This flaw allows a local user to crash or escalate their privileges on the system. ## Affected - `linux_kernel >= 5.10, < 5.15.37` - `linux_kernel >= 5.16, < 5.16.11` - `fedora = 34` - `fedora = 35` - `h300e_firmware` - `h300s_firmware` - `h410c_firmware` - `h410s_firmware` - `h500e_firmware` - `h500s_firmware` - `h700e_firmware` - `h700s_firmware` ## Remediation Upgrade past the affected range: - `linux_kernel 5.16.11` ## Vendor advisories - **RHSA-2024:0724** · Red Hat · fixed in: Red Hat Virtualization 4 Hypervisor for RHEL 8, Red Hat Enterprise Linux BaseOS EUS (v.8.6), Red Hat CodeReady Linux Builder EUS (v.8.6) · released 2024-02-07 · [advisory](https://access.redhat.com/errata/RHSA-2024:0724) - **RHSA-2024:3138** · Red Hat · fixed in: Red Hat Enterprise Linux BaseOS (v. 8), Red Hat Enterprise Linux CRB (v. 8) · released 2024-05-22 · [advisory](https://access.redhat.com/errata/RHSA-2024:3138) - **RHSA-2024:10262** · Red Hat · fixed in: Red Hat Enterprise Linux BaseOS EUS (v.8.8), Red Hat CodeReady Linux Builder EUS (v.8.8) · released 2024-11-26 · [advisory](https://access.redhat.com/errata/RHSA-2024:10262) - **RHSA-2024:2950** · Red Hat · fixed in: Red Hat Enterprise Linux NFV (v. 8), Red Hat Enterprise Linux RT (v. 8) · released 2024-05-22 · [advisory](https://access.redhat.com/errata/RHSA-2024:2950) - **Red Hat VEX** · Moderate · affected: Red Hat Enterprise Linux 9 · no fix planned: Red Hat Enterprise Linux 9 · updated 2026-10-09 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2022/cve-2022-0500.json)
