A vulnerability was found in Sony PS4 and PS5 (Game Console) (affected version unknown). It has been classified as critical. This affects the function UVFAT_readupcasetable of the component exFAT Handler. The manipulation of the argument dataLength with an unknown input leads to a heap-based overflow vulnerability. CWE is classifying the issue as CWE-122. A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). This is going to have an impact on confidentiality, integrity, and availability.

The weakness was shared 09/28/2022 by Andy Nguyen as #1340942. It is possible to read the advisory at This vulnerability is uniquely identified as CVE-2022-3349. Technical details and a exploit are known.

It is declared as proof-of-concept.

Upgrading eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability.
