drm/amd/display: Fix slab-use-after-free in hdcp
The HDCP code in amdgpu_dm_hdcp.c copies pointers to amdgpu_dm_connector
objects without incrementing the kref reference counts. When using a
USB-C dock, and the dock is unplugged, the corresponding
amdgpu_dm_connector objects are freed, creating dangling pointers in the
HDCP code. When the dock is plugged back, the dangling pointers are
dereferenced, resulting in a slab-use-after-free:

| In the Linux kernel, the following vulnerability has been resolved:
irqchip/qcom-mpm: Prevent crash when trying to handle non-wake GPIOs
On Qualcomm chipsets not all GPIOs are wakeup capable. Those GPIOs do not
have a corresponding MPM pin and should not be handled inside the MPM
driver. The IRQ domain hierarchy is always applied, so it's required to
explicitly disconnect the hierarchy for those. The pinctrl-msm driver marks
these with GPIO_NO_WAKE_IRQ. qcom-pdc has a check for this, but
irq-qcom-mpm is currently missing the check. This is causing crashes when
setting up interrupts for non-wake GPIOs:
root@rb1:~# gpiomon -c gpiochip1 10

Fix this by copying the check for GPIO_NO_WAKE_IRQ from qcom-pdc.c, so that
MPM is removed entirely from the hierarchy for non-wake GPIOs. |

either the open slot or the layoutget operation arguments, since they
are likely still in use by the hung RPC call. |
| In the Linux kernel, the following vulnerability has been resolved:
net: tap: NULL pointer derefence in dev_parse_header_protocol when skb->dev is null
Fixes a NULL pointer derefence bug triggered from tap driver.
When tap_get_user calls virtio_net_hdr_to_skb the skb->dev is null
(in tap.c skb->dev is set after the call to virtio_net_hdr_to_skb)
virtio_net_hdr_to_skb calls dev_parse_header_protocol which
needs skb->dev field to be valid.
The line that trigers the bug is in dev_parse_header_protocol
(dev is at offset 0x10 from skb and is stored in RAX register)
if (!dev->header_ops || !dev->header_ops->parse_protocol)
22e1: mov 0x10(%rbx),%rax
22e5: mov 0x230(%rax),%rax
Setting skb->dev before the call in tap.c fixes the issue.

| An unauthenticated command injection vulnerability exists in the D-Link DIR-878A1 router firmware FW101B04.bin. The vulnerability occurs in the 'SetNetworkSettings' functionality of prog.cgi, where the 'IPAddress' and 'SubnetMask' parameters are directly concatenated into shell commands executed via system(). An attacker can exploit this vulnerability remotely without authentication by sending a specially crafted HTTP request, leading to arbitrary command execution on the device. |
| A stack buffer overflow vulnerability exists in the D-Link DIR-816A2 router firmware DIR-816A2_FWv1.10CNB05_R1B011D88210.img in the upload.cgi module, which handles firmware version information. The vulnerability occurs because /proc/version is read into a 512-byte buffer and then concatenated using sprintf() into another 512-byte buffer containing a 29-byte constant. Input exceeding 481 bytes triggers a stack buffer overflow, allowing an attacker who can control /proc/version content to potentially execute arbitrary code on the device. |

| Mattermost versions <11.0 fail to properly enforce the "Allow users to view archived channels" setting which allows regular users to access archived channel content and files via the "Open in Channel" functionality from followed threads |
| Mattermost versions <11 fail to enforce multi-factor authentication on WebSocket connections which allows unauthenticated users to access sensitive information via WebSocket events |
| Rockwell Automation Arena® suffers from a
stack-based buffer overflow vulnerability. The specific flaw exists within the
parsing of DOE files. Local attackers are able to exploit this issue to
potentially execute arbitrary code on affected installations of Arena®. Exploiting
the vulnerability requires opening a malicious DOE file. |
| Multiple parameters in register.php in PHPGurukul Student Record System 3.20 are vulnerable to SQL injection. These include: c-full, fname, mname,lname, gname, ocp, nation, mobno, email, board1, roll1, pyear1, board2, roll2, pyear2, sub1,marks1, sub2, course-short, income, category, ph, country, state, city, padd, cadd, and gender. |
| A flaw was discovered in libvirt in the XML file processing. More specifically, the parsing of user provided XML files was performed before the ACL checks. A malicious user with limited permissions could exploit this flaw by submitting a specially crafted XML file, causing libvirt to allocate too much memory on the host. The excessive memory consumption could lead to a libvirt process crash on the host, resulting in a denial-of-service condition. |
| PHPGurukul Student Record System 3.20 is vulnerable to SQL Injection via the id and emailid parameters in password-recovery.php. |

| Firmware in KAON AR2140 routers, prior to versions 3.2.50 and 4.2.16, is vulnerable to a shell command injection via sending a crafted request to one of the endpoints.
In order to exploit this vulnerability, one has to have access to the administrative portal of the router. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: ops: Consistently treat platform_max as control value
This reverts commit 9bdd10d57a88 ("ASoC: ops: Shift tested values in
snd_soc_put_volsw() by +min"), and makes some additional related
updates.
There are two ways the platform_max could be interpreted; the maximum
register value, or the maximum value the control can be set to. The
patch moved from treating the value as a control value to a register
one. When the patch was applied it was technically correct as
snd_soc_limit_volume() also used the register interpretation. However,
even then most of the other usages treated platform_max as a
control value, and snd_soc_limit_volume() has since been updated to
also do so in commit fb9ad24485087 ("ASoC: ops: add correct range
check for limiting volume"). That patch however, missed updating
snd_soc_put_volsw() back to the control interpretation, and fixing
snd_soc_info_volsw_range(). The control interpretation makes more
sense as limiting is typically done from the machine driver, so it is
appropriate to use the customer facing representation rather than the
internal codec representation. Update all the code to consistently use
this interpretation of platform_max.
Finally, also add some comments to the soc_mixer_control struct to
hopefully avoid further patches switching between the two approaches. |

net_sched: hfsc: Fix a UAF vulnerability in class with netem as child qdisc
As described in Gerrard's report [1], we have a UAF case when an hfsc class
has a netem child qdisc. The crux of the issue is that hfsc is assuming
that checking for cl->qdisc->q.qlen == 0 guarantees that it hasn't inserted
the class in the vttree or eltree (which is not true for the netem
duplicate case).
This patch checks the n_active class variable to make sure that the code
won't insert the class in the vttree or eltree twice, catering for the
reentrant case.

| In the Linux kernel, the following vulnerability has been resolved:
net_sched: qfq: Fix double list add in class with netem as child qdisc
As described in Gerrard's report [1], there are use cases where a netem
child qdisc will make the parent qdisc's enqueue callback reentrant.
In the case of qfq, there won't be a UAF, but the code will add the same
classifier to the list twice, which will cause memory corruption.
This patch checks whether the class was already added to the agg->active
list (cl_is_active) before doing the addition to cater for the reentrant
case.
