Description SMASH SMASH 2024-01-15 10:21:35 UTC 
A Null pointer de-reference problem was found in ida_free in lib/idr.c file when it calls the xas_load function and returns a null value, assigning NULL to the bitmap variable.

Therefore, `if (xa_is_value(bitmap))` will fail and jump to the `else` branch. However, in the else branch, the statement `if (!test_bit(bit, bitmap->bitmap))` references the member of bitmap, which triggers a null pointer dereference vulnerability.
