CVE-2025-62230 4 Debian, Ibm, Redhat and 1 more 17 Debian Linux, Aix, Vios and 14 more 2026-11-05 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 2026-11-05 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-2026-11791 1 Redhat 4 389 Directory Server, Directory Server, Enterprise Linux and 1 more 2026-11-05 5 Medium
A flaw was found in 389 Directory Server. During schema reload, the attr_syntax_swap_ht() function unconditionally frees attribute syntax information nodes, bypassing the refcount-based deferred deletion used elsewhere in the attribute syntax subsystem. If an administrator triggers schema reload while concurrent LDAP query traffic is active, worker threads may access freed memory, resulting in use-after-free or double-free and a denial of service (server crash).
CVE-2026-117983 1 Mozilla 1 Firefox 2026-11-05 8.8 High
Use-after-free in the Graphics component. This vulnerability was fixed in Firefox 159, Firefox ESR 153.6, Thunderbird 159, and Thunderbird 153.6.

CVE-2024-34362 1 Envoyproxy 1 Envoy 2026-11-05 5.9 Medium
Envoy is a cloud-native, open source edge and service proxy. There is a use-after-free in `HttpConnectionManager` (HCM) with `EnvoyQuicServerStream` that can crash Envoy. An attacker can exploit this vulnerability by sending a request without `FIN`, then a `RESET_STREAM` frame, and then after receiving the response, closing the connection.
CVE-2024-32974 1 Envoyproxy 1 Envoy 2026-11-05 5.9 Medium
Envoy is a cloud-native, open source edge and service proxy. A crash was observed in `EnvoyQuicServerStream::OnInitialHeadersComplete()` with following call stack. It is a use-after-free caused by QUICHE continuing push request headers after `StopReading()` being called on the stream. As after `StopReading()`, the HCM's `ActiveStream` might have already be destroyed and any up calls from QUICHE could potentially cause use after free.
CVE-2026-107167 2 Red Hat, Redhat 3 Enterprise Linux, Enterprise Linux, Rhel Els 2026-11-05 6.2 Medium
A flaw was found in m17n-lib. A user providing specially crafted text input can trigger a heap use-after-free condition during input-method state transitions. Under specific conditions, the library frees an internal input context object but subsequently attempts to write to that freed memory. This issue can cause applications relying on the library to crash, leading to a Denial of Service (DoS), or potentially allow arbitrary code execution.
