high Nessus Plugin ID 196947

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6767-2 advisory.

Chenyuan Yang discovered that the RDS Protocol implementation in the Linux kernel contained an out-of- bounds read vulnerability. An attacker could use this to possibly cause a denial of service (system crash). (CVE-2024-23849)

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:

- ARM64 architecture;

- PowerPC architecture;

- S390 architecture;

- Block layer subsystem;

- Android drivers;

- Hardware random number generator core;

- GPU drivers;

- Hardware monitoring drivers;

- I2C subsystem;

- IIO Magnetometer sensors drivers;

- InfiniBand drivers;

- Network drivers;

- PCI driver for MicroSemi Switchtec;

- PHY drivers;

- Ceph distributed file system;

- Ext4 file system;

- JFS file system;

- NILFS2 file system;

- Pstore file system;

- Core kernel;

- Memory management;

- CAN network layer;

- Networking core;

- IPv4 networking;

- Logical Link layer;

- Netfilter;

- NFC subsystem;

- SMC sockets;

- Sun RPC protocol;

- TIPC protocol;

- Realtek audio codecs; (CVE-2024-26696, CVE-2023-52583, CVE-2024-26720, CVE-2023-52615, CVE-2023-52599, CVE-2023-52587, CVE-2024-26635, CVE-2024-26704, CVE-2024-26625, CVE-2024-26825, CVE-2023-52622, CVE-2023-52435, CVE-2023-52617, CVE-2023-52598, CVE-2024-26645, CVE-2023-52619, CVE-2024-26593, CVE-2024-26685, CVE-2023-52602, CVE-2023-52486, CVE-2024-26697, CVE-2024-26675, CVE-2024-26600, CVE-2023-52604, CVE-2024-26664, CVE-2024-26606, CVE-2023-52594, CVE-2024-26671, CVE-2024-26598, CVE-2024-26673, CVE-2024-26920, CVE-2024-26722, CVE-2023-52601, CVE-2024-26602, CVE-2023-52637, CVE-2023-52623, CVE-2024-26702, CVE-2023-52597, CVE-2024-26684, CVE-2023-52606, CVE-2024-26679, CVE-2024-26663, CVE-2024-26910, CVE-2024-26615, CVE-2023-52595, CVE-2023-52607, CVE-2024-26636)
