Overview
Description
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: validate owner of durable handle on reconnect
Currently, ksmbd does not verify if the user attempting to reconnect
to a durable handle is the same user who originally opened the file.
This allows any authenticated user to hijack an orphaned durable handle
by predicting or brute-forcing the persistent ID.
According to MS-SMB2, the server MUST verify that the SecurityContext
of the reconnect request matches the SecurityContext associated with
the existing open.
Add a durable_owner structure to ksmbd_file to store the original opener's
UID, GID, and account name. and catpure the owner information when a file
handle becomes orphaned. and implementing ksmbd_vfs_compare_durable_owner()
to validate the identity of the requester during SMB2_CREATE (DHnC).

Davide Ornaghi and Giuseppe Caruso found a very interesting bug in #Linux's in-kernel Samba3 server from 6.12 to 6.19.x. Essentially, from the commit message and #CVE description:
> Currently, ksmbd does not verify if the user attempting to reconnect to a durable handle is the same user who originally opened the file. This allows any authenticated user to hijack an orphaned durable handle by predicting or brute-forcing the persistent ID.
Very interesting stuff! The kernel let's users resume their connection to an open file even after WiFi drops (durable handle), and a bug in this code let another authenticated user become this WiFi-dropped user, letting the hijacker access all files.

CVE-2026-31717
Overview
Description
In the Linux kernel, the following vulnerability has been resolved:
crypto: caam - fix overflow on long hmac keys
When a key longer than block size is supplied, it is copied and then
hashed into the real key. The memory allocated for the copy needs to
be rounded to DMA cache alignment, as otherwise the hashed key may
corrupt neighbouring memory.
The copying is performed using kmemdup, however this leads to an overflow:
reading more bytes (aligned_len - keylen) from the keylen source buffer.
Fix this by replacing kmemdup with kmalloc, followed by memcpy.

Description
DrayTek Vigor 2960 firmware versions prior to 1.5.1.4 contain an OS command injection vulnerability in the CGI login handler that allows unauthenticated remote attackers to execute arbitrary commands by injecting shell metacharacters into the formpassword parameter. Attackers can exploit unsanitized input passed to the otp_check.sh script to achieve remote code execution with web server privileges. Exploitation requires knowledge of a valid username and that the target account has MOTP authentication enabled.

Description
Claude Code is an agentic coding tool. Prior to version 2.1.64, Claude Code's sandbox did not prevent sandboxed processes from creating symlinks pointing to locations outside the workspace. When Claude Code subsequently wrote to a path within such a symlink, its unsandboxed process followed the symlink and wrote to the target location outside the workspace without prompting the user for confirmation. This allowed a sandbox escape where neither the sandboxed command nor the unsandboxed app could independently write outside the workspace, but their combination could write to arbitrary locations, potentially leading to code execution outside the sandbox. Reliably exploiting this required the ability to add untrusted content into a Claude Code context window to trigger sandboxed code execution via prompt injection. Users on standard Claude Code auto-update have received this fix automatically. Users performing manual updates are advised to update to version 2.1.64 or later.

Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, toFormData recursively walks nested objects with no depth limit, so a deeply nested value passed as request data crashes the Node.js process with a RangeError. This vulnerability is fixed in 1.15.1 and 0.31.1.

Description
Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. Prior to version 2.1.0, all Docker container management endpoints in Termix interpolate the containerId URL path parameter and WebSocket message field directly into shell commands executed via ssh2.Client.exec() on remote managed servers without any sanitization or validation. An authenticated attacker can inject arbitrary OS commands by crafting a malicious container ID, achieving Remote Code Execution on any managed server. This issue has been patched in version 2.1.0.
