Ubuntu 22.04 LTS USN-6795-1 Critical: Kernel Denial Of Service Threats

Several security issues were fixed in the Linux kernel.. ========================================================================== Ubuntu Security Notice USN-6795-1 May 28, 2024 linux-intel-iotg vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 22.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-intel-iotg: Linux kernel for Intel IoT platforms Details: Zheng Wang discovered that the Broadcom FullMAC WLAN driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability. A physically proximate attacker could possibly use this to cause a denial of service (system crash). (CVE-2023-47233) It was discovered that the Open vSwitch implementation in the Linux kernel could overflow its stack during recursive action operations under certain conditions. A local attacker could use this to cause a denial of service (system crash). (CVE-2024-1151) Sander Wiebing, Alvise de Faveri Tron, Herbert Bos, and Cristiano Giuffrida discovered that the Linux kernel mitigations for the initial Branch History Injection vulnerability (CVE-2022-0001) were insufficient for Intel processors. A local attacker could potentially use this to expose sensitive information. (CVE-2024-2201) 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: - PowerPC architecture; - S390 architecture; - Core kernel; - Block layer subsystem; - Android drivers; - Power management core; - Bus devices; -Hardware random number generator core; - Cryptographic API; - Device frequency; - DMA engine subsystem; - ARM SCMI message protocol; - GPU drivers; - HID subsystem; - Hardware monitoring drivers; - I2C subsystem; - IIO ADC drivers; - IIO subsystem; - IIO Magnetometer sensors drivers; - InfiniBand drivers; - Media drivers; - Network drivers; - PCI driver for MicroSemi Switchtec; - PHY drivers; - SCSI drivers; - DesignWare USB3 driver; - BTRFS file system; - Ceph distributed file system; - Ext4 file system; - F2FS file system; - JFS file system; - NILFS2 file system; - NTFS3 file system; - Pstore file system; - SMB network file system; - Memory management; - CAN network layer; - Networking core; - HSR network protocol; - IPv4 networking; - IPv6 networking; - Logical Link layer; - MAC80211 subsystem; - Multipath TCP; - Netfilter; - NFC subsystem; - SMC sockets; - Sun RPC protocol; - TIPC protocol; - Unix domain sockets; - Tomoyo security module; - Realtek audio codecs; (CVE-2023-52616, CVE-2024-26679, CVE-2024-26608, CVE-2023-52594, CVE-2024-26622, CVE-2023-52643, CVE-2024-26594, CVE-2023-52598, CVE-2023-52627, CVE-2023-52491, CVE-2024-26592, CVE-2024-26717, CVE-2023-52638, CVE-2024-26704, CVE-2023-52637, CVE-2024-26645, CVE-2023-52602, CVE-2024-26722, CVE-2024-26671, CVE-2023-52599, CVE-2024-26720, CVE-2023-52631, CVE-2023-52486, CVE-2024-26640, CVE-2023-52606, CVE-2023-52633, CVE-2024-26593, CVE-2024-26664, CVE-2023-52618, CVE-2024-26625, CVE-2023-52604, CVE-2024-26695, CVE-2024-26644, CVE-2024-26826, CVE-2024-26600, CVE-2024-26808, CVE-2023-52619, CVE-2023-52597, CVE-2024-26602, CVE-2024-26635, CVE-2023-52623, CVE-2024-26665, CVE-2024-26916, CVE-2024-26689, CVE-2023-52635, CVE-2024-26712, CVE-2023-52614, CVE-2024-26606, CVE-2024-26610, CVE-2024-26675, CVE-2023-52617, CVE-2024-26697, CVE-2023-52595, CVE-2023-52494,CVE-2024-26641, CVE-2024-26698, CVE-2024-26707, CVE-2024-26673, CVE-2023-52493, CVE-2024-26676, CVE-2024-26910, CVE-2023-52601, CVE-2024-26660, CVE-2023-52608, CVE-2024-26615, CVE-2023-52587, CVE-2024-26825, CVE-2023-52498, CVE-2023-52492, CVE-2024-26668, CVE-2024-26715, CVE-2024-26685, CVE-2024-26702, CVE-2024-26663, CVE-2024-26636, CVE-2024-26627, CVE-2024-26696, CVE-2023-52583, CVE-2023-52642, CVE-2023-52489, CVE-2024-26614, CVE-2024-26829, CVE-2024-26684, CVE-2023-52615, CVE-2023-52435, CVE-2023-52530, CVE-2023-52607, CVE-2024-26920, CVE-2023-52622, CVE-2023-52588) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 22.04 LTS linux-image-5.15.0-1057-intel-iotg 5.15.0-1057.63 linux-image-intel-iotg 5.15.0.1057.57 After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
