CVE-2026-23352

A flaw was found in the Linux kernel. During system startup, when the kernel attempts to free memory used by EFI Extensible Firmware Interface boot services, it may fail to properly release these memory regions. This occurs because the memory freeing process is initiated before the system's memor...
