  1. CVE-2026-16615 6.8 Moyenne

    GNOME librest · Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 10.0 Extended Update Support

    A flaw was found in librest. The PKCE implementation for OAuth authorization uses the GRand function from the GLib API, a cryptographically insecure pseudo-random number generator. Because the generated "code verifier" lacks sufficient cryptographic entropy, a malicious actor can reverse-engineer the pseudo-random number generator (PRNG) seed to predict or reconstruct the code verifier string, allowing an attacker to bypass PKCE protections and successfully impersonate the client during the OAuth 2.0 authorization flow.

  2. CVE-2026-16607 7.8 Élevée

    Fujitsu Linux openFT · Fujitsu Oracle Solaris openFT

    A vulnerability in Fujitsu Software Linux openFT and Fujitsu Software Oracle Solaris openFT before version 12.1D00 allows for local privilege escalation to root of an already authenticated user on GNU/Linux or Oracle Solaris. The Fsas Technologies PSIRT obtained that intelligence internally and covers the CVE beyond its CNA scope under existing agreement with Fujitsu Germany.

  3. CVE-2026-16606 9.8 Critique

    Fujitsu Linux openFT · Fujitsu Oracle Solaris openFT

    A vulnerability in Fujitsu Software Linux openFT and Fujitsu Software Oracle Solaris openFT before version 12.1D00 allows for unauthenticated remote code execution (pre-auth RCE) on GNU/Linux or Oracle Solaris. The Fsas Technologies PSIRT obtained that intelligence internally and covers the CVE beyond its CNA scope under existing agreement with Fujitsu Germany.

  4. CVE-2026-50251 5.3 Moyenne

    NLnet Labs Unbound · Nlnetlabs unbound

    In NLnet Labs Unbound up to and including version 1.25.1, when 'unwanted-reply-threshold' is enabled (set to any value greater than zero), glue records of 0.0.0.0/::0 can short-circuit Unbound, on systems that can direct such traffic, by issuing DNS queries and receiving seemingly unwanted replies since the remote IP does not match the original source IP of 0.0.0.0/::0. This behavior keeps on looping for the glue records and pushing the counter to the configured 'unwanted-reply-threshold' that triggers a defensive cache clear. A malicious actor who controls a delegation that returns in-bailiwick glue of 0.0.0.0/::0 can drive the counter to the limit of 'unwanted-reply-threshold' to the threshold and trigger a cache clean of the message and rrset caches; at will, indefinitely, without sending a single spoofed packet. The iterator uses the 0.0.0.0/::0 glue, and a system that can route this (e.g., Linux kernel routes the datagram over loopback), Unbound's own listener answers from 127.0.0.1. Because of the mismatch of 0.0.0.0 and 127.0.0.1, in this example, Unbound accounts the reply as an unwanted (probably spoofed) answer. The counter resets to zero on every cache flush, so the attack loops forever.

  5. CVE-2026-16560 5.3 Moyenne

    Red Hat Directory Server 11 · Red Hat Directory Server 12 · Red Hat Directory Server 13 · Red Hat Enterprise Linux 10

    A heap-buffer-overflow flaw was found in Directory Server (389-ds-base). When a DN contains a legacy-quoted value, the server won't close the heap allocation allowing another call to refer to the same memory pointer causing a denial of service or an arbitrary memory write operation.

  6. CVE-2026-65590 9.8 Critique

    n8n-io n8n · N8n n8n

    n8n before 2.29.8 and 2.30.x before 2.30.1 does not enforce shell sandbox restrictions on Linux and Windows in the @n8n/computer-use package (sandboxing was applied only on macOS). Shell commands executed by the tool run without any filesystem or network restrictions, allowing unrestricted access to the host filesystem and network from within the computer-use agent process. This issue only affects deployments where the @n8n/computer-use package is explicitly installed and running; standard n8n installations are not affected.

  7. CVE-2026-16473 4.3 Moyenne

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9

    A flaw was found in the sbc library (BlueZ SBC codec). An off-by-one error in the SBC frame decoder allows a crafted audio payload to trigger a one-byte heap out-of-bounds read. This could allow an adjacent attacker streaming Bluetooth audio to read a single byte of adjacent heap memory.

  8. CVE-2026-16517 2.9 Faible

    Red Hat Enterprise Linux 10 · Red Hat Hardened Images · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7

    A signed integer overflow vulnerability was found in libarchive's ZIP writer. In the archive_write_zip_header function in archive_write_set_format_zip.c, when ZIP encryption is enabled and the entry file size is close to INT64_MAX, the addition of the encryption overhead to the entry size overflows int64_t, resulting in undefined behavior. This could lead to incorrect Zip64 extension decisions or potential memory corruption.

  9. CVE-2026-16422 7.5 Élevée

    Google Chrome

    Insufficient validation of untrusted input in Certificate in Google Chrome on Linux prior to 150.0.7871.182 allowed an attacker in a privileged network position to perform domain spoofing via malicious network traffic. (Chromium security severity: High)
