A flaw was found in WebKitGTK. This vulnerability allows remote, user-assisted information disclosure that can reveal any file the user is permitted to read via abusing the file drag-and-drop mechanism where WebKitGTK does not verify that drag operations originate from outside the browser.
CVE-2025-62230 1 Redhat 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more 2026-04-20 7.3 High
A flaw was discovered in the X.Org X server’s X Keyboard (Xkb) extension when handling client resource cleanup. The software frees certain data structures without properly detaching related resources, leading to a use-after-free condition. This can cause memory corruption or a crash when affected clients disconnect.
CVE-2025-62229 1 Redhat 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more 2026-04-20 7.3 High
A flaw was found in the X.Org X server and Xwayland when processing X11 Present extension notifications. Improper error handling during notification creation can leave dangling pointers that lead to a use-after-free condition. This can cause memory corruption or a crash, potentially allowing an attacker to execute arbitrary code or cause a denial of service.
CVE-2025-13502 1 Redhat 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more 2026-04-20 7.5 High
A flaw was found in WebKitGTK and WPE WebKit. This vulnerability allows an out-of-bounds read and integer underflow, leading to a UIProcess crash (DoS) via a crafted payload to the GLib remote inspector server.
CVE-2025-62231 1 Redhat 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more 2026-04-20 7.3 High
A flaw was identified in the X.Org X server’s X Keyboard (Xkb) extension where improper bounds checking in the XkbSetCompatMap() function can cause an unsigned short overflow. If an attacker sends specially crafted input data, the value calculation may overflow, leading to memory corruption or a crash.
CVE-2025-59089 1 Redhat 8 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 5 more 2026-04-20 5.9 Medium
If an attacker causes kdcproxy to connect to an attacker-controlled KDC server (e.g. through server-side request forgery), they can exploit the fact that kdcproxy does not enforce bounds on TCP response length to conduct a denial-of-service attack. While receiving the KDC's response, kdcproxy copies the entire buffered stream into a new buffer on each recv() call, even when the transfer is incomplete, causing excessive memory allocation and CPU usage. Additionally, kdcproxy accepts incoming response chunks as long as the received data length is not exactly equal to the length indicated in the response header, even when individual chunks or the total buffer exceed the maximum length of a Kerberos message. This allows an attacker to send unbounded data until the connection timeout is reached (approximately 12 seconds), exhausting server memory or CPU resources. Multiple concurrent requests can cause accept queue overflow, denying service to legitimate clients.
