security advisorycriticalUbuntuUbuntu 24.04 LTS linux-xilinx Critical Escalation Threats USN-8499-1
Several security issues were fixed in the Linux kernel.. ========================================================================== Ubuntu Security Notice USN-8499-1 July 02, 2026 linux-xilinx vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 24.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-xilinx: Linux kernel for Xilinx systems Details: 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, CVE-2026-45998, CVE-2026-46000) 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) Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contain a memory leak when handling AppArmor notifications. A local attacker could use this to cause resource exhaustion. (CVE-2026-47326) Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contain a NULL pointerdereference when handling AppArmor notifications. A local attacker could use this to cause a kernel oops. (CVE-2026-47327) Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained an invalid free when handling AppArmor notifications. A local attacker could use this to corrupt kernel memory. (CVE-2026-47328) Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained insufficient validation of AppArmor notification responses. A local attacker could use this to allow crafted responses to be processed. (CVE-2026-47329) Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 used an uninitialized variable when handling AppArmor notifications. A local attacker could use this to cause incorrect caching of data. (CVE-2026-47330) Tristan Madani discovered that Ubuntu Linux kernel 6.8 contained a use- after-free (UAF) bug. A local attacker could use this to cause memory corruption and, theoretically, arbitrary code execution. (CVE-2026-47331) Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained an out-of-bounds (OOB) read when handling AppArmor notifications. A local attacker could use this to cause information disclosure of kernel memory. (CVE-2026-47332) Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained a out-of-bounds (OOB) read when handling AppArmor notifications. A local attacker could use this to cause kernel memory corruption and, theoretically, influence processing of AppArmor policies. (CVE-2026-47333) Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained incorrect holding of locks when handling AppArmor notifications. A local attacker could use this to cause a kernel panic or deadlock. (CVE-2026-47334) Tristan Madani discovered that Ubuntu Linux kernel 6.8 contained a NULL pointer dereference when handling AppArmor notifications. A local attacker could use this to cause a kernel panic. (CVE-2026-47335) Tristan Madani discovered that Ubuntu Linux kernel 6.8 usedan uninitialized variable when handling AppArmor AF_INET/AF_INET6 socket mediation. A local attacker could use this to influence processing of fine- grained network socket mediation. (CVE-2026-47336) Tristan Madani and Trevor Lawrence have each independently discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained a NULL pointer dereference when handling AppArmor network socket mediation. A local attacker could use this to cause a kernel oops. (CVE-2026-47337) Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

system to the following package versions: Ubuntu 24.04 LTS linux-image-6.8.0-1032-xilinx 6.8.0-1032.33 linux-image-xilinx 6.8.0.1032.33 linux-image-xilinx-6.8 6.8.0.1032.33 linux-image-xilinx-zynqmp 6.8.0.1032.33 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.

Software Description: - linux-raspi: Linux kernel for Raspberry Pi systems - linux-raspi-5.4: Linux kernel for Raspberry Pi systems Details: 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) 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; - Network drivers; - NVME drivers; - IPv4 networking; - Packet sockets; - RDS protocol; - TLS protocol; (CVE-2024-50304, CVE-2026-23112, CVE-2026-23209, CVE-2026-31504, CVE-2026-31533, CVE-2026-43033, CVE-2026-43077, CVE-2026-43078, CVE-2026-43494, CVE-2026-46028) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 20.04 LTS linux-image-5.4.0-1143-raspi 5.4.0-1143.156 Available with Ubuntu Pro linux-image-raspi 5.4.0.1143.174 Available with Ubuntu Pro linux-image-raspi-5.4 5.4.0.1143.174 Available with Ubuntu Pro linux-image-raspi2 5.4.0.1143.174 Available with Ubuntu Pro Ubuntu 18.04 LTS linux-image-5.4.0-1143-raspi 5.4.0-1143.156~18.04.1 Available with Ubuntu Pro linux-image-raspi-5.4 5.4.0.1143.156~18.04.1 Available with Ubuntu Pro linux-image-raspi-hwe-18.04 5.4.0.1143.156~18.04.1 Available with Ubuntu Pro After a standard system update you need to reboot your computer to make all the necessary changes.
