Product: Wine Version: 11.5 Hardware: x86-64 OS: Linux Status: NEW Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)list.winehq.org Reporter: bernhardu(a)mailbox.org Distribution: --- Created attachment 80637 --> http://bugs.winehq.org/attachment.cgi?id=80637 wine-x64sc.exe-user-interface.png The GTK3 user interface is not properly drawn, especially menus and labels. (wine-11.5 needs the patch from bug #59561, should be included in wine-11.6.) (Emulation prints all the time these two lines, which I guess affect only the emulation part of the window and is probably another issue, maybe bug #59366: fixme:dxgi:d3d11_swapchain_Present1 Ignored present parameters 00007FE7BCC0FD80. fixme:d2d:d2d_device_context_DrawImage Unhandled image 00007FE7B4ADF768. ) -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59593] New: d3d12_desc_mark_as_modified silently drops dirty descriptors and races with flush
by WineHQ Bugzilla April 6, 2026

April 6, 2026

http://bugs.winehq.org/show_bug.cgi?id=59593 Bug ID: 59593 Summary: d3d12_desc_mark_as_modified silently drops dirty descriptors and races with flush Product: vkd3d Version: 1.19 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: vkd3d Assignee: wine-bugs(a)list.winehq.org Reporter: progamercloud2(a)gmail.com Distribution: --- Hi team, I was exploring the vkd3d descriptor management code and found what appear to be correctness issues in d3d12_desc_mark_as_modified. I wanted to bring them to your attention. Bug #1: Silent Descriptor Drops In d3d12_desc_mark_as_modified: ```c if (!vkd3d_atomic_compare_exchange_u32(&dst->next, 0, (head << 1) | 1)) return; // Descriptor dirty but not added to list ``` If the CAS fails because dst->next is already non-zero (descriptor already dirty), the function returns without adding the descriptor to the dirty list. However, the descriptor needs to be flushed. This can result in stale Vulkan descriptors and visual corruption. Bug #2: Race Between Mark and Flush During flush, d3d12_desc_flush_vk_heap_updates_locked sets dirty_list_head = UINT_MAX. Marking threads may read this value and compute: ```c vkd3d_atomic_store_u32(&dst->next, (head << 1) | 1); // head = UINT_MAX ``` This creates corrupted next pointers, leading to lost descriptors or crashes. Bug #3: Memory Leak When Bug #1 occurs, the object reference obtained via d3d12_desc_get_object_ref during the copy is never released, causing reference count leaks and gradual memory exhaustion. Hope this will be helpful... -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.

[Bug 56650] New: Report on SELinux 'execheap' Issues with wine-preloader
by WineHQ Bugzilla April 6, 2026

April 6, 2026

https://bugs.winehq.org/show_bug.cgi?id=56650 Bug ID: 56650 Summary: Report on SELinux 'execheap' Issues with wine-preloader Product: Wine Version: 9.8 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: chplee(a)gmail.com Distribution: --- This report was prepared by ChatGPT. I'm sorry that my own ability is not enough to support such a large amount of code analysis, so I have to turn to ChatGPT. I'm filing this report because a lot of people are suffering from this problem. Please refer to: https://bugzilla.redhat.com/show_bug.cgi?id=2247299 ### Report on SELinux 'execheap' Issues with `wine-preloader` #### Introduction The `wine-preloader` program is a crucial part of the Wine software, which allows Windows applications to run on Unix-like operating systems. An issue has been identified where SELinux prevents `wine-preloader` from executing code in writable memory regions, raising security alerts related to 'execheap' accesses. This report identifies potential sources of the issue in the program and provides recommendations for modifications. #### Potential Issues Identified 1. **Memory Mapping and Protection Setup**: In `wine-preloader`, memory mapping is handled with protections set that could potentially include both write and execute permissions. This is particularly evident in the function calls to `wld_mmap`, where memory protection flags are set based on the segment flags parsed from ELF headers. ```c wld_mmap((void *)(l->l_addr + c->mapstart), c->mapend - c->mapstart, c->prot, MAP_FIXED | MAP_COPY | MAP_FILE, fd, c->mapoff); ``` Here, the `c->prot` can contain combinations of `PROT_READ`, `PROT_WRITE`, and `PROT_EXEC` based on the segment's flags. 2. **Dynamic Code Generation**: Dynamic generation or modification of code could potentially occur, though not explicitly shown in the code snippets provided, it could be inferred from the overall functionality where executable code may be modified or generated on-the-fly. 3. **Modifying Memory Protection Attributes**: The use of `wld_mprotect` to change the protection attributes of memory pages could lead to states where pages are both writable and executable. ```c wld_mprotect((caddr_t) (zero & ~page_mask), page_size, c->prot|PROT_WRITE); ``` Although this snippet aims to make pages writable temporarily, if combined inappropriately with executable flags elsewhere, it could trigger SELinux policies. #### Recommendations - **Restricting Memory Permissions**: Enforce strict separations between writable and executable pages. Modify the logic that sets memory protections to ensure that no memory page is both writable and executable at the same time. This can be achieved by adjusting the ELF segment loading routines to separate code and data segments clearly. - **Use of Memory Protection Changes**: Implement a clear two-step process for handling memory that needs to be executable: - Initially, set memory to writable to modify or generate code. - Once modifications are complete, change the memory protection to executable only (removing write permissions). - **Code Audit and Testing**: Conduct a thorough audit of the places where memory permissions are set. Test under a SELinux-enforced environment to ensure that the adjustments meet security policies without hindering functionality. - **SELinux Policy Adjustments**: If `wine-preloader` inherently requires certain operations that SELinux policies restrict, consider creating custom SELinux policy modules that allow specific actions while maintaining overall security. This should be done cautiously to avoid creating unnecessary security holes. #### Conclusion Adjustments to `wine-preloader` should focus on ensuring that memory regions are either writable or executable but never both. By adhering to security best practices and possibly adjusting SELinux policies, `wine-preloader` can function effectively without triggering security violations in SELinux environments. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59247] New: Hikvision WebComponents: window flickering on WoW64
by WineHQ Bugzilla April 6, 2026

http://bugs.winehq.org/show_bug.cgi?id=59247 Bug ID: 59247 Summary: Hikvision WebComponents: window flickering on WoW64 Product: Wine Version: 11.0 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)list.winehq.org Reporter: felipecassiors(a)gmail.com Distribution: --- Created attachment 80160 --> http://bugs.winehq.org/attachment.cgi?id=80160 Screencapture showing the window flickering on Wine WoW64 It's hard to describe the issue, but here's my attempt: The whole window flickers when interacting with a browser loaded with Hikvision WebComponents. In my case, I have Wine with Firefox 31.7.0esr (https://ftp.mozilla.org/pub/firefox/releases/31.7.0esr/win32/en-US/Firefox%…) and Hikvision WebComponents installed for my old NVR. Unfortunately this is hard to reproduce by other people, since you need access to some Hikvision NVR that uses such WebComponents. I'm using Debian 13 Trixie, and when using regular winehq-staging, everything works smooth. However, when using any Wine version with WoW64, this issue happens. I have been trying ever since Wine 10.18, but decided to report it now that WoW64 is considered stable. I already tried a clean prefix, but the issue can be reproduced just fine. To install Wine WoW64 in Debian Trixie, I used Ubuntu 25.10 APT sources. However, the exact same issue happens when using the Wine builds from https://github.com/Kron4ek/Wine-Builds (and also I can confirm the issue does NOT happen when using that same build without WoW64). -- Do not reply to this email, post in Bugzilla using the above URL to reply.
