rsync: Rsync: Use-after-free vulnerability in extended attribute handling

Published Apr 16, 2026 CVSS 3.1 · 7.4 High EPSS < 1% KEV · Not listed
Description
In rsync 3.0.1 through 3.4.1, receive_xattr relies on an untrusted length value during a qsort call, leading to a receiver use-after-free. The victim must run rsync with -X (aka --xattrs). On Linux, many (but not all) common configurations are vulnerable. Non-Linux platforms are more widely vulnerable.
