USN-8501-1 linux 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...
Ubuntu 20.04 LTS : Linux kernel (Oracle) vulnerabilities (USN-8462-1)
The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8462-1 advisory. 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...
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...
Ubuntu 14.04 LTS / 18.04 LTS : Linux kernel vulnerability (USN-8390-1)
The remote Ubuntu 14.04 LTS / 18.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-8390-1 advisory. It was discovered that the Linux kernel did not properly handle shared page fragments during socket buffer operations, collectively known as Dirty Fra...
