Summary

Heap-based buffer overflow in the iscsi_add_notunderstood_response function in drivers/target/iscsi/iscsi_target_parameters.c in the iSCSI target subsystem in the Linux kernel through 3.9.4 allows remote attackers to cause a denial of service (memory corruption and OOPS) or possibly execute arbitrary code via a long key that is not properly handled during construction of an error-response packet.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
