Security Fix(es):
|
|
|
|
In the Linux kernel, the following vulnerability has been resolved:
|
|
|
|
scsi: core: Fix scsi_mode_sense() buffer length handling
|
|
|
|
Several problems exist with scsi_mode_sense() buffer length handling:
|
|
|
|
1) The allocation length field of the MODE SENSE(10) command is 16-bits,
|
|
occupying bytes 7 and 8 of the CDB. With this command, access to mode
|
|
pages larger than 255 bytes is thus possible. However, the CDB
|
|
allocation length field is set by assigning len to byte 8 only, thus
|
|
truncating buffer length larger than 255.
|
|
|
|
2) If scsi_mode_sense() is called with len smaller than 8 with
|
|
sdev->use_10_for_ms set, or smaller than 4 otherwise, the buffer length
|
|
is increased to 8 and 4 respectively, and the buffer is zero filled
|
|
with these increased values, thus corrupting the memory following the
|
|
buffer.
|
|
|
|
Fix these 2 problems by using put_unaligned_be16() to set the allocation
|
|
length field of MODE SENSE(10) CDB and by returning an error when len is
|
|
too small.
|
|
|
|
Furthermore, if len is larger than 255B, always try MODE SENSE(10) first,
|
|
even if the device driver did not set sdev->use_10_for_ms. In case of
|
|
invalid opcode error for MODE SENSE(10), access to mode pages larger than
|
|
255 bytes are not retried using MODE SENSE(6). To avoid buffer length
|
|
overflows for the MODE_SENSE(10) case, check that len is smaller than 65535
|
|
bytes.
|
|
|
|
While at it, also fix the folowing:
|
|
|
|
* Use get_unaligned_be16() to retrieve the mode data length and block
|
|
descriptor length fields of the mode sense reply header instead of using
|
|
an open coded calculation.
|
|
|
|
* Fix the kdoc dbd argument explanation: the DBD bit stands for Disable
|
|
Block Descriptor, which is the opposite of what the dbd argument
|
|
description was.(CVE-2021-47182)
|
|
|
|
In the Linux kernel, the following vulnerability has been resolved:
|
|
|
|
ALSA: usb-audio: fix null pointer dereference on pointer cs_desc
|
|
|
|
The pointer cs_desc return from snd_usb_find_clock_source could
|
|
be null, so there is a potential null pointer dereference issue.
|
|
Fix this by adding a null check before dereference.(CVE-2021-47211)
|
|
|
|
In the Linux kernel, the following vulnerability has been resolved:
|
|
|
|
l2tp: pass correct message length to ip6_append_data
|
|
|
|
l2tp_ip6_sendmsg needs to avoid accounting for the transport header
|
|
twice when splicing more data into an already partially-occupied skbuff.
|
|
|
|
To manage this, we check whether the skbuff contains data using
|
|
skb_queue_empty when deciding how much data to append using
|
|
ip6_append_data.
|
|
|
|
However, the code which performed the calculation was incorrect:
|
|
|
|
ulen = len + skb_queue_empty(&sk->sk_write_queue) ? transhdrlen : 0;
|
|
|
|
...due to C operator precedence, this ends up setting ulen to
|
|
transhdrlen for messages with a non-zero length, which results in
|
|
corrupted packets on the wire.
|
|
|
|
Add parentheses to correct the calculation in line with the original
|
|
intent.(CVE-2024-26752)</Note>
