Microsoft Excel KB5002914 update breaks copy and paste for some users

Microsoft's September Patch Tuesday update KB5002914 breaks copy-and-paste and formula dragging in Excel 2016 through 2024; uninstalling the update restores functionality.

Users on Reddit and Microsoft Q&A report that the KB5002914 security update shipped in the September 2026 Patch Tuesday breaks copy-and-paste, autofill, and formula dragging in Excel. The problem spans Office 2016 through 2024 across MSI and Click-to-Run installations, including Office LTSC Standard 2021, with some teams blocked after widespread patching. Uninstalling KB5002914 or downgrading the Office build restores functionality, though replacing the excel.exe binary is not recommended. BleepingComputer could not reproduce the issue on Excel 2019 Version 2508 Build 19127.20302 and contacted Microsoft for comment.

The GNU C Library security advisory update for 2026-09-10

glibc advisory GLIBC-SA-2026-0016: nscd can crash from a stack overflow when an untrusted DNS server returns oversized responses.

A new GNU C Library advisory (GLIBC-SA-2026-0016) describes a stack overflow in the nscd service caused by unbounded alloca use. glibc 2.3.4 and newer may crash when a malicious DNS server returns an oversized response, resulting in degraded DNS resolution. Exploitation requires nscd to be enabled and the system to be using an untrusted DNS server. The advisory was posted to oss-security by glibc maintainer Siddhesh Poyarekar.
