Summary
In the Linux kernel, the following vulnerability has been resolved:
f2fs: quota: fix loop condition at f2fs_quota_sync()
cnt should be passed to sb_has_quota_active() instead of type to check
active quota properly.
Moreover, when the type is -1, the compiler with enough inline knowledge
can discard sb_has_quota_active() check altogether, causing a NULL pointer
dereference at the following inode_lock(dqopt->files[cnt]):

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.
