Description
This security bulletin contains information about 1 vulnerability.
1) Out-of-bounds read (CVE-ID: CVE-2026-98088)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 0 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a local user to cause an out-of-bounds read.
The vulnerability exists due to improper handling of an invalid NUMA node value in _base_assign_reply_queues() when assigning high IOPS reply queues for a PCI device without NUMA-node affinity. A local user can trigger reply queue assignment to cause an out-of-bounds read.
The issue occurs when dev_to_node() returns NUMA_NO_NODE (-1).
