+Subject: [PATCH] Harden peerDigestSwapInMask against invalid cache digest
+ reply (#2423)
+
+A cache_digest on-the-wire size may be bigger than the
+mask_size declared in the digest itself.
+
+Ignore the digest in case this happens.
+
+CVE: CVE-2026-50012
+Upstream-Status: Backport [https://github.com/squid-cache/squid/commit/19fcfe922717c8b255270c032dcde4071c003bcd]

+Subject: [PATCH] Fix -Wsign-compare on arm32 (#2432)
+
+Due to ssize_t differences on 32/64 bit platforms, changes
+to peerDigestSwapInMask in commit 556b91a8a7 cause
+signedness comparison errors.
+Refactor to be safe both on 32- and 64-bit platforms
