Descriptions
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]): [ 2.796010] Unable to handle kernel NULL pointer dereference at virtual address 00000000000000a0
