CVE-2026-68151

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> binfmt_elf_fdpic: only honour the first PT_INTERP<br /> <br /> The program header scan handles PT_INTERP from a switch nested in the<br /> scan loop, so its break leaves the switch and not the loop. A binary<br /> carrying more than one PT_INTERP runs the case again and overwrites both<br /> interpreter_name and interpreter. The previous name allocation leaks and<br /> so does the previous interpreter reference, along with the write denial<br /> open_exec() took on it. The denial is never released, so the file stays<br /> unwritable for as long as the system runs.<br /> <br /> An unprivileged caller reaches this with a crafted binary and repeats it<br /> at will. binfmt_elf stops at the first PT_INTERP. Do the same here.<br /> <br /> The flaw dates back to the driver&amp;#39;s introduction in the pre-git history<br /> tree introduced in v2.6.11 by 91808d6ebe39 ("[PATCH] FRV: Add FDPIC ELF<br /> binary format driver").
