CVE-2026-88842 (GCVE-0-2026-88842)

Vulnerability from cvelistv5 – Published: 2026-10-14 10:02 – Updated: 2026-10-15 19:33

Title

Busybox: busybox: dpkg stale field_start pointer causes out-of-bounds read and status file corruption

Summary

A flaw was found in BusyBox dpkg. The write_status_file() function does not reset a field cursor between package stanzas. When two packages are removed in a single invocation and the first stanza is larger than the second, the second package stanza can be dropped from the status file, causing limited data corruption.

Severity

3.3 (Low)
