Yayın: 5 Haziran 2026 15:16 · Güncelleme: 6 Kasım 2026 10:18

Açıklama (NVD)

An out-of-bounds read flaw was found in the X.Org X server and Xwayland in __glXDisp_ChangeDrawableAttributes(). A wrong size validation check can read a client-controlled number of bytes, exceeding the request buffer, leading to information disclosure. A write path also exists but requires byte-swapped clients which is disabled by default.
