CVE-2022-49080 (GCVE-0-2022-49080)

Vulnerability from cvelistv5 – Published: 2025-02-26 01:54 – Updated: 2026-05-11 18:52

Title

mm/mempolicy: fix mpol_new leak in shared_policy_replace

Summary

In the Linux kernel, the following vulnerability has been resolved: mm/mempolicy: fix mpol_new leak in shared_policy_replace If mpol_new is allocated but not used in restart loop, mpol_new will be freed via mpol_put before returning to the caller. But refcnt is not initialized yet, so mpol_put could not do the right things and might leak the unused mpol_new. This would happen if mempolicy was updated on the shared shmem file while the sp->lock has been dropped during the memory allocation. This issue could be triggered easily with the below code snippet if there are many processes doing the below work at the same time: shmid = shmget((key_t)5566, 1024 * PAGE_SIZE, 0666|IPC_CREAT); shm = shmat(shmid, 0, 0); loop many times { mbind(shm, 1024 * PAGE_SIZE, MPOL_LOCAL, mask, maxnode, 0); mbind(shm + 128 * PAGE_SIZE, 128 * PAGE_SIZE, MPOL_DEFAULT, mask, maxnode, 0); }

But refcnt is not\ninitialized yet, so mpol_put could not do the right things and might\nleak the unused mpol_new.  This would happen if mempolicy was updated on\nthe shared shmem file while the sp-\u003elock has been dropped during the\nmemory allocation.\n\nThis issue could be triggered easily with the below code snippet if\nthere are many processes doing the below work at the same time:\n\n  shmid = shmget((key_t)5566, 1024 * PAGE_SIZE, 0666|IPC_CREAT);\n  shm = shmat(shmid, 0, 0);\n  loop many times {\n    mbind(shm, 1024 * PAGE_SIZE, MPOL_LOCAL, mask, maxnode, 0);\n    mbind(shm + 128 * PAGE_SIZE, 128 * PAGE_SIZE, MPOL_DEFAULT, mask,\n          maxnode, 0);\n  }"

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
