+Subject: [PATCH] PR32560 stack-buffer-overflow at objdump disassemble_bytes
+
+There's always someone pushing the boundaries.
+
+        PR 32560
+        * objdump.c (MAX_INSN_WIDTH): Define.
+        (insn_width): Make it an unsigned long.
+        (disassemble_bytes): Use MAX_INSN_WIDTH to size buffer.
+        (main <OPTION_INSN_WIDTH>): Restrict size of insn_width.
+
+CVE: CVE-2025-0840
+Upstream-Status: Backport [https://sourceware.org/git/?p=binutils-gdb.git;a=commitdiff;h=baac6c221e9d69335bf41366a1c7d87d8ab2f893]
