CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: function: rndis: add length check for header
Add a length check for the rndis header in rndis_rm_hdr, to ensure that
MessageType, MessageLength, DataOffset, and DataLength fields are
present before they are accessed. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: accel: bmc150: clamp the device-reported FIFO frame count
__bmc150_accel_fifo_flush() copies the number of samples the device
reports in its hardware FIFO into an on-stack buffer
u16 buffer[BMC150_ACCEL_FIFO_LENGTH * 3];
which is sized for at most BMC150_ACCEL_FIFO_LENGTH (32) samples. The
frame count is read from the FIFO_STATUS register and only masked to its
7 valid bits:
count = val & 0x7F;
so it can be 0..127. The only other limit applied to it is the optional
caller-supplied sample budget:
if (samples && count > samples)
count = samples;
which does not constrain count on the flush-all path (samples == 0), and
leaves it well above 32 whenever samples is larger. count samples are
then transferred into buffer[]:
bmc150_accel_fifo_transfer(data, (u8 *)buffer, count);
bmc150_accel_fifo_transfer() reads count * 6 bytes through regmap, so a
malfunctioning, malicious or counterfeit accelerometer (or an attacker
tampering with the I2C/SPI bus) that reports up to 127 frames writes up
to 762 bytes into the 192-byte buffer: a stack out-of-bounds write of up
to 570 bytes that clobbers the stack canary, saved registers and the
return address.
Clamp count to BMC150_ACCEL_FIFO_LENGTH, the number of samples buffer[]
is sized for, before the transfer, mirroring the watermark clamp already
done in bmc150_accel_set_watermark(). A well-formed flush reports at most
BMC150_ACCEL_FIFO_LENGTH frames, so legitimate devices are unaffected. |
| In the Linux kernel, the following vulnerability has been resolved:
ipv4: free inet_opt and ireq_opt after an RCU grace period
tcp_v4_syn_recv_sock() transfers ownership of ireq->ireq_opt to the
child socket (newinet->inet_opt) without copying it.
Another cpu can concurrently process a retransmitted SYN for the same
request socket, and send a SYNACK from tcp_check_req().
tcp_v4_send_synack() and inet_csk_route_req() read ireq->ireq_opt
under rcu_read_lock() only, and ip_build_and_send_pkt() and
ip_options_build() then read opt->optlen twice.
Note that the SYNACK timer itself is not an issue: it holds a
reference on its request socket, and inet_csk_reqsk_queue_drop()
calls timer_delete_sync() before the child can be freed.
Since commit 079096f103fa ("tcp/dccp: install syn_recv requests
into ehash table"), request sockets are processed without holding
the listener lock, so nothing prevents the child socket from being
freed while the SYNACK is still being built. TCP child sockets do
not have SOCK_RCU_FREE, and inet_sock_destruct() frees inet_opt
with a plain kfree(), leading to a use-after-free in
ip_options_build().
A similar issue exists with request socket migration
(net.ipv4.tcp_migrate_req=1, or a BPF_SK_REUSEPORT_SELECT_OR_MIGRATE
program). reqsk_timer_handler() clones the request socket with
inet_reqsk_clone(), so that the old request socket and its clone
share the same ireq_opt, then reqsk_migrate_reset() clears the
pointer in the old one. Another cpu holding a reference on the old
request socket can still be using these options (sending a SYNACK,
or creating a child in tcp_v4_syn_recv_sock()) when the clone is
freed, and tcp_v4_reqsk_destructor() also uses a plain kfree().
Readers already use RCU, and other paths replacing inet_opt
(do_ip_setsockopt(), cipso_v4_sock_setattr()...) already use
kfree_rcu(). Use kfree_rcu() in inet_sock_destruct() and
tcp_v4_reqsk_destructor() as well.
IPv6 is not affected by the first issue, because tcp_v6_syn_recv_sock()
duplicates the options. tcp_v6_reqsk_destructor() has the same
migration issue with ipv6_opt, which is only set by CALIPSO. This
will be addressed in a separate patch. |
