Overview
CVE-2026-74352 is a known-severity vulnerability. It was published on August 15, 2026.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
of: reserved_mem: avoid post-init UAF when alloc_reserved_mem_array() fails
The global pointer 'reserved_mem' continues to reference the
reserved_mem_array which lives in __initdata if
alloc_reserved_mem_array() fails. of_reserved_mem_lookup() is
exported for post-init use, that would dereference freed memory
and trigger a use-after-free.
So reset reserved_mem_count to 0 when alloc_reserved_mem_array()
fails.
