USN-8597-1: Linux kernel (IBM) vulnerabilities

Maxim Suhanov discovered that the NTFS file system implementation in the Linux kernel did not properly validate file name length in certain situations, leading to an out-of-bounds read. An attacker could use this to construct a malicious NTFS image that, when mounted and operated on, could expose...

USN-8596-1: Linux kernel (NVIDIA) vulnerabilities

It was discovered that some AMD processors did not properly clear data in the floating point divider unit during speculative execution. A local attacker could use this to expose sensitive information. CVE-2025-54505 It was discovered that some AMD Zen 2 processors did not properly isolate shared...

CVE-2026-64013

A flaw was found in the Linux kernel's Advanced Configuration and Power Interface ACPI button driver. This vulnerability occurs because the ACPI General Purpose Event GPE handler is not properly removed when the driver is unloaded. An attacker could potentially trigger an ACPI notify event on a...

SUSE CVE-2026-64013

In the Linux kernel, the following vulnerability has been resolved: ACPI: button: Fix ACPI GPE handler leak during removal Commit a7e23ec17fee "ACPI: button: Install notifier for system events as well" changed the ACPI notify handler type for ACPI buttons to ACPIALLNOTIFY, but it forgot to update...

SUSE CVE-2026-64183

In the Linux kernel, the following vulnerability has been resolved: efi: Allocate runtime workqueue before ACPI init Since commit 5894cf571e14 "acpi/prmt: Use EFI runtime sandbox to invoke PRM handlers" ACPI PRM calls are delegated to a workqueue which runs in a kernel thread, making it easier to...

USN-8574-1 linux-gcp-fips vulnerabilities

CVE-2026-64183

A flaw was found in the Linux kernel's EFI Extensible Firmware Interface runtime services. This vulnerability occurs due to a NULL pointer dereference when ACPI Advanced Configuration and Power Interface PRM Platform Runtime Mechanism calls are made before the necessary workqueue is allocated. Th...

CVE-2026-64205

In the Linux kernel, the following vulnerability has been resolved: i2c: i801: fix hardware state machine corruption in error path A severe livelock and subsequent Hung Task panic were observed in the i2c-i801 driver during concurrent Fuzzing. The crash is caused by an unconditional hardware...

CVE-2026-64183

The CVE-2026-64183 issue affects the Linux kernel EFI runtime, specifically PRM calls, which could NULL-deref if PRM accesses occur before the EFI workqueue is allocated. The root cause is early ACPI PRM access during init before efisubsys_init() runs and before the runtime workqueue exists. The ...
