Upstream information
Description
Multiple Use-After-Free vulnerabilities were found in the add_archive_element function in ld/ldmain.c of the GNU linker (ld), a component of binutils. The root cause is that plugin_maybe_claim() in ld/plugin.c frees the original BFD object via bfd_close/_bfd_delete_bfd when entry->the_bfd->my_archive == NULL, but the caller retains both the original abfd parameter and a shallow copy (orig_input.the_bfd) as dangling pointers. These dangling pointers are subsequently dereferenced at three distinct locations in add_archive_element:1. Line ~1442: accessing abfd->my_archive via bfd_usrdata(abfd->my_archive)
2. Line ~1493: multiple accesses to abfd and abfd->my_archive in a conditional check and bfd_get_filename call
3. Line ~1525: dereferencing the shallow copy orig_input.the_bfd->my_archive in trace/verbose logging
The vulnerability is triggered when LTO plugins are active (link_info.lto_plugin_active is true) and the input object has abfd->my_archive == NULL, which is a valid state for standalone object files. Red Hat builds binutils with --enable-plugins and --enable-lto, confirming the vulnerable code path is compiled in and reachable.
An attacker who can supply a crafted object or archive file to a build process using LTO-enabled linking could exploit this flaw to cause a denial of service (linker crash via segmentation fault). Arbitrary code execution is theoretically possible through heap manipulation but is substantially mitigated by hardening measures including stack protector, FORTIFY_SOURCE, ASLR, and PIE.
The attack surface is limited to build-time environments - the linker is a development tool not exposed in production runtime. The most realistic exploitation scenario is a supply chain attack introducing a crafted object file as a build dependency in CI/CD pipelines or development environments.

Note from the SUSE Security Team on the binutils package
SUSE considers binutils a developer tool which does not receive untrusted input. Code processed by binutils is being executed in any normal scenario, so security exploits could just inject regular binary code. For this reason we update binutils only around once a year to the current stable version to catch up on features and bugfixes. If you are processing untrusted binary code with binutils we recommend doing so on a seperate system or VM. SUSE Bugzilla entry: 1275267 [CONFIRMED] No SUSE Security Announcements cross referenced.Status of this issue by product and package
