CVE(s):
CVE-2025-62230
A flaw was discovered in the X.Org X servers 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-2025-62231
A flaw was identified in the X.Org X servers 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-2024-9632
A flaw was found in the X.org server. Due to improperly tracked allocation size in _XkbSetCompatMap, a
local attacker may be able to trigger a buffer overflow condition via a specially crafted payload, leading
to denial of service or local privilege escalation in distributions where the X.org server is run with
root privileges.
CVE-2025-62229
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.
Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.
