Doc Text:
A flaw was found in svxlink's audio decoders. A variable-length array on the stack is sized using an attacker-controlled encoded-frame length field received over the network. By sending a frame with an excessively large length value, a remote attacker can exhaust the stack, resulting in a denial of service.

Description OSIDB Bzimport 2026-08-11 07:31:23 UTC
A flaw was found in svxlink. The audio decoders use a variable-length array (VLA) on the stack that is sized by an attacker-controlled encoded-frame length field received over the network. A remote attacker can send a specially crafted frame with an excessively large length value, causing stack exhaustion and a denial of service. Fixed in version 26.05.1.
