Doc Text:
A flaw was found in Capstone, a disassembly framework. An unchecked return value from vsnprintf within the SStream_concat function allows a malicious input to manipulate the internal stream index. This can lead to a stack buffer underflow or overflow, potentially enabling a local attacker to achieve information disclosure, alter data, or cause a denial of service.

Description OSIDB Bzimport 2025-12-17 22:01:51 UTC
Capstone is a disassembly framework. In versions 6.0.0-Alpha5 and prior, an unchecked vsnprintf return in SStream_concat lets a malicious cs_opt_mem.vsnprintf drive SStream’s index negative or past the end, leading to a stack buffer underflow/overflow when the next write occurs. Commit 2c7797182a1618be12017d7d41e0b6581d5d529e fixes the issue.
