The fix
We hold no Microsoft remediation data for CVE-2026-90238, which normally means it is not a Windows CVE. For non-Microsoft software the fix is the vendor's own updated release, and the affected versions are listed below.
What it is
In the Linux kernel, the following vulnerability has been resolved: media: amd: isp4: fix self-deadlock in isp4sd_pwron_and_init() error path isp4sd_pwron_and_init() holds ops_mutex via guard(mutex) and, on any init failure, jumps to err_deinit and calls isp4sd_pwroff_and_deinit(). That helper takes the same ops_mutex, re-acquiring a non-recursive mutex already held by the current thread, so any init failure deadlocks. Unwind the error path in stages instead, releasing only what each failure point acquired. This also avoids the issues that an unconditional teardown would hit at the earlier failures, such as a runtime-PM underflow from pm_runtime_resume_and_get() and MMIO access while the device is unpowered.
