krb5: MIT Kerberos 5 (krb5): Denial of Service via integer underflow and out-of-bounds read

A flaw was found in MIT Kerberos 5 krb5. An unauthenticated remote attacker can exploit an integer underflow and an out-of-bounds read vulnerability by calling gssacceptseccontext on a system with a NegoEx mechanism registered. This can lead to the process terminating, resulting in a Denial of...

CVE-2026-43492

A flaw was found in the Linux kernel. A local user could trigger an integer underflow in the mpireadrawfromsgl function within the lib/crypto: mpi component. This occurs when invoking a KEYCTLPKEYENCRYPT system call with a larger output length than input length and providing a zero-filled input...

xorg: xwayland: X.Org X server: Denial of Service via integer underflow in XKB compatibility map handling

A flaw was found in the X.Org X server. This integer underflow vulnerability, specifically in the XKB compatibility map handling, allows an attacker with local or remote X11 server access to trigger a buffer read overrun. This can lead to memory-safety violations and potentially a denial of servi...
