CVE-2026-6040 1 The Document Foundation 1 Libreoffice 2026-06-18 7.3 High
A heap use-after-free existed when importing the blank-width characters of an ODF number format. A position value read from the document was not checked against the length of the format-code string, so a malformed number format could be processed against memory outside that string. In fixed versions the position is bounds-checked before use.
CVE-2026-8357 1 The Document Foundation 1 Libreoffice 2026-06-18 7.8 High
LibreOffice Calc compiles cell formulas when opening a spreadsheet. A heap buffer overflow existed when compiling a very long formula made up of many opening tokens. The array that tracks nesting depth was allocated one element too small for that worst case, so such a formula wrote one element past its end. In fixed versions the array is sized to hold the largest possible nesting.
CVE-2026-50263 2 Redhat, X.org 3 Enterprise Linux, X Server, Xwayland 2026-06-18 5.5 Medium
A use-after-free flaw was found in the X.Org X server and Xwayland in CreateSaverWindow(). A client can trigger a use-after-free read after changing window attributes and forcing the screen saver, leading to information disclosure.
CVE-2026-50262 2 Redhat, X.org 4 Enterprise Linux, X Server, Xorg-server and 1 more 2026-06-18 5.5 Medium
An out-of-bounds read flaw was found in the X.Org X server and Xwayland in __glXDisp_ChangeDrawableAttributes(). A wrong size validation check can read a client-controlled number of bytes, exceeding the request buffer, leading to information disclosure. A write path also exists but requires byte-swapped clients which is disabled by default.
CVE-2026-50261 2 Redhat, X.org 4 Enterprise Linux, X Server, Xorg-server and 1 more 2026-06-18 7.8 High
A use-after-free flaw was found in the X.Org X server and Xwayland in SyncChangeCounter(). A client that sets up multiple SyncCounters can trigger a use-after-free when destroying those counters via a second client connection while changing those counters. This may be used to crash the server, or for privilege escalation if the X server runs as root.
CVE-2026-50260 2 Redhat, X.org 4 Enterprise Linux, X Server, Xorg-server and 1 more 2026-06-18 7.8 High
A use-after-free flaw was found in the X.Org X server and Xwayland in FreeCounter(). A client that sets up multiple SyncCounters and awaits on those triggers can trigger a use-after-free when destroying those counters via a second client connection. This may be used to crash the server, or for privilege escalation if the X server runs as root.
CVE-2026-50259 3 Redhat, X.org, Xorg 5 Enterprise Linux, X Server, Xorg-server and 2 more 2026-06-18 7.8 High
A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. _XkbSetMapChecks() declares a fixed-size stack buffer mapWidths[256] indexed by key type index. The helper function CheckKeyTypes() writes to this buffer at a client-controlled offset, allowing a stack buffer overflow. This may be used to crash the server, or for privilege escalation if the X server runs as root.
CVE-2026-50258 2 Redhat, X.org 3 Enterprise Linux, X Server, Xwayland 2026-06-18 7.8 High
A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. The X server has multiple stack buffers sized XkbMaxShiftLevel * XkbNumKbdGroups but CheckKeyTypes() does not verify or clamp non-canonical key types to XkbMaxShiftLevel. A client can change key types to excessive shift levels and trigger stack overflows. This is caused by an incomplete fix of CVE-2025-26597. This may be used to crash the server, or for privilege escalation if the X server runs as root.
CVE-2026-50257 2 Redhat, X.org 4 Enterprise Linux, X Server, Xorg-server and 1 more 2026-06-18 7.8 High
A use-after-free flaw was found in the X.Org X server and Xwayland in miSyncDestroyFence(). A client that sets up multiple fence triggers can trigger a use-after-free function pointer call. An attacker would connect to the X server to set up a fence and await that fence, then a second X connection destroys the fence, causing the use-after-free. This may be used to crash the server, or for privilege escalation if the X server runs as root.
CVE-2026-50256 2 Redhat, X.org 4 Enterprise Linux, X Server, Xorg-server and 1 more 2026-06-18 7.8 High
A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. A mismatch between the X server and the libXfont2 library's maximum font name length can cause a stack buffer overflow during font alias resolution. The server allocates a 256 byte stack buffer but libXfont2's alias target name length is 1024 bytes. A font alias name between 257 and 1023 bytes causes the X server to copy that name into the undersized stack buffer without further checks. This may be used to crash the server, or for privilege escalation if the X server runs as root.
CVE-2026-50264 2 Redhat, X.org 4 Enterprise Linux, X Server, Xorg-server and 1 more 2026-06-18 7.8 High
An out-of-bounds write flaw was found in the X.Org X server and Xwayland in DRIGetBuffers/DRIGetBuffersWithFormat. A client that requests multiple DRI2BufferBackLeft attachments and one DRI2BufferFrontLeft can trigger an out-of-bounds heap write. This may be used to crash the server, or for privilege escalation if the X server runs as root.
