Patch availableOut-of-bounds write in .NET Framework allows an unauthorized attacker to execute code over a network.
Out-of-bounds write in .NET Framework allows an unauthorized attacker to execute code over a network.
A bounds error lets data be written beyond the intended memory region, potentially corrupting control data.
An attacker operating through a network path may attempt exploitation without authentication after a user interaction. If successful, the issue may execute code or commands in the affected security context.

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
CWE-787: Out-of-bounds Write. The product writes data past the end, or before the beginning, of the intended buffer.
