CVE-2026-54502

Oj Optimized JSON is a JSON parser and Object marshaller packaged as a Ruby gem. In versions prior to 3.17.2, Oj.dump is vulnerable to a stack-based buffer overflow when a large :indent value is provided by the developer. fillindent in dump.h calls memsetindentstr, ' ', sizetopts-indent without...

CVE-2026-54592

A flaw was found in Oj, a Ruby gem for JSON parsing. A remote attacker can exploit this vulnerability by providing a deeply nested JSON document. This can lead to a stack buffer overflow in the Oj::Doceachchild function, causing the process to abort and resulting in a denial of service DoS for th...

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...

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 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...

Unbounded mutual recursion in the TOML parser of github.com/pelletier/go-toml/v2. "unstable.Parser.parseVal" dispatches nested arrays and inline tables to "parseValArray" and "parseInlineTable", which loop back into "parseVal" with no depth limit. A TOML document with deeply nested arrays or inli...
