CVE-2026-68151
Description
A flaw was found in the Linux kernel's binfmt_elf_fdpic component. This component, which handles FDPIC ELF binaries, does not correctly process multiple PT_INTERP program headers. An unprivileged local attacker can exploit this by crafting a malicious binary with more than one PT_INTERP header. Successful exploitation leads to a resource leak where a file remains unwritable indefinitely, causing a denial of service.
