+Subject: [PATCH] awk: fix use-after-free in awk_sub()
+
+awk_sub() receives the replacement text as a pointer into awk variable
+storage. Evaluating the regular expression argument can change that
+storage through as_regex(), leaving the replacement pointer dangling
+before strlen() and the replacement loop use it.
+
+Copy the replacement string before calling as_regex() so substitution
+uses stable storage for the duration of the operation.
+
+CVE: CVE-2026-38753
