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-2026-89589

CVE-2026-89589 affects the Linux kernel in the acpi/apei/ghes subsystem, specifically the CXL CPER work registration and unregistration helpers. The root cause is a deadlock : the CXL CPER work locks are acquired with a regular spinlock guard (interrupts enabled) in register/unregister paths, whi...

CVE-2026-89588

CVE-2026-89588 affects the Linux kernel ACPI APEI GHES subsystem. In ghes_handle_arm_hw_error(), after skipping the cper_sec_proc_arm header, the remaining length was incorrectly reduced by sizeof(err) (the pointer size ) instead of sizeof(*err) (the structure size ). This overestimates the avail...

Unity Linux 20.1050a Security Update: kernel (UTSA-2026-100376)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-100376 advisory. In the Linux kernel, the following vulnerability has been resolved: EFI/CPER: don't go past the ARM processor CPER record buffer There's a logic inside GHES/CPER to...

The vulnerability of EFI/CPER components in Linux kernel allows a hacker to trigger a service failure.

The vulnerability of EFI/CPER components in Linux kernel is related to errors in processing parameter length. Exploiting this vulnerability can allow an attacker to cause a service failure...

CVE-2026-43266

A flaw was found in the Linux kernel's handling of Common Platform Error Records CPER for ARM processors. This vulnerability allows a local attacker or malicious firmware to provide a malformed CPER record with an excessively large section length. The kernel then attempts to read data beyond the...

CVE-2026-43266

In the Linux kernel, the following vulnerability has been resolved: EFI/CPER: don't go past the ARM processor CPER record buffer There's a logic inside GHES/CPER to detect if the sectionlength is too small, but it doesn't detect if it is too big. Currently, if the firmware receives an ARM process...

CVE-2026-43171

In the Linux kernel, the following vulnerability has been resolved: EFI/CPER: don't dump the entire memory region The current logic at cperprintfwerr doesn't check if the error record length is big enough to handle offset. On a bad firmware, if the ofset is above the actual record, length -= offs...

CVE-2026-43277

The CVE-2026-43277 issue affects the Linux kernel GHES/APEI path. The root cause is a mismatch between CPER-record length and the actual number of pages allocated when ghes_new() validates CPER data, enabling a bad firmware to cause an out-of-bounds write and a kernel OOPs/panic. Public descripti...
