The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

In the Linux kernel, the following vulnerability has been resolved:
gfs2: fix quota init duplicate scan
gfs2_quota_init() checks for duplicate quota_change IDs while holding qd_lock and the quota hash bucket bitlock. That path used gfs2_qd_search_bucket(), which takes a lockref reference via lockref_get_not_dead().
On PREEMPT_RT this may sleep, which is not allowed under the bucket bitlock, triggering "sleeping function called from invalid context".
Use a no-ref bucket lookup in this path, then continue duplicate handling without taking a lockref there.
Refactor gfs2_qd_search_bucket() to build on top of the no-ref helper so lookup traversal stays in one place.
This patch fixes a bug reported by syzbot.
