CVE-2022-36227 is a critical NULL pointer dereference vulnerability in libarchive versions prior to 3.6.2, affecting products like Debian, Fedora, and Splunk. With a CVSS score of 9.8, it presents a high risk due to its network-based attack vector, low attack complexity, and potential for high impact on confidentiality, integrity, and availability. While the discoverer suggested potential for code execution, this is disputed by third parties. There is currently no evidence of active exploitation, public exploit code, or significant community discussion surrounding this vulnerability.

Aug 30, 2023In libarchive before 3.6.2 the software does not check for an error after calling calloc function that can return with a NULL pointer if the function fails which leads to a resultant NULL pointer dereference. NOTE: the discoverer cites this CWE-476 remark but third parties dispute the code-execution impact: "In rare circumstances when NULL is equivalent to the 0x0 memory address and privileged code can access it then writing or reading memory is possible which may lead to code execution."
