Linux: >> Linux Kernel >> 2.6.27.25 Security Vulnerabilities
In the Linux kernel, the following vulnerability has been resolved:
net: tulip: de4x5: fix the problem that the array 'lp->phy[8]' may be out of bound
In line 5001, if all id in the array 'lp->phy[8]' is not 0, when the
'for' end, the 'k' is 8.
At this time, the array 'lp->phy[8]' may be out of bound.

In the Linux kernel, the following vulnerability has been resolved:
ethernet: hisilicon: hns: hns_dsaf_misc: fix a possible array overflow in hns_dsaf_ge_srst_by_port()
The if statement:
if (port >= DSAF_GE_NUM)
return;
limits the value of port less than DSAF_GE_NUM (i.e., 8).
However, if the value of port is 6 or 7, an array overflow could occur:
port_rst_off = dsaf_dev->mac_cb[port]->port_rst_off;
because the length of dsaf_dev->mac_cb is DSAF_MAX_PORT_NUM (i.e., 6).
To fix this possible array overflow, we first check port and if it is
greater than or equal to DSAF_MAX_PORT_NUM, the function returns.

In the Linux kernel, the following vulnerability has been resolved:
sata_fsl: fix UAF in sata_fsl_port_stop when rmmod sata_fsl
When the `rmmod sata_fsl.ko` command is executed in the PPC64 GNU/Linux,
a bug is reported:
==================================================================
BUG: Unable to handle kernel data access on read at 0x80000800805b502c
Oops: Kernel access of bad area, sig: 11 [#1]

==================================================================
The triggering of the BUG is shown in the following stack:
driver_detach
device_release_driver_internal
__device_release_driver
drv->remove(dev) --> platform_drv_remove/platform_remove
drv->remove(dev) --> sata_fsl_remove
iounmap(host_priv->hcr_base); <---- unmap
kfree(host_priv); <---- free
devres_release_all
release_nodes
dr->node.release(dev, dr->data) --> ata_host_stop
ap->ops->port_stop(ap) --> sata_fsl_port_stop
ioread32(hcr_base + HCONTROL) <---- UAF
host->ops->host_stop(host)
The iounmap(host_priv->hcr_base) and kfree(host_priv) functions should
not be executed in drv->remove. These functions should be executed in
host_stop after port_stop. Therefore, we move these functions to the
new function sata_fsl_host_stop and bind the new function to host_stop.

In the Linux kernel, the following vulnerability has been resolved:
drm/amd/amdkfd: Fix kernel panic when reset failed and been triggered again
In SRIOV configuration, the reset may failed to bring asic back to normal but stop cpsch
already been called, the start_cpsch will not be called since there is no resume in this
case. When reset been triggered again, driver should avoid to do uninitialization again.

In the Linux kernel, the following vulnerability has been resolved:
HID: bigbenff: prevent null pointer dereference
When emulating the device through uhid, there is a chance we don't have
output reports and so report_field is null.

In the Linux kernel, the following vulnerability has been resolved:
nfsd: fix use-after-free due to delegation race
A delegation break could arrive as soon as we've called vfs_setlease. A
delegation break runs a callback which immediately (in
nfsd4_cb_recall_prepare) adds the delegation to del_recall_lru. If we
then exit nfs4_set_delegation without hashing the delegation, it will be
freed as soon as the callback is done with it, without ever being
removed from del_recall_lru.
Symptoms show up later as use-after-free or list corruption warnings,
usually in the laundromat thread.
I suspect aba2072f4523 "nfsd: grant read delegations to clients holding
writes" made this bug easier to hit, but I looked as far back as v3.0
and it looks to me it already had the same problem. So I'm not sure
where the bug was introduced; it may have been there from the beginning.

In the Linux kernel, the following vulnerability has been resolved:
dm rq: don't queue request to blk-mq during DM suspend
DM uses blk-mq's quiesce/unquiesce to stop/start device mapper queue.
But blk-mq's unquiesce may come from outside events, such as elevator
switch, updating nr_requests or others, and request may come during
suspend, so simply ask for blk-mq to requeue it.
Fixes one kernel panic issue when running updating nr_requests and
dm-mpath suspend/resume stress test.
