    Changes in apptainer:

    - Update to version 1.5.3:
      * If the ptrace() system call does not work while building an image as
        an unprivileged user, skip using PRoot to preserve file ownership and
        print an INFO message.
      * Bind getopt from the host when using fakeroot command mode, to make
        the fakeroot command work with base containers which no longer contain
        getopt by default.
      * Update fixes CVE-2026-56852 (GO-2026-5970) (bsc#1272115)
        golang.org/x/text/unicode/norm:
        A norm.Iter can enter an infinite loop when handling input
        containing invalid UTF-8 bytes.

    - Update to version 1.5.2:
      * Extended the mksquashfs segmentation fault workaround for cases
        where mksquashfs uses many processor cores.

    - Update the golang.org/x/net dependency to version v0.57.0
      to fix CVE-2026-39821 for good (bsc#1266656).
      The fix in v0.55.0 only applied to Unicode versions >=16.0.0
      which aren't yet available on any Golang versions released.

Tenable has extracted the preceding description block directly from the SUSE security advisory.
