No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

In the Linux kernel, the following vulnerability has been resolved:

gfs2: move quota_init qc iterator increment

Move qc++ from the loop body into the for-loop increment expression in gfs2_quota_init().

This keeps iterator progression explicit and avoids mixing pointer advance with duplicate-slot handling in the loop body.
