Loading vulnerability…
CVE-2026-63887 is a heap-based out-of-bounds write in the Linux kernel SCSI target iSCSI implementation. During iSCSI login text negotiation, iscsi_encode_text_output() serializes key/value response records into a fixed 8192-byte response buffer but, prior to the fix, its formatting operations did not validate remaining capacity. A single Login PDU may contain numerous minimal unknown key/value pairs; each can be expanded into a larger NotUnderstood response record. The resulting encoded response can exceed the buffer by approximately 24 KiB, corrupting adjacent kmalloc-8k slab memory.
