This issue may allow a malicious user to cause a use-after-free and double-free problem, which may permit remote code execution or lead to local privilege escalation. ## Affected - `linux_kernel >= 5.0, < 5.4.260` - `linux_kernel >= 5.5, < 5.10.199` - `linux_kernel >= 5.11, < 5.15.137` - `linux_kernel >= 5.16, < 6.1.60` - `linux_kernel >= 6.2, < 6.5.9` - `enterprise_linux = 8.0` - `enterprise_linux = 9.0` - `active_iq_unified_manager` - `solidfire_&_hci_management_node` - `solidfire_&_hci_storage_node` ## Remediation Upgrade past the affected range: - `linux_kernel 6.5.9`
