USN-8736-2: Perl vulnerabilities

Ubuntu issued USN-8736-2 fixing two Perl regex flaws that could cause out-of-bounds heap access, denial of service, or security bypass on 24.04 LTS.

USN-8736-2 backports the Perl fixes from USN-8736-1 to Ubuntu 24.04 LTS. CVE-2026-15534 involves out-of-bounds heap reads or writes when regular expressions handle large inputs, potentially causing denial of service or arbitrary code execution. CVE-2026-19487 causes incorrect regex matching with alternative branches, allowing security restrictions to be bypassed.

Sandworm-Linked UAC-0145 Uses Fake Job Interviews to Push VPN That Can Run Commands

CERT-UA says Sandworm-linked UAC-0145 poses as recruiters in fake job interviews to deliver a trojanized WireGuard VPN that runs attacker commands on victims' hosts.

CERT-UA attributes the campaign, ongoing since May 2026, to UAC-0145, a subgroup within GRU-affiliated Sandworm (APT44). Posing as HR staff of firms like ATLAS Business Group and Sopra Steria Bulgaria, attackers lure Ukrainian IT specialists into Zoom interviews, then share failing WireGuard configs and push a custom SopraVPN client from SourceForge. The modified WireGuard build supports a non-standard SymmetricKey option holding AES-256-GCM-encrypted PowerShell, decrypted with the decoded PrivateKey and executed via runScriptCommand. A scheduled task then downloads a second-stage payload on Windows, while the Linux variant fetches it via cURL.

Srsly Risky Biz: Data Theft Extortion Is Booming! Hooray!

Google's Threat Intelligence Group reports data theft extortion is surging, with Silent Ransom extracting $10M and $18M from two law firms and BlackFile taking $10M.

Risky Business News, citing Google Threat Intelligence Group (GTIG), reports that cybercriminals are shifting from encrypting ransomware to data theft extortion. Law firms Goodwin Procter and WilmerHale paid Silent Ransom (Luna Moth) ransoms of $10 million and $18 million respectively; GTIG says the group often completes contact-to-extortion in a single day, now sometimes compromising systems in person posing as IT staff. BlackFile, now calling itself Redact, used high-volume vishing to steal credentials and pivot through OneDrive, SharePoint and other SaaS apps, collecting more than $10 million between February and mid-May with an average ransom of $750,000, including attempted attacks on Wall Street hedge funds and private equity firms. The piece argues governments should keep pressure on encrypting ransomware gangs while lower-impact extortion absorbs criminal energy.

Zero Day Initiative — CVE-2026-33824: Remote Code Execution in Windows ...

ZDI details CVE-2026-33824, a double-free in Windows IKEv2 fragment reassembly enabling unauthenticated remote code execution as SYSTEM on Windows.

Zero Day Initiative published technical analysis of CVE-2026-33824, a double-free in the Windows IKE Extension (ikeext.dll) caused by improper ownership handling of a heap blob pointer during IKEv2 fragment reassembly in IkeReinjectReassembledPacket(). A remote unauthenticated attacker can send a crafted IKE_SA_INIT message with a Security Realm Vendor ID followed by fragmented IKE_AUTH payloads to trigger the double free. Successful exploitation could yield arbitrary code execution under the IKEEXT service context (SYSTEM). ZDI also provided IDS detection guidance correlating the two-packet sequence on UDP ports 500 and 4500.

Researcher Hyunwoo Kim disclosed CVE-2026-89775, a guest-to-host escape in KVM/arm64, after the embargo agreed with linux-distros maintainers expired. The root cause is a type truncation of the stage-1 walk level that makes a size computation return 0, the value meaning 'size unknown'. The VNCR pseudo-TLB invalidation path then interprets that 0 as a valid value on ARM64 hosts where nested virtualization is enabled.
