CVE-2026-58010 [HIGH] CWE-126 CVE-2026-58010: A flaw was found in GLib. An off-by-one error can occur in the gvs_tuple_is_normal function in the g A flaw was found in GLib. An off-by-one error can occur in the gvs_tuple_is_normal function in the glib/gvariant-serialiser.c file when doing an alignment padding check because the bounds check uses > instead of >=, causing an out-of-bounds read of only 1 byte. This issue can cause a minor information disclosure of 1 byte and a denial of service when

CVE-2026-58012 [HIGH] CWE-126 CVE-2026-58012: A flaw was found in GLib. A buffer over-read can occur in the g_regex_replace function when used wit A flaw was found in GLib. A buffer over-read can occur in the g_regex_replace function when used with the `G_REGEX_RAW` compile flag and case-change replacement escapes because the string_append function processes matched substrings using UTF-8 functions that assume valid UTF-8 input, even when the string is treated as raw bytes. This vulnerability ca

CVE-2020-11868 [HIGH] CWE-346 CVE-2020-11868: ntpd in ntp before 4.2.8p14 and 4.3.x before 4.3.100 allows an off-path attacker to block unauthenti ntpd in ntp before 4.2.8p14 and 4.3.x before 4.3.100 allows an off-path attacker to block unauthenticated synchronization via a server mode packet with a spoofed source IP address, because transmissions are rescheduled even when a packet lacks a valid origin timestamp.

CVE-2023-3138 [HIGH] CWE-119 CVE-2023-3138: A vulnerability was found in libX11. The security flaw occurs because the functions in src/InitExt.c A vulnerability was found in libX11. The security flaw occurs because the functions in src/InitExt.c in libX11 do not check that the values provided for the Request, Event, or Error IDs are within the bounds of the arrays that those functions write to, using those IDs as array indexes. They trust that they were called with values provided by an Xserver

CVE-2023-3354 [HIGH] CWE-476 CVE-2023-3354: A flaw was found in the QEMU built-in VNC server. When a client connects to the VNC server, QEMU che A flaw was found in the QEMU built-in VNC server. When a client connects to the VNC server, QEMU checks whether the current number of connections crosses a certain threshold and if so, cleans up the previous connection. If the previous connection happens to be in the handshake phase and fails, QEMU cleans up the connection again, resulting in a NULL poi

CVE-2025-26600 [HIGH] CWE-416 CVE-2025-26600: A use-after-free flaw was found in X.Org and Xwayland. When a device is removed while still frozen, A use-after-free flaw was found in X.Org and Xwayland. When a device is removed while still frozen, the events queued for that device remain while the device is freed. Replaying the events will cause a use-after-free.

CVE-2025-26594 [HIGH] CWE-416 CVE-2025-26594: A use-after-free flaw was found in X.Org and Xwayland. The root cursor is referenced in the X server A use-after-free flaw was found in X.Org and Xwayland. The root cursor is referenced in the X server as a global variable. If a client frees the root cursor, the internal reference points to freed memory and causes a use-after-free.
