CVE-2022-3115 is a null pointer dereference vulnerability in the Linux kernel, specifically within the malidp_crtc_reset function of the Mali Display Processor (malidp) driver, affecting versions through 5.16-rc6. This flaw stems from a missing return value check for kzalloc(), leading to a potential system crash. It carries a CVSSv3.1 score of 5.5 (Medium), indicating a local attack vector with low complexity, requiring low privileges, and resulting in high availability impact (denial of service). There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
