CVE-2026-10649

Pacemaker: pacemaker: denial of service via integer overflow in remote message decompression

A flaw was found in Pacemaker. An unauthenticated remote attacker can exploit an integer overflow vulnerability in the remote message decompression process. By sending a specially crafted compressed remote message before authentication, an attacker can cause memory corruption, leading to a denial of service (DoS) in the CIB remote listener. This can result in the affected service crashing.

Xorg: xwayland: use-after-free in syncinittrigger()

A use-after-free flaw was found in X.Org and Xwayland. When changing an alarm, the values of the change mask are evaluated one after the other, changing the trigger values as requested, and eventually, SyncInitTrigger() is called. If one of the changes triggers an error, the function will return early, not adding the new sync object, possibly causing a use-after-free when the alarm eventually triggers.

Xorg: xwayland: out-of-bounds write in createpointerbarrierclient()

An out-of-bounds write flaw was found in X.Org and Xwayland. The function GetBarrierDevice() searches for the pointer device based on its device ID and returns the matching value, or supposedly NULL, if no match was found. However, the code will return the last element of the list if no matching device ID is found, which can lead to out-of-bounds memory access.

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.

If the same function is later called with a non-zero value of groups, this will cause a buffer overflow because the key actions are of the wrong size.

CVE-2025-3931

Yggdrasil: local privilege escalation in yggdrasil

A flaw was found in Yggdrasil, which acts as a system broker, allowing the processes to communicate to other children's "worker" processes through the DBus component. Yggdrasil creates a DBus method to dispatch messages to workers. However, it misses authentication and authorization checks, allowing every system user to call it. One available Yggdrasil worker acts as a package manager with capabilities to create and enable new repositories and install or remove packages. This flaw allows an attacker with access to the system to leverage the lack of authentication on the dispatch message to force the Yggdrasil worker to install arbitrary RPM packages. This issue results in local privilege escalation, enabling the attacker to access and modify sensitive system data.
