+Subject: [PATCH] PR 33452 SEGV in bfd_elf_gc_record_vtentry
+
+Limit addends on vtentry relocs, otherwise ld might attempt to
+allocate a stupidly large array.  This also fixes the expression
+overflow leading to pr33452.  A vtable of 33M entries on a 64-bit
+host is surely large enough, especially considering that VTINHERIT
+and VTENTRY relocations are to support -fvtable-gc that disappeared
+from gcc over 20 years ago.
+
+	PR ld/33452
+	* elflink.c (bfd_elf_gc_record_vtentry): Sanity check addend.
+
+CVE: CVE-2025-11412
+Upstream-Status: Backport [https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=047435dd988a3975d40c6626a8f739a0b2e154bc]
