In the Linux kernel, the following vulnerability has been resolved: host1x: bus: Fix missing ops null check in error teardown In… (CVE-2026-98876)

The Linux kernel host1x driver had a flaw in the host1x_device_init() function where error teardown paths did not verify that client->ops was non-NULL before dereferencing it. This missing null check could lead to a NULL pointer dereference if client->ops was NULL. The forward initialization paths correctly checked client->ops, but the error teardown paths did not. The fix involved adding the missing client->ops check in both the teardown and teardown_late labels to prevent dereferencing a NULL pointer.

This vulnerability can cause a NULL pointer dereference in the Linux kernel, leading to a kernel crash or denial of service. There is no indication of code execution or privilege escalation from the provided data.

A fix has been implemented to add the missing null check for client->ops in the error teardown paths. Users should apply the official Linux kernel update that includes this fix once available. Patch status is not explicitly confirmed in the provided data; check the vendor advisory for current remediation guidance.
