In the Linux kernel, the following vulnerability has been resolved: schedext: Build the cid tables privately and publish them with RCU The cid tables are visible to the cid kfuncs while being modified: the first enable publishes the global pointers before filling them, ops.initcids overrides...

UBUNTU-CVE-2026-99010

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: RFCOMM: free the skb when the DLC has no owner rfcommrecvdata hands the skb to d-dataready and returns 0 without freeing it, so the callback owns the skb from that point on. The tty implementation frees it when the DLC...

In the Linux kernel, the following vulnerability has been resolved: xen/netfront: don't leak the skb when xennetfillfrags fails When a response chain has more slots than fit in the skb's frags, xennetfillfrags returns an error and xennetpoll jumps to its error path. That path moves what's left on...
