| In the Linux kernel, the following vulnerability has been resolved:
vxlan: require CAP_NET_ADMIN in the device netns for changelink
A tunnel changelink() operates on at most two netns, dev_net(dev) and
the sticky underlay netns vxlan->net. They differ once the device is
created in or moved to a netns other than the one the request runs in.
The rtnl changelink path checks CAP_NET_ADMIN only against dev_net(dev),
so a caller privileged there but not in vxlan->net can rewrite a vxlan
device whose underlay lives in vxlan->net.
vxlan_changelink() validates and applies the new configuration against
vxlan->net (vxlan_config_validate(vxlan->net, ...)) and can reopen the
underlay socket in that netns, so the same reasoning as the tunnel
changelink series applies here.
Gate vxlan_changelink() with rtnl_dev_link_net_capable(), at the top of
the op before any attribute is parsed, matching ipgre_changelink() and
the rest of the "require CAP_NET_ADMIN in the device netns for
changelink" series.

| OpenWrt LuCI contains an overly permissive ACL definition in luci-mod-system-mounts that grants write access to /etc/crontabs/root to users intended only for mount configuration. Authenticated users with only the mount-configuration ACL group can append arbitrary cron entries via ubus file.write, which the default busybox crond daemon executes as root within one minute. |
| filebrowser through 2.63.16 fails to properly restrict scope and permissions when self-signup is enabled with default CreateUserDir setting. Unauthenticated attackers can register accounts that inherit the server root scope with full create, modify, delete, rename, share, and download permissions, allowing unrestricted access to all files. |

geneve: require CAP_NET_ADMIN in the device netns for changelink
A tunnel changelink() operates on at most two netns, dev_net(dev) and
the sticky underlay netns geneve->net. They differ once the device is
created in or moved to a netns other than the one the request runs in.
The rtnl changelink path checks CAP_NET_ADMIN only against dev_net(dev),
so a caller privileged there but not in geneve->net can rewrite a geneve
device whose underlay lives in geneve->net.
geneve_changelink() applies the new configuration against geneve->net:
geneve_link_config() and the geneve_quiesce()/geneve_unquiesce() pair
reopen the underlay sockets in that netns (geneve_sock_add() uses
geneve->net), so the same reasoning as the tunnel changelink series
applies here.
Gate geneve_changelink() with rtnl_dev_link_net_capable(), at the top of
the op before any attribute is parsed, matching ipgre_changelink() and
the rest of the "require CAP_NET_ADMIN in the device netns for
changelink" series.

| In the Linux kernel, the following vulnerability has been resolved:
9p: fix access mode flags being ORed instead of replaced
Since commit 1f3e4142c0eb ("9p: convert to the new mount API"),
v9fs_apply_options() applies parsed mount flags with |= onto flags
already set by v9fs_session_init(). For 9P2000.L, session_init sets
V9FS_ACCESS_CLIENT as the default, so when the user mounts with
"access=user", both bits end up set. Access mode checks compare
against exact values, so having both bits set matches neither mode.
This causes v9fs_fid_lookup() to fall through to the default switch
case, using INVALID_UID (nobody/65534) instead of current_fsuid()
for all fid lookups. Root is then unable to chown or perform other
privileged operations.
Fix by clearing the access mask before applying the user's choice. |
| A vulnerability has been found in Uasoft Badaso 3.0.0-alpha. This vulnerability affects the function ApiRequest::class of the file src/Routes/api.php of the component File API. The manipulation leads to permission issues. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. The project was informed of the problem early through an issue report but has not responded yet. |

| In the Linux kernel, the following vulnerability has been resolved:
net: psp: require admin permission for dev-set and key-rotate
The dev-set and key-rotate netlink operations modify shared device
state (PSP version configuration and cryptographic key material,
respectively) but do not require CAP_NET_ADMIN. The only access
control is psp_dev_check_access() which merely verifies netns
membership. |
| In the Linux kernel, the following vulnerability has been resolved:
ovl: check access to copy_file_range source with src mounter creds
Commit 5dae222a5ff0c ("vfs: allow copy_file_range to copy across devices")
allowed filesystems that implement the copy_file_range() f_op to decide
if they want to access cross-sb copy from/to the same fs type.
The same commit added checks to verify same sb copy for filesystems that
implement ->copy_file_range() and do not support cross-sb copy at the
time, namely, to ceph, fuse and nfs.
The two remaining fs which implement ->copy_file_range(), cifs and
overlayfs started to support cross-sb copy from this time.
While overlayfs does support cross-sb copy when the two underlying files
are on the same base fs, the copy operation on the two real files from
two different overalyfs filesystems is performed with the mounter
creds of the destination overlayfs and the read permission access hook
for the source file was called with the wrong creds.
This could cause either deny of access to copy which would otherwise be
allowed (e.g. with splice) or allow read access to file which would
otherwise be denied.
Fix the latter case by explicitly verifying read access to source file
with the source overlayfs mounter creds.
The former case remains a quirk of cross-sb overlayfs copy, but
userspace could fall back to regular copy so no harm done. |
| GitLab has remediated an issue in GitLab EE affecting all versions from 15.6 before 19.0.6, 19.1 before 19.1.4, and 19.2 before 19.2.2 that under certain conditions could have allowed a user with a pending membership to receive permissions granted by a custom role, due to incorrect privilege assignment that did not account for membership state. |
| Improper handling of values for some Intel(R) Processors within Ring 0: Kernel, Hypervisor and Bare Metal OS may allow an escalation of privilege. Authorized adversary with a privileged user combined with a high complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present with special internal knowledge and require no user interaction. The potential vulnerability may impact the confidentiality (low), integrity (low) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (high), integrity (high) and availability (none) impacts. |
| A flaw was found in acm-search-v2-api-rhel9. When the `getFederationConfig` function refreshes its cache, it improperly reuses a user's bearer token for all subsequent federated requests until the cache expires. This allows other authenticated users to gain unauthorized access to remote managed hub search results, leading to information disclosure. |
| Incorrect database cloning process in Plesk from 18.0.52 before 18.0.79.6 and 18.0.80.2 allows a low-privileged user (customer, reseller) to execute arbitrary code on behalf of the database server administrator. |
| A flaw was found in the trustyai-service-operator's LMEvalJob controller. An authenticated user within the cluster can exploit this vulnerability by configuring a sidecar container to bypass existing security policies. This allows the user to enable and execute untrusted remote code, leading to arbitrary code execution within the cluster. |
| In ssh-agent in OpenSSH before 10.5, some operations can occur remotely but were intended to occur only locally, including operations that add tokens or use keys. This is caused by misinteraction between agent locking and the [email protected] extension. |
