This issue is caused by a race between mbind() and VMA-locked page fault, and may allow a local attacker to crash the system or lead to a kernel information leak. We recommend upgrading past commit 790c2f9d15b594350ae9bca7b236f2b1859de02c.Ī use-after-free flaw was found in mm/mempolicy.c in the memory management subsystem in the Linux Kernel. Thus there is a race where unix_stream_sendpage() could access an skb locklessly that is being released by garbage collection, resulting in use-after-free. The unix_stream_sendpage() function tries to add data to the last skb in the peer's recv queue without locking the queue.

This leaves a dangling pointer that can cause a use-after-free. with the HFSC_FSC flag set) has a parent without a link-sharing curve, then init_vf() will call vttree_insert() on the parent, but vttree_remove() will be skipped in update_vf().

When the plug qdisc is used as a class of the qfq qdisc, sending network packets triggers use-after-free in qfq_dequeue() due to the incorrect.
