| php | ≥ 8.2.0, < 8.2.31≥ 8.3.0, < 8.3.31≥ 8.4.0, < 8.4.21≥ 8.5.0, < 8.5.6 | 8.2.318.3.318.4.218.5.6 |
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().
