CVE-2026-50259

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-2026-50258

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...

CVE-2026-50258

The CVE affects the X.Org X server and Xwayland. A stack-based buffer overflow arises from unchecked key-type shift levels in XkbKeyTypes: multiple stack buffers sized XkbMaxShiftLevel * XkbNumKbdGroups are not clamped by CheckKeyTypes(), allowing a client to set excessive shift levels and trigge...

CVE-2026-48526

A flaw was found in PyJWT, a Python library for JSON Web Token JWT implementation. When decoding JWTs, the library fails to validate the use of JSON Web Keys JWK in the HMAC algorithm while also supporting asymmetric algorithms. This allows a remote attacker to use the issuer's public key as the...

[SECURITY] Fedora 44 Update: perl-Crypt-Argon2-0.031-1.fc44

This module implements the Argon2 key derivation function, which is suitable to convert any password into a cryptographic key. This is most often used to for secure storage of passwords but can also be used to derive a encryption key from a password. It offers variable time and memory costs as we...
