Description
In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, and 8.5.* before 8.5.6, a mismatch between encoding lists in Oniguruma and mbfl leads to a NULL pointer dereference, resulting in a segmentation fault and denial of service. The vulnerability is exploitable when user-controlled input can influence the encoding passed to mb_regex_encoding().
Affected configurations
• php php (>= 8.2.0 < 8.2.31)
• php php (>= 8.3.0 < 8.3.31)
• php php (>= 8.4.0 < 8.4.21)
• php php (>= 8.5.0 < 8.5.6)
