CVE-2026-23352

CVE-2026-23352 affects Linux kernel's x86 EFI code: efi_free_boot_services() defers freeing of EFI_BOOT_SERVICES memory, but memblock_free_late() is not suitable for reserved memory and may miss uninitialized memory maps when CONFIG_DEFERRED_STRUCT_PAGE_INIT=y. This can cause a RAM leak (~140 MB ...
