CVE-2026-72082
In the Linux kernel, the following vulnerability has been resolved: scsi: elx: efct: Fix refcount leak in efct_hw_io_abort() When efct_hw_reqtag_alloc() fails in efct_hw_io_abort(), the error path returns -ENOSPC without releasing the reference obtained via kref_get_unless_zero() earlier in the function. All other error paths correctly drop the reference. This causes a permanent reference leak on the io_to_abort object. Additionally, the abort_in_progress flag is left set to true on this path, which means future abort attempts for the same I/O will immediately return -EINPROGRESS even though the abort was never submitted, effectively blocking recovery. Fix this by adding the missing kref_put() call and reset abort_in_progress to false, matching the cleanup done in the efct_hw_wq_write() failure path below.

Affected products and versions
NVD has not supplied machine-readable vulnerable CPE product/version entries for this CVE. This is an information gap, not proof that no products are affected. Check the vendor advisory references below.
Remediation & validation
- Identify exposure by comparing the affected product and version ranges with your asset inventory, SBOM and externally exposed services.
- Review the linked vendor security advisory or patch notes. Upgrade to a vendor-confirmed fixed release; do not infer a fixed version from the CVE description.
- Until patched, consider restricting network access or disabling the affected feature where operationally safe. These are temporary controls, not a substitute for a vendor fix.
- Validate the remediation with a version check and vulnerability rescan, then retain change evidence.
No fixed version is displayed unless it is explicitly established by a vendor advisory. Follow the vendor's release notes for exact product and branch applicability.
