Description Oleg Sushchenko 2026-11-03 14:54:48 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

libosmocore through 1.14.1 contains an out-of-bounds read in the CBSP WRITE-REPLACE decoder in src/gsm/cbsp.c. This allows a remote attacker to cause a denial of service.
