CVE-2021-29477 is an integer overflow vulnerability in Redis versions 6.0 and newer, affecting products such as fedoraproject and redislabs Redis. This high-severity flaw (CVSS 8.8) allows an authenticated attacker to corrupt the heap via the STRALGO LCS command, potentially leading to remote code execution. While there is no evidence of active exploitation or publicly available exploit code, patching to versions 6.2.3 or 6.0.13, or restricting the STRALGO LCS command via ACL, is recommended. Community discussion and media coverage for this CVE are minimal.
