How to fix?

Upgrade SLES:15.1 binutils-devel to version 2.32-7.5.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream binutils-devel package and not the binutils-devel package as distributed by SLES. See How to fix? for SLES:15.1 relevant fixed versions and status.

An issue was discovered in the merge_strings function in merge.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31. There is a NULL pointer dereference in _bfd_add_merge_section when attempting to merge sections with large alignments. A specially crafted ELF allows remote attackers to cause a denial of service, as demonstrated by ld.
