| In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: Fix crash caused by calling __xfrm_state_delete() twice
The km.state is not checked in driver's delayed work. When
xfrm_state_check_expire() is called, the state can be reset to
XFRM_STATE_EXPIRED, even if it is XFRM_STATE_DEAD already. This
happens when xfrm state is deleted, but not freed yet. As
__xfrm_state_delete() is called again in xfrm timer, the following
crash occurs.
To fix this issue, skip xfrm_state_check_expire() if km.state is not
XFRM_STATE_VALID.

| In the Linux kernel, the following vulnerability has been resolved:
drm/xe: Use reserved copy engine for user binds on faulting devices
User binds map to engines with can fault, faults depend on user binds
completion, thus we can deadlock. Avoid this by using reserved copy
engine for user binds on faulting devices.
While we are here, normalize bind queue creation with a helper.
v2:
- Pass in extensions to bind queue creation (CI)
v3:
- s/resevered/reserved (Lucas)
- Fix NULL hwe check (Jonathan) |
| In the Linux kernel, the following vulnerability has been resolved:
pinctrl: qcom: x1e80100: Fix special pin offsets
Remove the erroneus 0x100000 offset to prevent the boards from crashing
on pin state setting, as well as for the intended state changes to take
effect. |
| In the Linux kernel, the following vulnerability has been resolved:
vsock: fix recursive ->recvmsg calls
After a vsock socket has been added to a BPF sockmap, its prot->recvmsg
has been replaced with vsock_bpf_recvmsg(). Thus the following
recursiion could happen:
vsock_bpf_recvmsg()
-> __vsock_recvmsg()
-> vsock_connectible_recvmsg()
-> prot->recvmsg()
-> vsock_bpf_recvmsg() again
We need to fix it by calling the original ->recvmsg() without any BPF
sockmap logic in __vsock_recvmsg(). |
| In the Linux kernel, the following vulnerability has been resolved:
mm/damon/sysfs: fix wrong empty schemes assumption under online tuning in damon_sysfs_set_schemes()
Commit da87878010e5 ("mm/damon/sysfs: support online inputs update") made
'damon_sysfs_set_schemes()' to be called for running DAMON context, which
could have schemes. In the case, DAMON sysfs interface is supposed to
update, remove, or add schemes to reflect the sysfs files. However, the
code is assuming the DAMON context wouldn't have schemes at all, and
therefore creates and adds new schemes. As a result, the code doesn't
work as intended for online schemes tuning and could have more than
expected memory footprint. The schemes are all in the DAMON context, so
it doesn't leak the memory, though.
Remove the wrong asssumption (the DAMON context wouldn't have schemes) in
'damon_sysfs_set_schemes()' to fix the bug. |
| Hyperledger Fabric 2.3 allows attackers to cause a denial of service (orderer crash) by repeatedly sending a crafted channel tx with the same Channel name. NOTE: the official Fabric with Raft prevents exploitation via a locking mechanism and a check for names that already exist. |
| An issue was discovered in MaraDNS Deadwood through 3.5.0021 that allows variant V1 of unintended domain name resolution. A revoked domain name can still be resolvable for a long time, including expired domains and taken-down malicious domains. The effects of an exploit would be widespread and highly impactful, because the exploitation conforms to de facto DNS specifications and operational practices, and overcomes current mitigation patches for "Ghost" domain names. |
| Mastodon through 4.0.2 allows attackers to cause a denial of service (large Sidekiq pull queue) by creating bot accounts that follow attacker-controlled accounts on certain other servers associated with a wildcard DNS A record, such that there is uncontrolled recursion of attacker-generated messages. |
| Vyper is a Pythonic Smart Contract Language for the EVM. When the Vyper Compiler uses the precompiles EcRecover (0x1) and Identity (0x4), the success flag of the call is not checked. As a consequence an attacker can provide a specific amount of gas to make these calls fail but let the overall execution continue. Then the execution result can be incorrect. Based on EVM's rules, after the failed precompile the remaining code has only 1/64 of the pre-call-gas left (as 63/64 were forwarded and spent). Hence, only fairly simple executions can follow the failed precompile calls. Therefore, we found no significantly impacted real-world contracts. None the less an advisory has been made out of an abundance of caution. This issue is fixed in 0.4.1. |
| Decidim is a participatory democracy framework. Starting in version 0.4.rc3 and prior to version 2.0.9 of the `devise_invitable` gem, the invites feature allows users to accept the invitation for an unlimited amount of time through the password reset functionality. This issue creates vulnerable dependencies starting in version 0.0.1.alpha3 and prior to versions 0.26.9, 0.27.5, and 0.28.0 of the `decidim,` `decidim-admin`, and `decidim-system` gems. When using the password reset functionality, the `devise_invitable` gem always accepts the pending invitation if the user has been invited. The only check done is if the user has been invited but the code does not ensure that the pending invitation is still valid as defined by the `invite_for` expiry period. Decidim sets this configuration to `2.weeks` so this configuration should be respected. The bug is in the `devise_invitable` gem and should be fixed there and the dependency should be upgraded in Decidim once the fix becomes available. `devise_invitable` to version `2.0.9` and above fix this issue. Versions 0.26.9, 0.27.5, and 0.28.0 of the `decidim,` `decidim-admin`, and `decidim-system` gems contain this fix. As a workaround, invitations can be cancelled directly from the database. |
| Istio is an open platform to connect, manage, and secure microservices. In Istio 1.12.0 and 1.12.1 The authorization policy with hosts and notHosts might be accidentally bypassed for ALLOW action or rejected unexpectedly for DENY action during the upgrade from 1.11 to 1.12.0/1.12.1. Istio 1.12 supports the hosts and notHosts fields in authorization policy with a new Envoy API shipped with the 1.12 data plane. A bug in the 1.12.0 and 1.12.1 incorrectly uses the new Envoy API with the 1.11 data plane. This will cause the hosts and notHosts fields to be always matched regardless of the actual value of the host header when mixing 1.12.0/1.12.1 control plane and 1.11 data plane. Users are advised to upgrade or to not mix the 1.12.0/1.12.1 control plane with 1.11 data plane if using hosts or notHosts field in authorization policy. |
| graphql-go is a GraphQL server with a focus on ease of use. In versions prior to 1.3.0 there exists a DoS vulnerability that is possible due to a bug in the library that would allow an attacker with specifically designed queries to cause stack overflow panics. Any user with access to the GraphQL handler can send these queries and cause stack overflows. This in turn could potentially compromise the ability of the server to serve data to its users. The issue has been patched in version `v1.3.0`. The only known workaround for this issue is to disable the `graphql.MaxDepth` option from your schema which is not recommended. |
| Tensorflow is an Open Source Machine Learning Framework. The `GraphDef` format in TensorFlow does not allow self recursive functions. The runtime assumes that this invariant is satisfied. However, a `GraphDef` containing a fragment such as the following can be consumed when loading a `SavedModel`. This would result in a stack overflow during execution as resolving each `NodeDef` means resolving the function itself and its nodes. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range. |
| Envoy is an open source edge and service proxy, designed for cloud-native applications. When a cluster is deleted via Cluster Discovery Service (CDS) all idle connections established to endpoints in that cluster are disconnected. A recursion was introduced in the procedure of disconnecting idle connections that can lead to stack exhaustion and abnormal process termination when a cluster has a large number of idle connections. This infinite recursion causes Envoy to crash. Users are advised to upgrade. |
| Envoy is an open source edge and service proxy, designed for cloud-native applications. The envoy common router will segfault if an internal redirect selects a route configured with direct response or redirect actions. This will result in a denial of service. As a workaround turn off internal redirects if direct response entries are configured on the same listener. |
| Nextcloud Server is the file server software for Nextcloud, a self-hosted productivity platform. Prior to versions 22.2.6 and 23.0.3, a user can create a link that is not password protected even if the administrator requires links to be password protected. Versions 22.2.6 and 23.0.3 contain a patch for this issue. There are currently no known workarounds. |
| Zulip is an open-source team collaboration tool. Versions 2.1.0 through and including 5.2 are vulnerable to a logic error. A stream configured as private with protected history, where new subscribers should not be allowed to see messages sent before they were subscribed, when edited causes the server to incorrectly send an API event that includes the edited message to all of the stream’s current subscribers. This API event is ignored by official clients, but can be observed by using a modified client or the browser’s developer tools. This bug will be fixed in Zulip Server 5.3. There are no known workarounds. |
| rulex is a new, portable, regular expression language. When parsing untrusted rulex expressions, the stack may overflow, possibly enabling a Denial of Service attack. This happens when parsing an expression with several hundred levels of nesting, causing the process to abort immediately. This is a security concern for you, if your service parses untrusted rulex expressions (expressions provided by an untrusted user), and your service becomes unavailable when the process running rulex aborts due to a stack overflow. The crash is fixed in version **0.4.3**. Affected users are advised to update to this version. There are no known workarounds for this issue. |
| Synapse is an open source home server implementation for the Matrix chat network. In versions prior to 1.61.1 URL previews of some web pages can exhaust the available stack space for the Synapse process due to unbounded recursion. This is sometimes recoverable and leads to an error for the request causing the problem, but in other cases the Synapse process may crash altogether. It is possible to exploit this maliciously, either by malicious users on the homeserver, or by remote users sending URLs that a local user's client may automatically request a URL preview for. Remote users are not able to exploit this directly, because the URL preview endpoint is authenticated. Deployments with `url_preview_enabled: false` set in configuration are not affected. Deployments with `url_preview_enabled: true` set in configuration **are** affected. Deployments with no configuration value set for `url_preview_enabled` are not affected, because the default is `false`. Administrators of homeservers with URL previews enabled are advised to upgrade to v1.61.1 or higher. Users unable to upgrade should set `url_preview_enabled` to false. |
