CVE-2026-74352 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.17% chance of exploitation in the next 30 days.
