Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: quota: Fix race of dquot_scan_active()
with quota deactivation dquot_scan_active() can race with quota deactivation in quota_release_workfn()
like: CPU0 (quota_release_workfn) CPU1 (dquot_scan_active) ==============================
============================== spin_lock(&dq_list_lock); list_replace_init( &releasing_dquots, &rls_head);
/* dquot X on rls_head, dq_count == 0, DQ_ACTIVE_B still set */ spin_unlock(&dq_list_lock);
synchronize_srcu(&dquot_srcu); spin_lock(&dq_list_lock); list_for_each_entry(dquot, &inuse_list, dq_inuse)
{ /* finds dquot X */ dquot_active(X) -> true atomic_inc(&X->dq_count); } spin_unlock(&dq_list_lock);
spin_lock(&dq_list_lock); dquot = list_first_entry(&rls_head);
WARN_ON_ONCE(atomic_read(&dquot->dq_count)); The problem is not only a cosmetic one as under memory
pressure the caller of dquot_scan_active() can end up working on freed dquot. Fix the problem by making
sure the dquot is removed from releasing list when we acquire a reference to it. (CVE-2026-53050)
