CVE-2022-49080 is a memory leak vulnerability in the Linux kernel's memory management subsystem, specifically within the mpol_new allocation process during shared memory policy replacement. This flaw can lead to resource exhaustion (denial of service) due to uninitialized reference counts preventing proper deallocation of unused memory policy objects. Rated Medium severity (CVSS 5.5), it requires local access and low privileges to exploit, with low attack complexity. There is no evidence of active exploitation, publicly available exploit code, or significant community discussion surrounding this vulnerability.
