Blender 4.5.15 與 5.2.3 之前版本發現堆疊越界漏洞 CVE-2026-119722
CVE-2026-119722 - Blender before 4.5.15 and 5.x before 5.2.3 Heap Out-of-Bounds Access via read_struct()
Blender 4.5.15 與 5.2.3 之前版本存在堆疊越界漏洞，可能導致程式崩潰或執行惡意程式碼。
Blender 4.5.15 及 5.2.3 以上版本已修復堆疊越界漏洞，使用者應盡速升級以避免程式崩潰或執行惡意程式碼。
Blender before 4.5.15 and 5.x before 5.2.3 contains a heap out-of-bounds access vulnerability in read_struct() that skips size validation when a .blend file's SDNA struct layout compares equal. Attackers can supply a crafted .blend file with short blocks so field reads, writes, and pointer dereferences overrun heap memory, causing crashes or code execution.
