CVE-2026-77587

A flaw was found in Tor. A malicious exit node could exploit a use-after-free vulnerability in the handling of conflux objects. This occurs when a recovery leg attempts to revive a conflux set whose last linked leg has already been closed. Successful exploitation of this flaw could lead to a clie...

SUSE CVE-2026-77587

Tor before 0.4.9.11 is prone to a use-after-free and potential double free of a conflux object when a recovery leg revives a conflux set whose last linked leg has already been closed. A malicious exit node could use this to crash a client. This is TROVE-2026-026...

tor before 0.4.9.9 was prone to a NULL write after free when sending a CONFLUXSWITCH cell fails. The return value of relaysendcommandfromedge was ignored, so a send failure which calls circuitmarkforclose and removes the leg via cfxdelleg would go undetected, causing the caller to write to the...

CVE-2026-77584

Tor before 0.4.9.10 did not reject a CONFLUXLINK cell that arrives on a circuit which already has attached streams. A malicious client could send a RELAYCOMMANDBEGIN before the CONFLUXLINK on the same circuit, attaching an exit stream that would later end up orphan leaving a dangling circuit...

CVE-2026-77641

tor versions before 0.4.9.9 are affected by a NULL write after free in the CONFLUX protocol handling. When sending a CONFLUX_SWITCH cell fails, the return value of relay_send_command_from_edge() is ignored. The failed send triggers circuit_mark_for_close() and removes the circuit leg via cfx_del_...
