This issue may allow a remote attacker to send a specially crafted TCP packet, triggering a heap-based buffer overflow. As a result, data from kmalloc will be printed, and it may also be leaked...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: mptcp: Fixed an out-of-bounds error during the parsing of TCP options. The TCP option parser in mptcp mptcpgetoptions could read one byte out of bounds. When the length of the option is 1, the execution flow enters a loop, reads...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Net: Properly handles tunneled traffic when using GSO fallback for IPV6CSUM. NETIFFIPV6CSUM only indicates support for packet checksum offloading without IPv6 extension headers. Packets with extension headers must rely on...

Astra Linux – Vulnerabilities in Linux, Linux-5.15, Linux-5.10

A vulnerability, classified as problematic, was discovered in the Linux kernel. This vulnerability affects the tcpgetsockopt/tcpsetsockopt functions of the TCP Handler component. Manipulation of these functions can lead to a race condition. It is recommended that a patch be applied to address thi...

Astra Linux – Vulnerability in connman

A issue was discovered in the DNS proxy of Connman through version 1.40. The implementation of the TCP server’s reply mechanism lacks a check to ensure that there is sufficient Header Data, resulting in an out-of-bounds read...

Astra Linux – Vulnerability in Linux 5.15

The Linux kernel’s NFSD implementation before versions 5.19.17 and 6.0.2 is vulnerable to buffer overflow attacks. NFSD tracks the number of pages held by each NFSD thread by combining the receive and send buffers of a remote procedure call RPC into a single array of pages. A client can force the...
