CVE-2026-98291

A flaw was found in the Linux kernel's Intel Bluetooth PCIe driver (btintel_pcie). An off-by-one bounds checking error during receive queue handling allows an index to reference one element past the allocated array boundaries. A local user could exploit this flaw to cause a Denial of Service (DoS) through a kernel crash or potentially corrupt system memory.

This vulnerability is classified as Moderate impact for Red Hat products because exploitation requires local system access, low-privilege authentication, and the presence of specific Intel PCIe Bluetooth hardware controllers. While successful exploitation could result in kernel memory corruption or a denial of service, typical enterprise and cloud server installations do not feature or enable Bluetooth interfaces. Consequently, the operational blast radius is constrained to localized client or workstation environments running the affected hardware driver.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
