More Linux LPEs

Hark the age of the Linux LPE has arrived. This week’s release follows up on recent work bringing new Linux LPEs to Metasploit users. Copy Fail seemed to have kicked off a trend of similar bugs and hot on its heels is Dirty Frag. Dirty Frag is actually two vulnerabilities in a trenchcoat, individually identified as CVE-2026-43284 and CVE-2026-43500. Each is exploitable individually and comes with a new Metasploit module.

Bugs fixed (4)

• #21390 from zeroSteiner - This refines our smb_to_ldap relay attack reporting by demoting anonymous authentication messages from print_good to print_status, reflecting that anonymous sessions do not grant additional privileges. It also skips the #on_relay_success callback for these sessions to prevent modules from needlessly acting on unprivileged access.
• #21443 from jheysel-r7 - This bumps the Metasploit-credentials gem to address an issue in how Kerberos hashes were being handled.
• #21485 from adfoster-r7 - Fixes MCP server test failure.
• #21487 from adfoster-r7 - Updates to a newer version of RubyZip to support Zip files larger than 4GB.
