Linux Distros Unpatched Vulnerability : CVE-2026-53042

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - fwctl: Fix class init ordering to avoid NULL pointer dereference on device removal CXL is linked before fwctl in drivers/Makefile. Both use moduleinit, so...

CVE-2026-53042

A flaw was found in the Linux kernel's fwctl module. An issue with the class initialization ordering can lead to a null pointer dereference when a device is removed. This can cause a system crash, resulting in a Denial of Service DoS...

CVE-2026-53042

In CVE-2026-53042, the Linux kernel vulnerability stems from an initialization order: CXL is linked before fwctl in drivers/Makefile, causing fwctl_register to run before fwctl_init, so fwctl_class isn’t registered when device_add is called. This makes class_to_subsys() return NULL, skipping knod...

CVE-2023-3494

The fwctl driver implements a state machine which is executed when a bhyve guest accesses certain x86 I/O ports. The interface lets the guest copy a string into a buffer resident in the bhyve process' memory. A bug in the state machine implementation can result in a buffer overflowing when copyin...
