Ubuntu 18.04 LTS / 20.04 LTS : Linux kernel vulnerabilities (USN-8389-1)

The remote Ubuntu 18.04 LTS / 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8389-1 advisory. It was discovered that the Linux kernel did not properly handle shared page fragments during socket buffer operations, collectively known as...

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...

kernel: net: skbuff: propagate shared-frag marker through frag-transfer helpers

A flaw was found in the Linux kernel's networking skbuff component. When skbtrycoalesce attaches paged fragments, it can lose the SKBFLSHAREDFRAG marker. This can lead to the Encapsulating Security Payload ESP input decrypting data in place over page-cache backed fragments, potentially resulting ...

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...
