This vulnerability involves an integer overflow or wraparound in Samsung Opensource Escargot that can be exploited by attackers who have write access to the bytecode-cache directory. By crafting a malicious cache file, they can cause a heap-based buffer overflow leading to denial of service. The issue affects the Escargot version identified by commit ac94df78493ee6fede286620d94f724e46b4d238. There is no vendor advisory or patch information provided, and no known exploits in the wild have been reported.

The vulnerability can cause a denial of service condition due to a heap-based buffer overflow triggered by a crafted cache file. There is no indication of confidentiality or integrity impact. Exploitation requires write access to the bytecode-cache directory, which limits the attack surface.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict write access to the bytecode-cache directory to trusted users only to reduce the risk of exploitation.
