| In the Linux kernel, the following vulnerability has been resolved:
media: v4l: async: Properly re-initialise notifier entry in unregister
The notifier_entry of a notifier is not re-initialised after unregistering
the notifier. This leads to dangling pointers being left there so use
list_del_init() to return the notifier_entry an empty list. |

If p9_check_errors() fails early in p9_client_rpc(), req->rc.tag
will not be properly initialized. However, trace_9p_client_res()
ends up trying to print it out anyway before p9_client_rpc()
finishes.
Fix this issue by assigning default values to p9_fcall fields
such as 'tag' and (just in case KMSAN unearths something new) 'id'
during the tag allocation stage. |
| In the Linux kernel, the following vulnerability has been resolved:
crypto: qat - validate slices count returned by FW
The function adf_send_admin_tl_start() enables the telemetry (TL)
feature on a QAT device by sending the ICP_QAT_FW_TL_START message to
the firmware. This triggers the FW to start writing TL data to a DMA
buffer in memory and returns an array containing the number of
accelerators of each type (slices) supported by this HW.
The pointer to this array is stored in the adf_tl_hw_data data
structure called slice_cnt.
The array slice_cnt is then used in the function tl_print_dev_data()
to report in debugfs only statistics about the supported accelerators.
An incorrect value of the elements in slice_cnt might lead to an out
of bounds memory read.
At the moment, there isn't an implementation of FW that returns a wrong
value, but for robustness validate the slice count array returned by FW. |

=====================================================
The following simple reproducer can cause the issue described above:
int main(void)
{
int sock;
struct sockaddr_vm addr = {
.svm_family = AF_VSOCK,
.svm_cid = VMADDR_CID_ANY,
.svm_port = 1234,
};
sock = socket(AF_VSOCK, SOCK_STREAM, 0);
connect(sock, (struct sockaddr *)&addr, sizeof(addr));
return 0;
}
This issue occurs because the `buf_alloc` and `fwd_cnt` fields of the
`struct virtio_vsock_hdr` are not initialized when a new skb is allocated
in `virtio_transport_init_hdr()`. This patch resolves the issue by
initializing these fields during allocation. |

mm/mempolicy: do not allow illegal MPOL_F_NUMA_BALANCING | MPOL_LOCAL in mbind()
syzbot reported access to unitialized memory in mbind() [1]
Issue came with commit bda420b98505 ("numa balancing: migrate on fault
among multiple bound nodes")
This commit added a new bit in MPOL_MODE_FLAGS, but only checked valid
combination (MPOL_F_NUMA_BALANCING can only be used with MPOL_BIND) in
do_set_mempolicy()
This patch moves the check in sanitize_mpol_flags() so that it is also
used by mbind()

IB/mlx5: Fix initializing CQ fragments buffer
The function init_cq_frag_buf() can be called to initialize the current CQ
fragments buffer cq->buf, or the temporary cq->resize_buf that is filled
during CQ resize operation.
However, the offending commit started to use function get_cqe() for
getting the CQEs, the issue with this change is that get_cqe() always
returns CQEs from cq->buf, which leads us to initialize the wrong buffer,
and in case of enlarging the CQ we try to access elements beyond the size
of the current cq->buf and eventually hit a kernel panic.

| In the Linux kernel, the following vulnerability has been resolved:
cfg80211: call cfg80211_stop_ap when switch from P2P_GO type
If the userspace tools switch from NL80211_IFTYPE_P2P_GO to
NL80211_IFTYPE_ADHOC via send_msg(NL80211_CMD_SET_INTERFACE), it
does not call the cleanup cfg80211_stop_ap(), this leads to the
initialization of in-use data. For example, this path re-init the
sdata->assigned_chanctx_list while it is still an element of
assigned_vifs list, and makes that linked list corrupt. |
| In the Linux kernel, the following vulnerability has been resolved:
Input: appletouch - initialize work before device registration
Syzbot has reported warning in __flush_work(). This warning is caused by
work->func == NULL, which means missing work initialization.
This may happen, since input_dev->close() calls
cancel_work_sync(&dev->work), but dev->work initalization happens _after_
input_register_device() call.
So this patch moves dev->work initialization before registering input

| External initialization of trusted variables or data stores vulnerability exists in WordPress Popular Posts 6.0.5 and earlier, therefore the vulnerable product accepts untrusted external inputs to update certain internal variables. As a result, the number of views for an article may be manipulated through a crafted input. |
| OpenZeppelin Contracts is a library for secure smart contract development. Before version 4.4.1 but after 3.2.0, initializer functions that are invoked separate from contract creation (the most prominent example being minimal proxies) may be reentered if they make an untrusted non-view external call. Once an initializer has finished running it can never be re-executed. However, an exception put in place to support multiple inheritance made reentrancy possible in the scenario described above, breaking the expectation that there is a single execution. Note that upgradeable proxies are commonly initialized together with contract creation, where reentrancy is not feasible, so the impact of this issue is believed to be minor. This issue has been patched, please upgrade to version 4.4.1. As a workaround, avoid untrusted external calls during initialization. |
| NodeBB is an open source Node.js based forum software. Due to a plain object with a prototype being used in socket.io message handling a specially crafted payload can be used to impersonate other users and takeover accounts. This vulnerability has been patched in version 2.6.1. Users are advised to upgrade. Users unable to upgrade may cherry-pick commit `48d143921753914da45926cca6370a92ed0c46b8` into their codebase to patch the exploit.

| Openshift 4.9 does not use HTTP Strict Transport Security (HSTS) which may allow man-in-the-middle (MITM) attacks. |
| Elrond go is the go implementation for the Elrond Network protocol. In versions prior to 1.3.35, read only calls between contracts can generate smart contracts results. For example, if contract A calls in read only mode contract B and the called function will make changes upon the contract's B state, the state will be altered for contract B as if the call was not made in the read-only mode. This can lead to some effects not designed by the original smart contracts programmers. This issue was patched in version 1.3.35. There are no known workarounds. |
| CodeIgniter is a PHP full-stack web framework. In versions prior to 4.2.7 setting `$secure` or `$httponly` value to `true` in `Config\Cookie` is not reflected in `set_cookie()` or `Response::setCookie()`. As a result cookie values are erroneously exposed to scripts. It should be noted that this vulnerability does not affect session cookies. Users are advised to upgrade to v4.2.7 or later. Users unable to upgrade are advised to manually construct their cookies either by setting the options in code or by constructing Cookie objects. Examples of each workaround are available in the linked GHSA. |
| A vulnerability within the firewall configuration of the Cisco Application Policy Infrastructure Controller Enterprise Module (APIC-EM) could allow an unauthenticated, adjacent attacker to gain privileged access to services only available on the internal network of the device. The vulnerability is due to an incorrect firewall rule on the device. The misconfiguration could allow traffic sent to the public interface of the device to be forwarded to the internal virtual network of the APIC-EM. An attacker that is logically adjacent to the network on which the public interface of the affected APIC-EM resides could leverage this behavior to gain access to services listening on the internal network with elevated privileges. This vulnerability affects appliances or virtual devices running Cisco Application Policy Infrastructure Controller Enterprise Module prior to version 1.5. Cisco Bug IDs: CSCve89638. |
| The server daemons in Kannel 1.5.0 and earlier create a PID file after dropping privileges to a non-root account, which might allow local users to kill arbitrary processes by leveraging access to this non-root account for PID file modification before a root script executes a "kill `cat /pathname`" command, as demonstrated by bearerbox. |
| In ImageMagick before 6.9.7-6 and 7.x before 7.0.4-6, the ReadMATImage function in coders/mat.c uses uninitialized data, which might allow remote attackers to obtain sensitive information from process memory. |
