      "title": "scsi: qla2xxx: Fix soft lockup polling continuation IOCB signature",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: qla2xxx: Fix soft lockup polling continuation IOCB signature\n\nqla27xx_copy_multiple_pkt() and qla27xx_copy_fpin_pkt() poll\nrsp_q->ring_ptr->signature for RESPONSE_PROCESSED (0xDEADDEAD) to decide\nwhether the next continuation IOCB has arrived, spinning on cpu_relax()\nwithout advancing the ring or decrementing the entry count while it has\nnot. response_t::signature lives at byte offset 60, but a continuation\nIOCB (sts_cont_entry_t / struct sts_cont_entry_ext) carries raw FC frame\npayload at that offset (data[56..59]). A received frame whose payload\nbytes happen to equal 0xDEADDEAD is therefore misread as \"not yet\narrived\", and the loop spins forever in interrupt/DPC context, causing a\nCPU soft lockup.\n\nThe poll is also unnecessary: callers of qla27xx_copy_multiple_pkt()\n(PT_LS4_UNSOL and the NVMe purls path) already gate on\nqla_chk_cont_iocb_avail(), which guarantees all entry_count IOCBs are\npresent before copying begins. The sibling helper\n__qla_copy_purex_to_buffer() already drops the signature poll and relies\non the entry_type == STATUS_CONT_TYPE guard instead.\n\nRemove the signature busy-wait from both helpers, keeping the entry_type\nguard, and gate the FPIN path with qla_chk_cont_iocb_avail() so it defers\nand re-processes on the next interrupt once all continuation IOCBs have\narrived, mirroring the ELS_AUTH_ELS and PT_LS4_UNSOL arms. With this the\nsignature field is never read on a continuation IOCB, eliminating the\npayload-aliasing lockup.",
