CVE-2026-89570
A flaw was found in the Linux kernel's Compute Express Link CXL subsystem. Lifetime issues with the CXL Machine Check Exception MCE notifier can lead to NULL dereferences and use-after-free vulnerabilities in the MCE handler. This could allow an attacker to cause system instability or a denial of...
CVE-2026-89731
A flaw was found in the Linux kernel. A vulnerability exists in the cxlrchgetaerinfo function, which is responsible for handling CXL/RAS Compute Express Link/Reliability, Availability, and Serviceability AER Advanced Error Reporting capabilities. Due to a mismatch between a software structure and...
CVE-2026-89589
A flaw was found in the ACPI/APEI/GHES component of the Linux kernel. Incorrect usage of spinlocks in the CXL CPER work registration and unregistration helpers can lead to a deadlock. If a CPU holds a lock while a GHES interrupt arrives on the same CPU, the interrupt handler will spin on the held...
CVE-2026-89571
A flaw was found in the Linux kernel's CXL Compute Express Link features. A local attacker could exploit an out-of-bounds read vulnerability in the fwctlcmdrpc and cxlctlsetfeature functions. This occurs when the system attempts to copy data with a small input buffer length but processes a larger...
