CVE-2026-89860
HighCVSS 8.8Summary
In the Linux kernel, the scsi qla2xxx driver's qla_nvme_fcp_abort() and qla_nvme_ls_abort() functions call INIT_WORK() before schedule_work(), which on repeated aborts of the same command can corrupt the workqueue list and lead to crashes or a looping worker.
Risk Assessment
May lead to kernel crash or system hang due to workqueue list corruption. Affects system stability and availability.
Recommendation
Update the Linux kernel to a version containing the fix that initializes abort_work once at command submission and leaves only schedule_work() in abort paths. Avoid repeated aborts of the same command.
Other vulnerabilities in Linux kernel
See all- CVE-2026-98163Unknown
A vulnerability was found in the Linux kernel's cgroup subsystem, involving iteration over dying tasks with a zero reference count. This leads to a race condition where the iterator may access a task after it has been freed, resulting in a use-after-free.
- CVE-2026-98162Unknown
In the Linux kernel, the smb2_tree_connect() function of the SMB server (ksmbd) leaks a tree connection. When ksmbd_iov_pin_rsp() fails, the newly created tree connection is not disconnected, leading to a resource leak.
- CVE-2026-98161Unknown
In the Linux kernel, the nvdimm (pmem) pmem_submit_bio() function records a REQ_PREFLUSH error but continues to copy bio data and can later overwrite the error with a successful REQ_FUA flush. This allows data writes to run after a failed preflush and can complete the bio successfully despite the failed ordering barrier.
- CVE-2026-98160Unknown
In the Linux kernel, the staging rtl8723bs driver's rtw_sdio_if1_init() function frees padapter->HalData with kfree(), even though it was allocated via vzalloc(). Using kfree() to release a vmalloc-backed buffer can lead to memory corruption.
- CVE-2026-100079Unknown
In the Linux kernel, the USB Type-C (ucsi) subsystem's ucsi_register() creates per-instance debugfs entries, but ucsi_unregister() keeps them until ucsi_destroy(). Drivers like ucsi_glink that unregister/register the same UCSI instance across remoteproc restart then try to create an already existing debugfs directory.
- CVE-2026-100078Unknown
In the Linux kernel, the iwlwifi (mei) driver's iwl_mei_write_cyclic_buf() function receives an incorrect first argument — the q_head pointer is passed instead of cldev. The bug has been fixed.
- CVE-2026-100077Unknown
In the Linux kernel, the drm/msm driver does not safely retire a hung submit before GPU recovery completes. Retiring the submit triggers BO free, which can result in GPU pagefaults since the GPU may be actively accessing those BOs.
- CVE-2026-100074Unknown
In the Linux kernel, a bug was fixed where the BPF_REFCOUNT field was not marked as unique, although it should be. The fix addresses this oversight.
- CVE-2026-100073Unknown
In the Linux kernel, a bug in the ext4 filesystem related to transaction overflow during writeback was fixed. A previous fix was too eager in reducing reserved transaction credits, leading to insufficient reservation in some corner cases. The fix uses ext4_meta_trans_blocks() for a correct upper bound estimate.
- CVE-2026-100072Unknown
In the Linux kernel, a problem in the ACPI subsystem was fixed where the use of acpi_get_first_physical_node() in acpi_platform_fill_resource() and acpi_create_platform_device() was unsafe because the returned device could be freed at any time. The fix replaces it with acpi_bus_get_primary_device() and adjusts the code to call it only once.
Original NVD description (English source)
In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Initialize NVMe abort_work once at submission qla_nvme_fcp_abort() and qla_nvme_ls_abort() ran INIT_WORK() on priv->abort_work immediately before schedule_work(). INIT_WORK() reinitializes the work_struct, resetting its list head and clearing the pending bit. If an abort is issued more than once for the same command (for example, concurrent transport teardown and a timeout-driven abort), the second INIT_WORK() reinitializes a work item that is already queued, which can corrupt the workqueue list and lead to crashes or a looping worker. Initialize priv->abort_work once at command submission, next to the existing per-command spin_lock_init(&priv->cmd_lock), and leave only schedule_work() in the abort paths. schedule_work() already does nothing when the work item is still pending, so a repeated abort no longer disturbs an in-flight work item. The command is not returned to the transport until the final kref_put()/release callback runs after abort_work has completed, so the work item is idle before priv is reused and the single submission-time INIT_WORK() is safe.
