CVE-2024-53141 (GCVE-0-2024-53141)

Title
netfilter: ipset: add missing range check in bitmap_ip_uadt
Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: ipset: add missing range check in bitmap_ip_uadt
When tb[IPSET_ATTR_IP_TO] is not present but tb[IPSET_ATTR_CIDR] exists,
the values of ip and ip_to are slightly swapped. Therefore, the range check
for ip should be done later, but this part is missing and it seems that the
vulnerability occurs.
So we should add missing range checks and remove unnecessary range checks.

Title
mptcp: fix NULL pointer in can_accept_new_subflow
Summary
In the Linux kernel, the following vulnerability has been resolved:
mptcp: fix NULL pointer in can_accept_new_subflow
When testing valkey benchmark tool with MPTCP, the kernel panics in
'mptcp_can_accept_new_subflow' because subflow_req->msk is NULL.
Call trace:
mptcp_can_accept_new_subflow (./net/mptcp/subflow.c:63 (discriminator 4)) (P)
subflow_syn_recv_sock (./net/mptcp/subflow.c:854)
tcp_check_req (./net/ipv4/tcp_minisocks.c:863)
tcp_v4_rcv (./net/ipv4/tcp_ipv4.c:2268)
ip_protocol_deliver_rcu (./net/ipv4/ip_input.c:207)
ip_local_deliver_finish (./net/ipv4/ip_input.c:234)
ip_local_deliver (./net/ipv4/ip_input.c:254)
ip_rcv_finish (./net/ipv4/ip_input.c:449)
...
According to the debug log, the same req received two SYN-ACK in a very
short time, very likely because the client retransmits the syn ack due
to multiple reasons.
Even if the packets are transmitted with a relevant time interval, they
can be processed by the server on different CPUs concurrently). The
'subflow_req->msk' ownership is transferred to the subflow the first,
and there will be a risk of a null pointer dereference here.
This patch fixes this issue by moving the 'subflow_req->msk' under the
`own_req == true` conditional.
Note that the !msk check in subflow_hmac_valid() can be dropped, because
the same check already exists under the own_req mpj branch where the
code has been moved to.

Title
xfrm: interface: fix use-after-free after changing collect_md xfrm interface
Summary
In the Linux kernel, the following vulnerability has been resolved:
xfrm: interface: fix use-after-free after changing collect_md xfrm interface
collect_md property on xfrm interfaces can only be set on device creation,
thus xfrmi_changelink() should fail when called on such interfaces.
The check to enforce this was done only in the case where the xi was
returned from xfrmi_locate() which doesn't look for the collect_md
interface, and thus the validation was never reached.
Calling changelink would thus errornously place the special interface xi
in the xfrmi_net->xfrmi hash, but since it also exists in the
xfrmi_net->collect_md_xfrmi pointer it would lead to a double free when
the net namespace was taken down [1].
Change the check to use the xi from netdev_priv which is available earlier
in the function to prevent changes in xfrm collect_md interfaces.

Title
tls: handle data disappearing from under the TLS ULP
Summary
In the Linux kernel, the following vulnerability has been resolved:
tls: handle data disappearing from under the TLS ULP
TLS expects that it owns the receive queue of the TCP socket.
This cannot be guaranteed in case the reader of the TCP socket
entered before the TLS ULP was installed, or uses some non-standard
read API (eg. zerocopy ones). Replace the WARN_ON() and a buggy
early exit (which leaves anchor pointing to a freed skb) with real
error handling. Wipe the parsing state and tell the reader to retry.
We already reload the anchor every time we (re)acquire the socket lock,
so the only condition we need to avoid is an out of bounds read
(not having enough bytes in the socket for previously parsed record len).
If some data was read from under TLS but there's enough in the queue
we'll reload and decrypt what is most likely not a valid TLS record.
Leading to some undefined behavior from TLS perspective (corrupting
a stream? missing an alert? missing an attack?) but no kernel crash
should take place.

Replace the WARN_ON() and a buggy\nearly exit (which leaves anchor pointing to a freed skb) with real\nerror handling. Wipe the parsing state and tell the reader to retry.\n\nWe already reload the anchor every time we (re)acquire the socket lock,\nso the only condition we need to avoid is an out of bounds read\n(not having enough bytes in the socket for previously parsed record len).\n\nIf some data was read from under TLS but there\u0027s enough in the queue\nwe\u0027ll reload and decrypt what is most likely not a valid TLS record.\nLeading to some undefined behavior from TLS perspective (corrupting\na stream? missing an alert? missing an attack?) but no kernel crash\nshould take place."
