Update Summary
This PR updates the Chainguard Wolfi base images used for building Elasticsearch Docker images:

Image	Old Digest	New Digest
chainguard-base	a7d1958	da434d8
chainguard-base-fips	0e62586	74a9124

Package Differences

chainguard-base (standard image)

Package	Old Version	New Version
glibc	2.43-r1	2.43-r2
glibc-locale-posix	2.43-r1	2.43-r2
ld-linux	2.43-r1	2.43-r2
libcrypt1	2.43-r1	2.43-r2
libgcc	15.2.0-r9	15.2.0-r11
zlib	1.3.2-r0	1.3.2-r1

chainguard-base-fips (FIPS-compliant image)

Package	Old Version	New Version
glibc	2.43-r1	2.43-r2
glibc-locale-posix	2.43-r1	2.43-r2
ld-linux	2.43-r1	2.43-r2
libcrypt1	2.43-r1	2.43-r2
libgcc	15.2.0-r9	15.2.0-r11
zlib	1.3.2-r0	1.3.2-r1

Key Observations

1. Both images have identical package changes (standard and FIPS updated in lockstep).
2. No packages were added/removed; this is purely version/revision bumps.
3. Most changes are core runtime components:
   • glibc family: 2.43-r1 � 2.43-r2 (incl. ld-linux + libcrypt1 + locale)
   • libgcc: 15.2.0-r9 � 15.2.0-r11
   • zlib: 1.3.2-r0 � 1.3.2-r1

Impact

• No failures, build scans, or other regressions were referenced in the PR conversation at time of analysis.
• Package diffs were derived by pulling the exact old/new digests and comparing apk info -v outputs.
