This  \nis true on x86_64, but very much not true on i386.  \n  \nThese assumptions can cause the end condition to malfunction, leading  \nto a 'short' clone. Guess what happens when the user mapping has a  \nshort copy of the entry text?  \n  \nUse the correct increment form for addr to avoid alignment  \nassumptions. \nSeverity: 0.0 | NA \nVisit the link for more details, such as CVSS details, affected products, timeline, and more...\",\n  \"Detection Date\": \"04 Sep 2024\",\n  \"Type\": \"Vulnerability\"\n}\n\ud83d\udd39 t.me/cvedetector \ud83d\udd39", "creation_timestamp": "2024-09-04T21:56:26.000000Z"}
