Doc Text:
A flaw was found in the Linux kernel's platform/x86/intel/tpmi component. This vulnerability occurs due to improper memory deallocation within the mem_write() function, where a temporary array was not consistently released on all exit paths. This could lead to a memory leak, potentially impacting system stability or resource availability over time.

Description OSIDB Bzimport 2026-08-15 06:06:49 UTC 
In the Linux kernel, the following vulnerability has been resolved:

platform/x86/intel/tpmi: use cleanup helpers in mem_write()

In mem_write(), the temporary array returned by
parse_int_array_user() must be released on all exit paths.
Convert the array variable to use cleanup.h scope-based
cleanup so it is freed automatically on return.

This also moves the array declaration next to
parse_int_array_user() as required by cleanup.h usage
guidelines.
