CVE-2026-89865

CVE-2026-89865 affects the Linux kernel's qla2xxx SCSI driver (QLogic). The FRU and I2C bsg handlers stage transfers in a 256-byte DMA bounce buffer allocated via dma_pool_alloc() , which does not zero the memory. Only a small leading prefix is initialized (e.g., 36 bytes for a FRU version, 1 byt...

CVE-2026-89863

CVE-2026-89863 is a NULL pointer dereference in the Linux kernel's qla2xxx SCSI driver, specifically in the EDIF (Extended Data Integrity Field) subsystem. The function qla_chk_edif_rx_sa_delete_pending() obtains a SCSI command pointer via GET_CMD_SP(sp) and immediately dereferences cmd->sc_da...

CVE-2026-89862

CVE-2026-89862 affects the Linux kernel in the scsi: qla2xxx driver. The function qla28xx_validate_flash_image() returns QLA_SUCCESS (0) unconditionally, signaling to the FC BSG transport that the driver owns and will complete the request. However, bsg_job_done() is guarded by an if (!rval) check...

CVE-2026-89860

CVE-2026-89860 affects the qla2xxx (QLogic) SCSI driver in the Linux kernel , specifically its NVMe abort handling. The root cause is that qla_nvme_fcp_abort() and qla_nvme_ls_abort() called INIT_WORK() on priv->abort_work immediately before schedule_work(). When an abort is issued more than o...

CVE-2026-89861

A use-after-free vulnerability exists in the Linux kernel's qla2xxx SCSI driver, specifically in qla24xx_report_id_acquisition(). In the format 1 path, the virtual port is located on ha->vp_list while holding vport_slock, but the lock is dropped before the vport is subsequently used by qla_upd...

CVE-2026-89859

This Linux kernel vulnerability affects the scsi: qla2xxx (QLogic Fibre Channel HBA) driver. In qla2x00_do_dport_diagnostics(), the qla_dport_diag response buffer is allocated with kmalloc_obj() (non-zeroing), but only a subset of the buffer is populated by the user request. The options and unuse...

CVE-2026-89858

CVE-2026-89858 affects the Linux kernel's qla2xxx SCSI driver in the function qla2x00_update_fru_versions(). A user-supplied BSG request is copied into a fixed 256-byte stack buffer , and the loop iteration count (list->count) is taken directly from user input with no upper bound , while only ...

CVE-2026-89857

CVE-2026-89857 affects the Linux kernel qla2xxx SCSI driver, specifically the NVMe-FC path. The root cause is a missing lock : qla_nvme_ls_reject_iocb() allocates and advances the request ring assuming the hardware lock is held, but two callers—qla_nvme_xmt_ls_rsp() (NVMe-FC transport callback er...

CVE-2026-89856

A vulnerability in the Linux kernel qla2xxx SCSI driver arises from a type-width mismatch: ha->msix_count is u16 while derived queue counts (max_req_queues, max_rsp_queues, max_qpairs) are u8 . A device (physical or hot-plugged) advertising 257 MSI-X vectors causes msix_count - 1 to equal 256,...

CVE-2026-89855

CVE-2026-89855 affects the qla2xxx SCSI driver in the Linux kernel. The "update cache versions without reset" sysfs reset operation (0x20261) calls get_flash_version() to read hardware flash registers without holding ha->optrom_mutex , allowing it to interleave with concurrent VPD or optrom fl...

CVE-2026-89853

CVE-2026-89853 is a use-after-free in the Linux kernel's qla2xxx SCSI driver. The function qla2x00_free_fce_trace() freed the FCE DMA buffer while holding only fce_mutex, but firmware-dump consumers (qla27xx_fwdt_entry_t264(), qla25xx_copy_fce()) read that buffer under hardware_lock without acqui...

CVE-2026-89854

CVE-2026-89854 is a use-after-free in the Linux kernel's qla2xxx SCSI driver . During host teardown, qla84xx_put_chip() frees the ha->cs84xx chip structure without clearing the pointer, and it runs before scsi_remove_host() removes the 84xx_fw_version sysfs attribute. A concurrent read of that...

CVE-2026-89852

In the Linux kernel 's qla2xxx SCSI driver, the mbx_cmd_t struct is allocated on the stack but left uninitialized. When qla2x00_mailbox_command() hits an early-return path (PCI permanent failure, device failed, EEH busy, ISP abort pending, mailbox access timeout, or purge mbox), it returns withou...

CVE-2026-89851

A bug in the Linux kernel scsi: qla2xxx driver (QLogic SCSI) affected the FCE trace enable write handler in debugfs (qla2x00_dfs_fce_write()). The function called kstrtoul() with a NULL result pointer , so a successful parse would dereference NULL and trigger a kernel oops . Additionally, the int...

CVE-2026-89850

CVE-2026-89850 affects the Linux kernel qla2xxx SCSI driver . In qla2x00_fw_state_show(), when the chip is down or EEH is busy, rval is set to QLA_FUNCTION_FAILED and execution jumps to the out: label, which then re-issues qla2x00_get_firmware_state() because rval != QLA_SUCCESS. This defeats the...

CVE-2026-89849

This vulnerability affects the qla2xxx SCSI driver in the Linux kernel . The root cause is a logic flaw in qla2x00_status_entry(): after filtering out certain SRB types, the code falls through to a SCSI fast path that unconditionally assumes the command is an SRB_SCSI_CMD. Because the srb union o...

CVE-2026-89848

A use-after-free in the Linux kernel qla2xxx SCSI driver occurs during queue-pair teardown. qla2xxx_delete_qpair() frees the request queue before releasing the response-queue MSI-X interrupt; in that window a late response interrupt can fire and dereference the freed rsp->req pointer via qla24...

CVE-2026-89847

CVE-2026-89847 is a use-after-free in the Linux kernel qla2xxx SCSI driver . When qla24xx_async_abort_cmd() fails in qla2x00_async_iocb_timeout(), both the SRB_LOGIN_CMD and SRB_CTRL_VP paths call sp->done() unconditionally without verifying the SRB was actually found and removed from outstand...

CVE-2026-89846

CVE-2026-89846 is a critical out-of-bounds read in the Linux kernel's qla2xxx SCSI driver. In qla2x00_status_entry(), the FWI2 status path subtracts rsp_info_len (a 32-bit value from the target's FCP response) from par_sense_len (the IOCB data area size: 28 bytes for 24xx, 60 bytes for 29xx) with...

CVE-2026-89845

CVE-2026-89845 affects the Linux kernel qla2xxx SCSI driver (QLogic HBA). The function qla2x00_error_entry() reads ha->req_q_map[que] twice — once for a NULL check and again when assigning the pointer. During queue teardown, qla25xx_free_req_que() clears the slot to NULL under mq_lock, but the...
