asterisk: Asterisk is an open source private branch exchange and telephony toolkit
CVE-2026-57197 is fixed in asterisk on 1 platform by DEBIAN-CVE-2026-57197 (version 1:22.10.1+dfsg+~cs6.17.60671434-1), released October 28, 2026. It is not reported as exploited. Patch Radar priority: Routine.
Asterisk is an open source private branch exchange and telephony toolkit. Prior to Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 20.7-cert11, 22.8-cert3, an unbounded `memcpy` of `OGG/Speex` packet data in `format_ogg_speex` can cause a heap buffer overflow and crash Asterisk when reading a file containing corrupted Speex audio. The attacker must create the file and make it available to Asterisk either through sufficiently elevated privileges or by convincing an Asterisk administrator to make it available. Asterisk must also be configured to play that file. This issue is fixed in Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 20.7-cert11, 22.8-cert3.
