CVE-2026-26983 1 Imagemagick 1 Imagemagick 2026-02-28 5.3 Medium
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, the MSL interpreter crashes when processing a invalid `<map>` element that causes it to use an image after it has been freed. Versions 7.1.2-15 and 6.9.13-40 contain a patch.
CVE-2026-25983 1 Imagemagick 1 Imagemagick 2026-02-28 5.3 Medium
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, a crafted MSL script triggers a heap-use-after-free. The operation element handler replaces and frees the image while the parser continues reading from it, leading to a UAF in ReadBlobString during further parsing. Versions 7.1.2-15 and 6.9.13-40 contain a patch.
CVE-2026-1979 1 Mruby 1 Mruby 2026-02-28 5.3 Medium
A flaw has been found in mruby up to 3.4.0. This affects the function mrb_vm_exec of the file src/vm.c of the component JMPNOT-to-JMPIF Optimization. Executing a manipulation can lead to use after free. The attack needs to be launched locally. The exploit has been published and may be used. This patch is called e50f15c1c6e131fa7934355eb02b8173b13df415. It is advisable to implement a patch to correct this issue.
CVE-2026-2408 1 Tanium 2 Cloud Workloads, Service Cloudworkloads 2026-02-27 4.7 Medium
Tanium addressed a use-after-free vulnerability in the Cloud Workloads Enforce client extension.
CVE-2026-21237 1 Microsoft 19 Windows 10 21h2, Windows 10 21h2, Windows 10 22h2 and 16 more 2026-02-27 7 High

CVE-2026-21241 1 Microsoft 15 Windows 11 22h3, Windows 11 23h2, Windows 11 23h2 and 12 more 2026-02-27 7 High
Use after free in Windows Ancillary Function Driver for WinSock allows an authorized attacker to elevate privileges locally.
CVE-2026-21251 1 Microsoft 10 Windows Server 2016, Windows Server 2016 (server Core Installation), Windows Server 2019 and 7 more 2026-02-27 7.8 High
Use after free in Windows Cluster Client Failover allows an authorized attacker to elevate privileges locally.
CVE-2026-21253 1 Microsoft 30 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 27 more 2026-02-27 7 High
Use after free in Mailslot File System allows an authorized attacker to elevate privileges locally.
CVE-2026-21235 1 Microsoft 21 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 18 more 2026-02-27 7.3 High
Use after free in Microsoft Graphics Component allows an authorized attacker to elevate privileges locally.
CVE-2026-21242 1 Microsoft 19 Windows 10 21h2, Windows 10 21h2, Windows 10 22h2 and 16 more 2026-02-27 7 High
Use after free in Windows Subsystem for Linux allows an authorized attacker to elevate privileges locally.
CVE-2026-26986 1 Freerdp 1 Freerdp 2026-02-27 7.5 High
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, `rail_window_free` dereferences a freed `xfAppWindow` pointer during `HashTable_Free` cleanup because `xf_rail_window_common` calls `free(appWindow)` on title allocation failure without first removing the entry from the `railWindows` hash table, leaving a dangling pointer that is freed again on disconnect. Version 3.23.0 fixes the vulnerability.
CVE-2026-27950 1 Freerdp 1 Freerdp 2026-02-27 7.5 High
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, the fix for the heap-use-after-free described in CVE-2026-24680 is incomplete. While the vulnerable execution flow referenced in the advisory exists in the SDL2 implementation, the fix appears to have been applied only to the SDL3 code path. In the SDL2 implementation, the pointer is not nulled after free. This creates a situation where the advisory suggests the vulnerability is fully resolved, while builds or environments still using SDL2 may retain the vulnerable logic. A complete fix is available in version 3.23.0.
CVE-2025-15570 1 Ckolivas 1 Lrzip 2026-02-27 5.3 Medium
A vulnerability was found in ckolivas lrzip up to 0.651. This impacts the function lzma_decompress_buf of the file stream.c. Performing a manipulation results in use after free. Attacking locally is a requirement. The exploit has been made public and could be used. The project was informed of the problem early through an issue report but has not responded yet.
CVE-2026-25997 1 Freerdp 1 Freerdp 2026-02-27 9.8 Critical
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, `xf_clipboard_format_equal` reads freed `lastSentFormats` memory because `xf_clipboard_formats_free` (called from the cliprdr channel thread during auto-reconnect) frees the array while the X11 event thread concurrently iterates it in `xf_clipboard_changed`, triggering a heap use after free. Version 3.23.0 fixes the issue.
CVE-2026-25955 1 Freerdp 1 Freerdp 2026-02-27 9.8 Critical
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, `xf_AppUpdateWindowFromSurface` reuses a cached `XImage` whose `data` pointer references a freed RDPGFX surface buffer, because `gdi_DeleteSurface` frees `surface->data` without invalidating the `appWindow->image` that aliases it. Version 3.23.0 fixes the issue.
CVE-2026-25954 1 Freerdp 1 Freerdp 2026-02-27 7.5 High
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, `xf_rail_server_local_move_size` dereferences a freed `xfAppWindow` pointer because `xf_rail_get_window` returns an unprotected pointer from the `railWindows` hash table, and the main thread can concurrently delete the window (via a window delete order) while the RAIL channel thread is still using the pointer. Version 3.23.0 fixes the issue.
