In PHP 8.0.X before 8.0.28, 8.1.X before 8.1.16 and 8.2.X before 8.2.3,
core path resolution function allocate buffer one byte too small. When
resolving paths with lengths close to system MAXPATHLEN setting, this may
lead to the byte after the allocated buffer being overwritten with NUL
value, which might lead to unauthorized data access or modification.
