🛡️ USN-8462-1 — linux-oracle-5.15

linux-oracle-5.15 vulnerabilities

It was discovered that the Linux kernel algif_aead 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 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 could use this to escalate privileges, or possibly escape a

container. (CVE-2026-43284, CVE-2026-43500)

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,

CVE-2026-46300)

Qualys discovered that a race condition existed in the ptrace subsystem of

the Linux kernel when privileged processes are exiting. An unprivileged

local attacker could use this issue to expose sensitive information.

(CVE-2026-46333)

Several security issues were discovered in the Linux kernel.

An attacker could possibly use these to compromise the system.

This update corrects flaws in the following subsystems:

• Cryptographic API;
• Ethernet bonding driver;
• Packet sockets;
• RDS protocol;
• TLS protocol;
