kernel: "Fragnesia" is a variant of Dirty Frag vulnerability in the ESP/XFRM leading to Local Privilege Escalation (LPE) vulnerability in the Linux kernel

A flaw was found in the Linux kernel's XFRM ESP-in-TCP subsystem. Unsafe in-place cryptographic processing allows a low-privileged local attacker to write arbitrary bytes into the page cache of read-only files, including sensitive system files. An attacker can exploit this to overwrite privileged...

USN-8391-1 linux-raspi, linux-raspi-5.4 vulnerabilities

It was discovered that the Linux kernel algifaead module did not properly handle in-place cryptographic operations. This flaw is known as Copy Fail. A local attacker could use this to escalate privileges, or possibly escape a container. CVE-2026-31431 It was discovered that the Linux kernel did n...

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...

CVE-2026-25550 Seagull Software BarTender Unauthenticated RCE via .NET Remoting Service

Seagull Software BarTender 2010, 2016, and 2019 contain an unauthenticated remote code execution vulnerability in the .NET Remoting service exposed on TCP port 7375 via BtSystem.Service.exe. The service registers an unauthenticated singleton endpoint — BarTenderSystem for BarTender 2016 = R9, and...

Memory exhaustion in HTTP header parser

Impact If this library is used to implement a WebSocket server on top of a TCP server rather than an HTTP server or framework using the WebSocket::Driver.server method, or, if it is used to complement a WebSocket client, then a peer can make a single connection consume an unbounded amount of memo...

In the Linux kernel, the following vulnerability has been resolved: mptcp: pm: ADDADDR rtx: fix potential data-race This mptcppmaddtimer helper is executed as a timer callback in softirq context. To avoid any data races, the socket lock needs to be held with bhlocksock. If the socket is in use,...

SUSE CVE-2026-46158

In the Linux kernel, the following vulnerability has been resolved: mptcp: pm: ADDADDR rtx: always decrease sk refcount When an ADDADDR is retransmitted, the sk is held in skresettimer. It should then be released in all cases at the end. Some unlikely checks were returning directly instead of...

SUSE CVE-2026-46168

In the Linux kernel, the following vulnerability has been resolved: mptcp: fix scheduling with atomic in timestamp sockopt Using locksockfast atomic context around socksettimestamp and socksettimestamping is unsafe, as both helpers can sleep. Replace locksockfast with sleepable locksock/releaseso...

SUSE CVE-2026-46170

In the Linux kernel, the following vulnerability has been resolved: mptcp: pm: ADDADDR rtx: free sk if last When an ADDADDR is retransmitted, the sk is held in skresettimer, and released at the end. If at that moment, it was the last reference being held, the sk would not be freed. sockput should...
