USTP-Secure

USTP USTP means UDP Speedy Transmission Protocol. USTP keeps the same authenticated transport model, but the project name is now simply USTP again. By default, USTP uses AEAD for DATA. It also supports an optional negotiated cleartext + HMAC mode for DATA, where payload bytes are visible on the...

CVE-2026-87724

A flaw was found in Tor. A remote attacker could exploit this vulnerability by sending a specific congestion-control CC response extension without first sending a corresponding request. This misinterpretation of the CCRESPONSE extension leads to a corrupted congestion-control state, which can cau...

CVE-2026-87724

Tor before 0.4.9.12 interprets the CCRESPONSE extension even when CCREQUEST was not sent, which allows remote attackers to cause a denial of service crash because of corrupted congestion-control state. This is TROVE-2026-032...

CVE-2026-87724

Tor versions prior to 0.4.9.12 are affected by a denial-of-service vulnerability (TROVE-2026-032) in the congestion-control mechanism. The underlying cause is that Tor interprets the CC_RESPONSE extension even when CC_REQUEST was never sent, leading to a corrupted congestion-control state and an ...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: tcp: cdg: allow tcpcdgrelease to be called multiple times Apparently, mptcp is able to call tcpdisconnect on an already disconnected flow. This is generally fine, unless current congestion control is CDG, because it might trigger...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: tcp: Fix tcpinittransfer so that icskcainitialized is not reset. This commit fixes a bug identified by syzkaller that could cause spurious double-initizations for congestion control modules. This could lead to memory leaks or oth...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: dccp: Fixed a race condition around the dp-dccpsmsscache variable. The dccpsendmsg function reads the dp-dccpsmsscache before locking the socket. The same issue occurs in dodccpgetsockopt. Added annotations for...

USN-8530-1 linux-aws, linux-aws-fips vulnerabilities

It was discovered that the Linux kernel did not properly handle shared page fragments during socket buffer operations, collectively known as Dirty Frag. A logic flaw existed in the XFRM ESP-in-TCP subsystem and in the RxRPC networking subsystem when processing paged fragments. A local attacker...

USN-8529-1: Linux kernel vulnerabilities

It was discovered that a logic flaw existed in the XFRM ESP-in-TCP subsystem in the Linux kernel when handling socket buffer fragments. This flaw is known as Fragnesia. A local attacker could use this to escalate privileges, or possibly escape a container. CVE-2026-43503 Several security issues...
