Details

An out-of-bounds read vulnerability was discovered in the PCRE2 library in the compilexclassmatchingpath() function of the pcre2jitcompile.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.
