Vulnerability from github – Published: 2025-04-14 21:32 – Updated: 2025-04-14 21:32

Details

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]):
