PR binutils/22875: Visium/ELF: Prevent an out-of-bounds howto table access
Prevent an out-of-bounds `visium_elf_howto_table' table access in `visium_info_to_howto_rela' by using the size of the table rather than R_VISIUM_max to determine the number of entries in the contiguous regular Visium relocation range defined and described in the table. bfd/ * elf32-visium.c (visium_info_to_howto_rela): Correct the range check for `visium_elf_howto_table' table access.
