CVE-2026-89588

A flaw was found in the Linux kernel's Advanced Configuration and Power Interface ACPI APEI Generic Hardware Error Source GHES component. Incorrect length accounting in the gheshandlearmhwerror function can lead to the parser reading beyond the allocated memory section. This out-of-bounds read...

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-2026-89588

In the Linux kernel, the following vulnerability has been resolved: ACPI: APEI: GHES: fix ARM section length accounting after header In gheshandlearmhwerror, after skipping the cpersecprocarm header with err + 1, the remaining length was reduced by sizeoferr pointer size instead of sizeoferr...

CVE-2026-89589

In the Linux kernel, the following vulnerability has been resolved: acpi/apei/ghes: Use rawspinlockt for CXL CPER work locks The CXL CPER work registration and unregistration helpers acquire cxlcperworklock and cxlcperproterrworklock with a spinlock guard, which leaves local interrupts enabled. T...

CVE-2025-40034

In the Linux kernel, the following vulnerability has been resolved: PCI/AER: Avoid NULL pointer dereference in aerratelimit When platform firmware supplies error information to the OS, e.g., via the ACPI APEI GHES mechanism, it may identify an error source device that doesn't advertise an AER...
