An out-of-bounds read vulnerability was discovered in the PCRE2 library in
the compile_xclass_matchingpath() function of the pcre2_jit_compile.c file.
This involves a unicode property matching issue in JIT-compiled regular
expressions. The issue occurs because the character was not fully read in
case-less matching within JIT.
