- Summary
- f2fs: quota: fix loop condition at f2fs_quota_sync()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
f2fs: quota: fix loop condition at f2fsquotasync()
cnt should be passed to sbhasquota_active() instead of type to check active quota properly.
Moreover, when the type is -1, the compiler with enough inline knowledge can discard sbhasquotaactive() check altogether, causing a NULL pointer dereference at the following inodelock(dqopt->files[cnt]):
