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-2026-89547

CVE-2026-89547 affects the Linux kernel's SUNRPC component. The function __svc_create() initializes three per-pool percpu_counter statistics but ignores all return values. On SMP systems, if percpu_counter_init() fails due to a per-cpu allocation failure (e.g., under memory pressure or fault inje...

CVE-2026-89514

In the Linux kernel , the scsi: fnic driver's fnic_fcoe_process_vlan_resp() function allocates a VLAN descriptor using kzalloc_obj() with the default GFP_KERNEL flag while holding vlans_lock via spin_lock_irqsave(). Since GFP_KERNEL may sleep, this is invalid in the atomic context and can trigger...
