# CVE-2026-10536: HTTP/2 stream-dependency tree UAF

## TL;DR
HTTP/2 stream-dependency tree UAF

## Key Points
- cve / CVE-2026-10536 / CURL-CVE-2026-10536 / severity:Low / https://github.com/curl/curl / GIT

## Details
**Severity:** Low
**Advisory:** CURL-CVE-2026-10536 (CVE-2026-10536)

**Affected (your watchlist):**
- `GIT:https://github.com/curl/curl` curl-8_9_1 → no fixed version listed [mac]

**Details:**
A use-after-free vulnerability exists in libcurl when an application
configures an HTTP/2 stream-dependency tree via `CURLOPT_STREAM_DEPENDS` or
`CURLOPT_STREAM_DEPENDS_E`, subsequently invokes `curl_easy_reset()`, and
finally terminates the handle with `curl_easy_cleanup()`. During this final
cleanup phase, libcurl attempts to access and modify an internal structure
that was already freed during the reset operation.
