Two more: 

CVE-2022-1240 (https://huntr.dev/bounties/e589bd97-4c74-4e79-93b5-0951a281facc):

Heap buffer overflow in libr/bin/format/mach0/mach0.c in GitHub repository radareorg/radare2 prior to 5.8.6. If address sanitizer is disabled during the compiling, the program should executes into the `r_str_ncpy` function. Therefore I think it is very likely to be exploitable. For more general description of heap buffer overflow, see [CWE](https://cwe.mitre.org/data/definitions/122.html).

CVE-2022-1244 (https://huntr.dev/bounties/8ae2c61a-2220-47a5-bfe8-fe6d41ab1f82):

heap-buffer-overflow in GitHub repository radareorg/radare2 prior to 5.6.8. This vulnerability is capable of inducing denial of service.
