CVE-2025-1148
GNU Binutils ld ldelfgen.c link_order_scan memory leak
In short
GNU Binutils' linker (ld) has a memory leak in the link_order_scan function that causes it to not properly release memory during operation. While the issue itself is low-severity, it can cause the linker to consume excessive memory when processing certain inputs.
Technical detail
A memory leak exists in ld/ldelfgen.c's link_order_scan function in GNU Binutils 2.43, triggered during link order scanning operations. The vulnerability requires complex manipulation of input and has high attack complexity; exploitation is difficult but a public proof-of-concept exists. The maintainer notes all reported leaks were fixed on the master branch but withheld from 2.44 to avoid destabilization.
