NewCVE-2026-98088 (opens in a new tab)How to fix?
Upgrade Oracle:9 kernel-uek-debug-modules-usb to version 0:6.12.0-207.111.5.1.el9uek or higher.
This issue was patched in ELSA-2026-500374.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-uek-debug-modules-usb package and not the kernel-uek-debug-modules-usb package as distributed by Oracle.
See How to fix? for Oracle:9 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
scsi: mpt3sas: Avoid out-of-bounds cpumask_of_node() call in _base_assign_reply_queues()
dev_to_node() can return NUMA_NO_NODE (-1) on systems without NUMA topology information for the PCI device, such as single-socket boards that don't expose device-to-node affinity. Passing -1 directly into cpumask_of_node() indexes node_to_cpumask_map[-1], an out-of-bounds array read caught by UBSAN:
UBSAN: array-index-out-of-bounds in arch/x86/include/asm/topology.h:72:28 index -1 is out of range for type 'cpumask *[1024]'
Fall back to cpu_online_mask when no NUMA node is available, rather than assuming dev_to_node() always returns a valid node index.
