Description

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: add a check on the tid coming from the firmware ba_notif->tid is a firmware-controlled u8 that is used directly as an array index into tid_data[] without any validation. Add a bounds check against IWL_MAX_TID_COUNT before dereferencing the array.

CVE-2026-93425

Dokploy is a free, self-hostable Platform as a Service (PaaS). Prior to 0.29.13, the patch.readRepoDirectories tRPC procedure passes the user-controlled repoPath value from apps/dokploy/server/api/routers/patch.ts into a shell command in packages/server/src/services/patch-repo.ts without safe argument quoting. An authenticated organization member with service:read permission can inject shell metacharacters into repoPath and execute arbitrary commands through child_process.exec as root in the Dokploy container. The supplied service identifier is used only to resolve the server and does not constrain repoPath. Because the standard deployment mounts /var/run/docker.sock, container-root command execution can be used to control Docker and compromise the host and its managed applications. This issue is fixed in version 0.29.13.

CVE-2026-79766

Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. From 2.4.1 until 2.5.1, an authenticated Termix administrator can store attacker-controlled domain and email values through PATCH /users/acme-ssl-settings and trigger their interpolation into a certbot shell command through POST /users/acme-ssl-request. In src/backend/database/routes/acme-ssl-routes.ts, child_process.execSync invokes /bin/sh -c with those values only wrapped in double quotes, so shell metacharacters can execute arbitrary operating-system commands as the Termix backend process. Both HTTP webroot and DNS Cloudflare challenge modes are affected, and compromise exposes Termix databases, process secrets, stored credentials, and network reachability. This issue is fixed in version 2.5.1.

CVE-2026-93787

In the Linux kernel, the following vulnerability has been resolved: smb: client: bound dirent name against end of SMB response in cifs_filldir cifs_filldir() copies the entry name out of an SMB1 TRANS2_FIND_FIRST / FIND_NEXT response using a length (de.namelen) supplied by the server. The kmalloc'd SMB response buffer is bounded, but nothing checks that de.name + de.namelen still lies inside that buffer before the eventual filldir64() -> verify_dirent_name() -> memchr() reads namelen bytes. A hostile SMB1 server that returns an oversized FileNameLength in a directory entry therefore causes memchr() to read past the end of the response slab buffer. Reachable from any user who can list a directory on a CIFS mount served by an attacker-controlled server (getdents64() on the mounted directory): BUG: KASAN: slab-out-of-bounds in memchr+0x71/0x80 Read of size 1 at addr ffff88800e0640cc by task poc/115 Call Trace: dump_stack_lvl+0x64/0x80 print_report+0xce/0x620 kasan_report+0xec/0x120 memchr+0x71/0x80 filldir64+0x4c/0x6a0 cifs_filldir.constprop.0+0x9bb/0x1e00 cifs_readdir+0x2101/0x3380 iterate_dir+0x19c/0x520 __x64_sys_getdents64+0x126/0x210 do_syscall_64+0x107/0x5a0 entry_SYSCALL_64_after_hwframe+0x77/0x7f Pass the end-of-response pointer down to cifs_filldir() and reject entries whose name would extend past that boundary. This bug was discovered by Artiphishell's vTriage pipeline, which generated a userspace reproducer (an emulated hostile SMB1 server plus a getdents64() client) that reliably triggers the KASAN report on an unpatched kernel. The fix below was drafted with the Claude coding assistant; a userspace reproducer is available on request.
