CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
net: ip6_tunnel: require CAP_NET_ADMIN in the device netns for changelink
ip6_tnl_changelink() operates on at most two netns, dev_net(dev) and the
tunnel link netns t->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 t->net can rewrite a tunnel that
lives in t->net.
Gate ip6_tnl_changelink() on rtnl_dev_link_net_capable() at its top,
before any attribute is parsed. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: client: mask server-provided mode to 07777 in modefromsid
When modefromsid is active, parse_dacl() applies the server-provided
sub_auth[2] value from the NFS mode SID to cf_mode without masking to
07777. Apply the correct masking, same as in the read path. |
| Incorrect Default Permissions vulnerability in Apache Camel PQC component.
This issue affects Apache Camel: from 4.12.0 before 4.18.5, from 4.19.0 before 4.22.1.
When the component wrote generated key material to disk it did so with the permissions the process default umask produced, rather than restricting the file to its owner. On a host whose umask allows group or world read, the private key was therefore readable by other local accounts. The exposure is to a local party rather than to the remote sender that the Camel threat model treats as the primary adversary, which is why the severity is assessed low, but the consequence where it applies is complete: possession of the private key defeats every signature and key exchange the deployment performs with it.
Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. Users on the 4.22.x LTS releases stream should upgrade to 4.22.1. Key material is now written with owner-only permissions. For deployments that cannot upgrade immediately, place the key directory on a path only the service account can traverse, and tighten the process umask. Key material already written with permissive permissions should be treated as exposed and rotated. |
| Dell Alienware Command Center (AWCC), versions prior to 6.14.54.0, contain a Least Privilege Violation vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Elevation of Privilege and Denial of Service. |
| Mitigation bypass in the File Handling component. This vulnerability was fixed in Firefox ESR 153.5 and Thunderbird 153.5. |
| Hyland Desktop Host for Windows before 25.1.1 is vulnerable to local privilege escalation. This is caused by a privileged service running from the %PROGRAMDATA%\Hyland\DesktopHost\bin folder with weak permissions. A local user can exploit this to escalate privileges. |
| In the Linux kernel, the following vulnerability has been resolved:
powerpc: Do not restore KUAP in arch_exit_to_user_mode_prepare()
KUAP means kernel cannot touch user memory unless it explicitly is
enabled. In the kernel it should stay AMR_KUAP_BLOCKED. While returning
to userspace just before RFI, kernel should restore the user AMR value
back.
Looks like GENERIC_ENTRY might be treating arch_exit_to_user_mode_prepare()
as the last architecture step before returning to userspace.
commit bee25f97ad24 ("powerpc: Enable GENERIC_ENTRY feature")
therefore called kuap_user_restore() from that hook. But on PowerPC that
is too early. After irqentry_exit() / syscall_exit_to_user_mode() we
still run platform specific exit routines.
e.g. code snippets showing both exception handling and system call
handling as the callers of function arch_exit_to_user_mode_prepare()
which does kuap_user_restore(). The below path shows that calling
kuap_user_restore() is too early when called from
arch_exit_to_user_mode_prepare().
Exception handling in exceptions-64s.S
=======================================
bl CFUNC(do_page_fault)
..DEFINE_INTERRUPT_HANDLER_ASYNC(do_page_fault)
arch_interrupt_async_enter_prepare(regs);
state = irqentry_enter(regs);
instrumentation_begin();
irq_enter_rcu();
handler(regs);
nap_adjust_return(regs);
irq_exit_rcu();
instrumentation_end();
arch_interrupt_async_exit_prepare(regs);
irqentry_exit(regs, state); <<< too early
irqentry_exit_to_user_mode()
__exit_to_user_mode_prepare(regs, EXIT_TO_USER_MODE_WORK_IRQ);
arch_exit_to_user_mode_prepare(regs, ti_work); <<< too early
b interrupt_return_srr
.. bl CFUNC(interrupt_exit_user_prepare) <<< already calls kuap_user_restore
prep_irq_for_enabled_exit() retry can run kernel code with IRQs on. So
only when that routine is fully finished is when the user KUAP should be
fully restored which interrupt_exit_user_prepare() already takes care of
before returning.
Similarly for system call handling in interrupt_64.S
======================================================
bl CFUNC(system_call_exception)
.Lsyscall_exit:
addi r4,r1,STACK_INT_FRAME_REGS
li r5,0 /* !scv */
bl CFUNC(syscall_exit_prepare)
.. kuap_assert_locked();
syscall_exit_to_user_mode(regs); <<< too early
syscall_exit_to_user_mode_prepare(regs); <<< too early
kuap_user_restore(regs); <<< already calls
syscall_exit_prepare(), which can enable IRQs, replay a pending
interrupt, and only then rfi. Those functions already restore KUAP
immediately before rfi.
Note that if we restore the user AMR too early like in the current code
as shown from the code snippets above, then we get the following warning
when CONFIG_PPC_KUAP_DEBUG is enabled:

| Incorrect default permission in Samsung Flow prior to version 4.9.22.4 allows local attackers to launch an arbitrary activity with Samsung Flow privileges on the connected device. |
| Improper input validation in CreditCardRetrieveActivity of Samsung Checkout prior to version 5.1.03.1 allows local attackers to launch an arbitrary activity with Samsung Checkout privileges. |
| obsidian-tc is a governed, agent-ready Model Context Protocol server for Obsidian vaults. Prior to 1.3.1, undefined readPaths and writePaths settings allow all paths, strictReadDefault does not protect direct requests, and the .obsidian, .git, and .trash control directories are excluded only during enumeration. An authenticated caller can directly read sensitive files such as .obsidian/plugins/*/data.json, potentially exposing plugin API keys, Obsidian Sync passwords, and other in-vault data. Version 1.3.1 fixes the vulnerability by denying the control directories by default and enforcing strictReadDefault on direct request paths. |
| Incorrect default permissions in Windows Server Update Service allows an authorized attacker to elevate privileges locally. |
| When curl < 7.84.0 saves cookies, alt-svc and hsts data to local files, it makes the operation atomic by finalizing the operation with a rename from a temporary name to the final target file name.In that rename operation, it might accidentally *widen* the permissions for the target file, leaving the updated file accessible to more users than intended. |
| Vulnerability due to incorrect permissions in TSplus Remote Access shared login scripts. The autostart1.tscr files, located in the shared themes directory, allow users without sufficient privileges to write to them. A local attacker with a valid session on the terminal or remote desktop server could modify these files to execute arbitrary commands within another user’s security context when that user logs in using the same theme or operating mode. Depending on the affected user’s privileges, exploitation could allow lateral movement between users or privilege escalation. |
| sshd in OpenSSH 6.2 through 8.x before 8.8, when certain non-default configurations are used, allows privilege escalation because supplemental groups are not initialized as expected. Helper programs for AuthorizedKeysCommand and AuthorizedPrincipalsCommand may run with privileges associated with group memberships of the sshd process, if the configuration specifies running the command as a different user. |
| An issue was discovered in disable_priv_mode in shell.c in GNU Bash through 5.0 patch 11. By default, if Bash is run with its effective UID not equal to its real UID, it will drop privileges by setting its effective UID to its real UID. However, it does so incorrectly. On Linux and other systems that support "saved UID" functionality, the saved UID is not dropped. An attacker with command execution in the shell can use "enable -f" for runtime loading of a new builtin, which can be a shared object that calls setuid() and therefore regains privileges. However, binaries running with an effective UID of 0 are unaffected. |
| Privilege context switching error in Microsoft Office SharePoint allows an authorized attacker to elevate privileges over a network. |
| FreeRDP from 2.0.0 before 3.32.0 contains an insecure permission vulnerability in winpr-makecert that creates unencrypted private keys without owner-only file modes. Local users on multi-user Unix hosts can read world-readable key files or open PFX files protected by the hard-coded default password to steal private keys. |
| JupyterLab is an extensible environment for interactive and reproducible computing, based on the Jupyter Notebook Architecture. From 4.5.7 until 4.5.11 and 4.6.4, the markdownviewer:trust and notebook:trust command-link handlers use tracker.currentWidget to resolve the current Markdown viewer or notebook when the user answers rather than retaining the document whose command button was clicked. If another document becomes current while the prompt is open and the user chooses Trust, JupyterLab marks the second document trusted while leaving the clicked document untrusted. Later command buttons in the incorrectly trusted document run without a prompt, and trusting a notebook marks all cells trusted, saves unsaved edits, and persists the server signature to disk. Applications that bundle JupyterLab, including affected Notebook and JupyterLite releases, inherit the behavior. This issue is fixed in versions 4.5.11 and 4.6.4. |
| A container privilege escalation flaw was found in certain Ansible Automation Platform images. This issue arises from the /etc/passwd file being created with group-writable permissions during the build process. In certain conditions, an attacker who can execute commands within an affected container, even as a non-root user, can leverage their membership in the root group to modify the /etc/passwd file. This vulnerability allows an attacker to add a new user with any arbitrary UID, including UID 0, gaining full root privileges within the container. |
| goose from 1.28.0 before 1.44.0 contains an authorization bypass vulnerability that allows tools to run without user approval in Manual Approval mode because persisted read-only annotations are never cleared by update_goose_mode. After a session uses Smart Approval mode, prompt-injected calls to tools annotated readOnlyHint: true execute without prompting, bypassing the user's selected approval mode in PermissionInspector::inspect. |
