[PATCH v2 0/1] MR9339: winhttp/tests: Avoid buffer-overflow in WinHttpCreateUrl_test (ASan).
by Bernhard Übelacker Nov. 3, 2025

Nov. 3, 2025

The test sets in fill_url_components the dwPasswordLength to 8, therefore the memcpy copies 8 wide characters. But before this patch variable empty allocates just one wide character. [ASan report details](https://gitlab.winehq.org/bernhardu/wine/-/blob/asan-pe_2025-10-18… -- v2: winhttp/tests: Fix setting string lengths in WinHttpCreateUrl_test (ASan). https://gitlab.winehq.org/wine/wine/-/merge_requests/9339

[PATCH v3 0/5] MR9271: Implement group affinity support in CreateRemoteThreadEx.
by eric pouech (＠epo) Nov. 3, 2025

Nov. 3, 2025

This MR implements group affinity support in attributes list passed to CreateRemoteThreadEx(). (up to the current Wine limit of 64 logical cores). It also adds a couple of missing APIs definitions related to group affinity support. Notes: - duplicating for the Nth time struct \_PROC\_THREAD\_ATTRIBUTE\_LIST definition isn't very nice... perhaps we should define it somewhere? - it's very likely that CreateRemoteThreadEx() should call into NtCreateThreadEx() (instead of the Rtl counter part), but I opted for the simpler approach to set thread affinity after thread creation (this could be changed if needed). -- v3: kernelbase: Support group affinity attributes. kernel32/tests: Test thread creation with group affinity attributes. include: Add missing process group related definitions. kernelbase: Support affinity group in process/thread attributes list. kernel32: Test adding group affinity to proc/thread attributes list. https://gitlab.winehq.org/wine/wine/-/merge_requests/9271
