CVE-2026-53794

A flaw was found in rsync. A logic error in the --max-alloc handling allows a remote attacker to disable memory allocation sanity checks by setting --max-alloc=0. This can lead to the receiver attempting unbounded memory allocations, potentially exhausting available memory and causing a denial of...

SUSE CVE-2026-53794

rsync before 3.5.0 contains a logic error in --max-alloc handling that allows a sender or configuration setting --max-alloc=0 to disable allocation sanity checks entirely rather than enforcing a zero-byte cap. Attackers can exploit this flaw to cause the receiver to attempt unbounded memory...

Improper Validation of Specified Quantity in Input

Overview Affected versions of this package are vulnerable to Improper Validation of Specified Quantity in Input via the --max-alloc process. An attacker can exhaust system memory by setting --max-alloc=0, which disables allocation sanity checks and causes the receiver to attempt unbounded memory...

CVE-2026-53794

The CVE affects rsync prior to 3.5.0. A logic error in --max-alloc handling allows a sender or config setting --max-alloc=0 to bypass allocation sanity checks, causing unbounded memory allocations for file lists/data structures and potential memory exhaustion leading to DoS. Remediation: upgrade ...
