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...

CVE-2026-89844

CVE-2026-89844 is a locking race in the Linux kernel qla2xxx SCSI driver. In qla24xx_report_id_acquisition(), the format-1 path drops vport_slock after taking the vport reference and then calls qla_update_host_map() without holding the lock. That function mutates the ha->host_map btree via btr...

CVE-2026-89843

CVE-2026-89843 affects the Linux kernel scsi: qla2xxx driver (QLogic). Several bsg handlers use an uninitialized 256-byte on-stack buffer (uint8_t bsg[DMA_POOL_SIZE]) that is filled via sg_copy_to_buffer(), which copies only the user-supplied request length. When the request is shorter than the s...

CVE-2026-89842

CVE-2026-89842 affects the Linux kernel's qla2xxx driver (QLogic Fibre Channel HBA). When firmware is not started (fw_started clear), qla_nvme_xmt_ls_rsp() unconditionally emits a NVMe LS reject IOCB via the out: path, ringing the firmware doorbell and writing to the request queue in-pointer regi...

CVE-2026-89841

CVE-2026-89841 affects the f2fs filesystem in the Linux kernel . The flaw resides in redirty_blocks(), where a do/while loop introduced by commit 5951fee46bef causes an extra iteration when read_cache_folio() fails before any folio is pinned. If readahead has already populated the failed folio in...

CVE-2026-89840

CVE-2026-89840 is a vulnerability in the Linux kernel's f2fs filesystem affecting the F2FS_IOC_MOVE_RANGE ioctl. The ioctl validates the source range but fails to check the destination end before updating i_size. When a source hole is present, __clone_blkaddrs() skips NULL_ADDR entries and return...

CVE-2026-89839

CVE-2026-89839 affects the f2fs filesystem in the Linux kernel. The function f2fs_xattr_advise_set() calls inode_owner_or_capable() with &nop_mnt_idmap instead of the idmap that the VFS passes to the ->set() handler when checking ownership for the "system.advise" xattr . On idmapped mounts , t...

CVE-2026-89838

CVE-2026-89838 affects the Linux kernel's F2FS filesystem . The i_name buffer for recovery filenames is not NUL-terminated, yet recover_inode() and recover_dentry() print it with %s. For a 255-byte filename , recovery logging can read past i_name into subsequent raw inode fields. The fix bounds t...
