| In the Linux kernel, the following vulnerability has been resolved:
net: skbuff: propagate shared-frag marker in skb_zerocopy()
skb_zerocopy() moves frag descriptors from @from into @to and takes a
reference on each frag, but it does not copy skb_shinfo(from)->flags into
skb_shinfo(to)->flags. A destination skb holding the same page-cache
backed frags as the source therefore reports skb_has_shared_frag() as
false.
That breaks the invariant relied on by later in-place writers. ESP input
checks skb_has_shared_frag() before deciding whether an uncloned
nonlinear skb can skip skb_cow_data(); with the marker lost, an skb that
skb_zerocopy() built for nfnetlink_queue or for an openvswitch upcall is
decrypted in place, letting an unprivileged user write into the page
cache of a root-owned read-only file.
Propagate SKBFL_SHARED_FRAG when frag descriptors are copied, as done for
the other frag-transfer helpers. |

| In the Linux kernel, the following vulnerability has been resolved:
netfilter: conntrack: tcp: use UNACK timeout for non-closing RST packets
Commit be0502a3f2e9 ("netfilter: conntrack: tcp: only close if RST
matches exact sequence") keeps an established conntrack entry in
ESTABLISHED when an in-window RST does not match the expected sequence
number exactly, so the endpoint can validate the RST with a challenge
ACK.
The timeout selection nevertheless uses the CLOSE timeout for every RST
packet. The bug is that timeout selection is based on the packet type,
not on the state transition result: even when RST validation keeps
new_state in ESTABLISHED, the timeout is still forced to
TCP_CONNTRACK_CLOSE.
Linux TCP independently rate limits challenge ACKs per socket. A second
non-exact RST can therefore arrive after the first challenge ACK has
restored the timeout but before the rate limit expires. The second RST
lowers the timeout to 10 seconds again while the endpoint suppresses the
second challenge ACK, allowing the conntrack entry to expire while both
TCP endpoints remain established.
Using the ESTABLISHED timeout for such RSTs would avoid this short
expiration window, but it could also retain stale entries for the
five-day default because conntrack cannot reliably match the endpoint's
exact TCP state.
Use the UNACK timeout for RST packets that leave the conntrack entry in
TCP_CONNTRACK_ESTABLISHED. Exact-match RSTs and accepted RST packet
trains still fall through to timeouts[new_state], which preserves the
CLOSE timeout when conntrack accepts the RST as closing the flow.
This avoids the aggressive 10-second expiration window for non-exact
RSTs while preserving the short timeout for RSTs that conntrack accepts
as closing the flow. |

| In the Linux kernel, the following vulnerability has been resolved:
net/sched: sch_teql: fix use-after-free on lower qdisc drop
The issue: teql_master_xmit() tests the slave's ndo_start_xmit() return
value against NETDEV_TX_OK alone. A slave that consumes the skb but
returns an error code (rc < NET_XMIT_MASK, e.g. NET_XMIT_DROP) is treated
as if the skb were still owned, so the loop restores skb->dev and calls
__skb_pull() on it. A VLAN slave returns the result of dev_queue_xmit()
from its ndo_start_xmit() (propagated since cbbef5e18307), and when the
lower qdisc drops the packet that value is NET_XMIT_DROP after the skb
has been freed, giving a use-after-free in teql_master_xmit().
The Fix: test for consumption with dev_xmit_complete(), which accepts
NETDEV_TX_OK and every rc < NET_XMIT_MASK, matching other callers that
need to distinguish consumed results from busy. Only NETDEV_TX_OK keeps
the packet counted in tx_packets/tx_bytes and advances the slave; a
consumed result that is neither a success nor NET_XMIT_CN ends the
attempt and is charged to tx_dropped, so lower-qdisc drops are no longer
reported as good transmits. NET_XMIT_CN is counted like success because
it can accompany acceptance of the current packet: pfifo_head_drop drops
the old head, enqueues the current skb and returns NET_XMIT_CN.
Conditions to recreate the bug:
With CONFIG_NET_SCH_TEQL,
CONFIG_VLAN_8021Q and CONFIG_DUMMY enabled, add lkrdummy0 (dummy) and
lkrvlan0 (VLAN id 37 on lkrdummy0); set a pfifo limit 0 root on lkrdummy0
and a teql0 root on lkrvlan0; bring teql0 up with an address and send one
UDP packet to it. The VLAN xmit returns NET_XMIT_DROP from the lower
qdisc while holding a freed skb. |
