+Subject: [PATCH] Charset: fixed another rare buffer overread in
+ recode_from_utf8()
+
+With prerequisites similar to 696a7f1b9, it was possible to gain 1-byte
+overread on invalid UTF-8 sequences.  The reason is ngx_utf8_decode()
+stops advancing the pointer position on the first encountered invalid
+byte.  The fix is to adjust the advanced pointer up to the whole saved
+sequence in this case.  Note that this may result in different output
+compared to complete invalid UTF-8 sequences, which we can disregard
+at this point.
+
+Reported by Han Yan of Xiaomi and p4p3r of CYBERONE.

+CVE: CVE-2026-48142
