CVE-2026-48982

pamusb provides hardware authentication for Linux using ordinary removable media. In versions prior to 0.9.2, when updating a one-time pad file, a temporary file is created using open without the OEXCL flag. Without OEXCL, the create operation is not atomic: two concurrent processes racing to...

CVE-2026-48981

pamusb provides hardware authentication for Linux using ordinary removable media. In versions prior to 0.9.2, pamusb calls xmlReadFile with flags=0 when loading the configuration file, allowing libxml2 to process external entity references XXE, potentially making outbound network connections or...

CVE-2026-48980 pam_usb: getenv() used in PAM context allows environment variable injection into local-check logic

pamusb provides hardware authentication for Linux using removable media. In versions prior to 0.9.2, getenv environment variables XRDPSESSION, DISPLAY and TMUX allow environment variable injection into local-check logic. These environment variables influence whether a current session is local or...

CVE-2026-48983 pam_usb: TOCTOU race condition in pad directory creation allows symlink substitution

pamusb provides hardware authentication for Linux using ordinary removable media. In versions prior to 0.9.2, a symlink race condition exists in per-device and per-user pad directory creation. pamusb uses a check-then-act pattern: it calls lstat to test for existence and then calls mkdir separate...

CVE-2026-48982 pam_usb: Missing O_EXCL on pad temp file creation allows concurrent update race

pamusb provides hardware authentication for Linux using ordinary removable media. In versions prior to 0.9.2, when updating a one-time pad file, a temporary file is created using open without the OEXCL flag. Without OEXCL, the create operation is not atomic: two concurrent processes racing to...

CVE-2026-48981 pam_usb: xmlReadFile flags=0 permits XXE network entity fetching in conf.c

pamusb provides hardware authentication for Linux using ordinary removable media. In versions prior to 0.9.2, pamusb calls xmlReadFile with flags=0 when loading the configuration file, allowing libxml2 to process external entity references XXE, potentially making outbound network connections or...

CVE-2026-48985 pam_usb: NULL Dereference Crash in pusb_is_loginctl_local when loginctl Returns Empty Remote Field

pamusb provides hardware authentication for Linux using ordinary removable media. In versions 0.9.1 and below, pusbisloginctllocal can cause a NULL dereference crash when parsing loginctl output. The function calls popen and reads the result; if the Remote field is only a newline, fgets succeeds...

CVE-2026-48986

CVE-2026-48986 affects pam_usb (Linux hardware authentication with removable media). In versions up to 0.9.1, the usb_get_process_parent_id() routine can cause an infinite loop DoS because it does not initialize *ppid on failure. In pusb_local_login(), the same variable is reused in a process-tre...

CVE-2026-48984 pam_usb: xfree() does not call explicit_bzero — sensitive cryptographic material may linger in freed heap

pamusb provides hardware authentication for Linux using ordinary removable media. In versions 0.9.1 and below, the xfree memory release helper in calls free without first zeroing the buffer contents, releasing heap-allocated buffers containing sensitive data — including one-time pad bytes read fr...

Siemens RuggedCom Rox Path Traversal (CVE-2025-6020)

A flaw was found in linux-pam. The module pamnamespace may use access user-controlled paths without proper protection, allowing local users to elevate their privileges to root via multiple symlink attacks and race conditions. This plugin only works with Tenable.ot. Please visit...

China-Linked Hackers Backdoored Linux Login Software to Hide for Nearly a Decade

Instead of hiding on the laptops and servers defenders watch most closely, a China-nexus group spent close to a decade hidden inside the Linux login system itself. Sygnia, which tracks the group as Velvet Ant , says it backdoored the PAM and OpenSSH components that decide who is allowed to sign i...

Devolutions Server < 2026.1.21.0 / 2026.2.4.0 < 2026.2.5.0 Multiple Vulnerabilities (DEVO-2026-0015)

The version of Devolutions Server installed on the remote host is prior to 2026.1.21.0 or 2026.2.4.0 prior to 2026.2.5.0. It is, therefore, affected by multiple vulnerabilities, including: - Improper neutralization of special elements in the built-in PAM provider password rotation templates in...
