CVE-2025-26599Xorg: xwayland: use of uninitialized pointer in compredirectwindow()

xserver; Red Hat Red Hat Enterprise Linux 10; Red Hat Red Hat Enterprise Linux 6 Extended Lifecycle Support - EXTENSION; Red Hat Red Hat Enterprise Linux 7 Ex… Yayım: (1 yıl önce)

Açıklama

An access to an uninitialized pointer flaw was found in X.Org and Xwayland. The function compCheckRedirect() may fail if it cannot allocate the backing pixmap. In that case, compRedirectWindow() will return a BadAlloc error without validating the window tree marked just before, which leaves the validated data partly initialized and the use of an uninitialized pointer later.

Zayıflık türü (CWE): CWE-824

Veri: CVE.org, NVD, CISA KEV, FIRST EPSS, Ubuntu. Bilgiler kaynaktaki haliyle, İngilizce yayımlanır.
