+Subject: [PATCH] html: impose open element stack size limit
+
+The HTML specification contains a number of algorithms which are
+quadratic in complexity by design. Instead of adding complicated
+workarounds to prevent these cases from becoming extremely expensive in
+pathological cases, we impose a limit of 512 to the size of the stack of
+open elements. It is extremely unlikely that non-adversarial HTML
+documents will ever hit this limit (but if we see cases of this, we may
+want to make the limit configurable via a ParseOption).
+
+Thanks to Guido Vranken and Jakub Ciolek for both independently
+reporting this issue.
+
+Fixes CVE-2025-47911
+Fixes golang/go#75682

+Subject: [PATCH] html: align in row insertion mode with spec
+
+Update inRowIM to match the HTML specification. This fixes an issue
+where a specific HTML document could cause the parser to enter an
+infinite loop when trying to parse a </tbody> and implied </tr> next to
+each other.
