xorg-x11-server: xorg-x11-server-Xwayland: xorg-x11-server: stack buffer overflow in font alias resolution due to libXfont2 name length mismatch

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...

xorg-x11-server: xorg-x11-server-Xwayland: xorg-x11-server: stack buffer overflow in XKB SetMap request via mapWidths indexing

A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. XkbSetMapChecks declares a fixed-size stack buffer mapWidths256 indexed by key type index. The helper function CheckKeyTypes writes to this buffer at a client-controlled offset, allowing a stack buffer overflow. This...

CVE-2026-16554 Integer Overflow Leading to Heap Buffer Overflow in cJSON

cJSON library is vulnerable to an integer overflow in the printstringptr function in cJSON.c on 32-bit platforms. The escapecharacters counter, a 32-bit sizet, can wrap around when processing strings containing approximately 858,993,460 or more control characters, causing the output buffer to be...

CVE-2026-64384

A flaw was found in the Linux kernel's Server Message Block SMB client. This vulnerability occurs due to a double-free error when handling change notify replies. If a response attempt returns a replayable error and frees its buffer, and then SMB2notifyinit fails, the same buffer can be freed agai...

CVE-2026-64293

A flaw was found in the Linux kernel's iommufd component. This vulnerability arises from an incorrect size calculation during a bound-check in the iommufdveventqfopsread function. On 32-bit systems, this error can lead to an out-of-bounds write, allowing data to be copied past the intended...

xorg-x11-server: xorg-x11-server-Xwayland: xorg-x11-server: out-of-bounds heap write in DRI2 DRIGetBuffers/DRIGetBuffersWithFormat

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...

xorg-x11-server: xorg-x11-server-Xwayland: xorg-x11-server: stack buffer overflow in XKB key types due to unchecked shift levels

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...
