Prior to version 1.68.1, the nghttp2 library stops\n reading the incoming data when user facing public API\n `nghttp2_session_terminate_session` or\n `nghttp2_session_terminate_session2` is called by the application.\n They might be called internally by the library when it detects the\n situation that is subject to connection error. Due to the missing\n internal state validation, the library keeps reading the rest of the\n data after one of those APIs is called. Then receiving a malformed\n frame that causes FRAME_SIZE_ERROR causes assertion failure. nghttp2\n v1.68.1 adds missing state validation to avoid assertion failure. No\n known workarounds are available.\n\nFor more information, see:\n - https://www.cve.org/CVERecord?id=CVE-2026-27135\n - https://github.com/nghttp2/nghttp2/commit/5c7df8fa815ac1004d9ecb9d1f7595c4d37f46e1\n\nSigned-off-by: Thomas Perale \n---\n ...lidations-to-avoid-assertion-failure.patch | 105 ++++++++++++++++++\n package/nghttp2/nghttp2.mk | 3 +\n 2 files changed, 108 insertions(+)\n create mode 100644 package/nghttp2/0001-Fix-missing-iframe-state-validations-to-avoid-assertion-failure.patch","diff":"diff --git a/package/nghttp2/0001-Fix-missing-iframe-state-validations-to-avoid-assertion-failure.patch b/package/nghttp2/0001-Fix-missing-iframe-state-validations-to-avoid-assertion-failure.patch\nnew file mode 100644\nindex 0000000000..ef8b9a5a5d\n--- /dev/null\n+++ b/package/nghttp2/0001-Fix-missing-iframe-state-validations-to-avoid-assertion-failure.patch\n@@ -0,0 +1,105 @@\n+From 5c7df8fa815ac1004d9ecb9d1f7595c4d37f46e1 Mon Sep 17 00:00:00 2001\n+From: Tatsuhiro Tsujikawa \n+Date: Wed, 18 Feb 2026 18:04:30 +0900\n+Subject: [PATCH] Fix missing iframe->state validations to avoid assertion\n+ failure\n+\n+CVE: CVE-2026-27135\n+Upstream: https://github.com/nghttp2/nghttp2/commit/5c7df8fa815ac1004d9ecb9d1f7595c4d37f46e1\n+Signed-off-by: Thomas Perale \n+---\n+ lib/nghttp2_session.c | 32 ++++++++++++++++++++++++++++++++\n+ 1 file changed, 32 insertions(+)\n+\n+diff --git a/lib/nghttp2_session.c b/lib/nghttp2_session.c\n+index bcea547343..0fbcc930b9 100644\n+--- a/lib/nghttp2_session.c\n++++ b/lib/nghttp2_session.c\n+@@ -5573,6 +5573,10 @@ nghttp2_ssize nghttp2_session_mem_recv2(nghttp2_session *session,\n+ return rv;\n+ }\n+ \n++ if (iframe->state == NGHTTP2_IB_IGN_ALL) {\n++ return (nghttp2_ssize)inlen;\n++ }\n++\n+ on_begin_frame_called = 1;\n+ \n+ rv = session_process_headers_frame(session);\n+@@ -6041,6 +6045,10 @@ nghttp2_ssize nghttp2_session_mem_recv2(nghttp2_session *session,\n+ if (nghttp2_is_fatal(rv)) {\n+ return rv;\n+ }\n++\n++ if (iframe->state == NGHTTP2_IB_IGN_ALL) {\n++ return (nghttp2_ssize)inlen;\n++ }\n+ }\n+ }\n+ \n+@@ -6293,6 +6301,10 @@ nghttp2_ssize nghttp2_session_mem_recv2(nghttp2_session *session,\n+ return rv;\n+ }\n+ \n++ if (iframe->state == NGHTTP2_IB_IGN_ALL) {\n++ return (nghttp2_ssize)inlen;\n++ }\n++\n+ session_inbound_frame_reset(session);\n+ \n+ break;\n+@@ -6599,6 +6611,10 @@ nghttp2_ssize nghttp2_session_mem_recv2(nghttp2_session *session,\n+ if (nghttp2_is_fatal(rv)) {\n+ return rv;\n+ }\n++\n++ if (iframe->state == NGHTTP2_IB_IGN_ALL) {\n++ return (nghttp2_ssize)inlen;\n++ }\n+ } else {\n+ iframe->state = NGHTTP2_IB_IGN_HEADER_BLOCK;\n+ }\n+@@ -6775,6 +6791,10 @@ nghttp2_ssize nghttp2_session_mem_recv2(nghttp2_session *session,\n+ rv = session->callbacks.on_data_chunk_recv_callback(\n+ session, iframe->frame.hd.flags, iframe->frame.hd.stream_id,\n+ in - readlen, (size_t)data_readlen, session->user_data);\n++ if (iframe->state == NGHTTP2_IB_IGN_ALL) {\n++ return (nghttp2_ssize)inlen;\n++ }\n++\n+ if (rv == NGHTTP2_ERR_PAUSE) {\n+ return (nghttp2_ssize)(in - first);\n+ }\n+@@ -6861,6 +6881,10 @@ nghttp2_ssize nghttp2_session_mem_recv2(nghttp2_session *session,\n+ return rv;\n+ }\n+ \n++ if (iframe->state == NGHTTP2_IB_IGN_ALL) {\n++ return (nghttp2_ssize)inlen;\n++ }\n++\n+ if (rv != 0) {\n+ busy = 1;\n+ \n+@@ -6879,6 +6903,10 @@ nghttp2_ssize nghttp2_session_mem_recv2(nghttp2_session *session,\n+ return rv;\n+ }\n+ \n++ if (iframe->state == NGHTTP2_IB_IGN_ALL) {\n++ return (nghttp2_ssize)inlen;\n++ }\n++\n+ session_inbound_frame_reset(session);\n+ \n+ break;\n+@@ -6907,6 +6935,10 @@ nghttp2_ssize nghttp2_session_mem_recv2(nghttp2_session *session,\n+ return rv;\n+ }\n+ \n++ if (iframe->state == NGHTTP2_IB_IGN_ALL) {\n++ return (nghttp2_ssize)inlen;\n++ }\n++\n+ session_inbound_frame_reset(session);\n+ \n+ break;\ndiff --git a/package/nghttp2/nghttp2.mk b/package/nghttp2/nghttp2.mk\nindex 98f837e28e..9e051d24ed 100644\n--- a/package/nghttp2/nghttp2.mk\n+++ b/package/nghttp2/nghttp2.mk\n@@ -14,6 +14,9 @@ NGHTTP2_CPE_ID_VENDOR = nghttp2\n NGHTTP2_DEPENDENCIES = host-pkgconf\n NGHTTP2_CONF_OPTS = --enable-lib-only\n \n+# 0001-Fix-missing-iframe-state-validations-to-avoid-assertion-failure.patch\n+NGHTTP2_IGNORE_CVES += CVE-2026-27135\n+\n define NGHTTP2_INSTALL_CLEAN_HOOK\n \t# Remove fetch-ocsp-response script unused by library\n \t$(Q)$(RM) -rf $(TARGET_DIR)/usr/share/nghttp2\n","prefixes":["1/1"]}
