Loading vulnerability…
CVE-2026-23110 is a race-condition vulnerability in the Linux kernel SCSI core's command completion and failure accounting. In scsi_dec_host_busy(), the write clearing SCMD_STATE_INFLIGHT can be reordered with reads in scsi_host_busy(), allowing other CPUs to observe an elevated busy-command count. Separately, scsi_eh_inc_host_failed() counts busy commands before incrementing host_failed and can race with a final command completion. Both races can prevent the error-handler wake-up condition from being observed, leaving I/O through the affected SCSI host stuck because error recovery cannot advance.

A Linux kernel SCSI-core vulnerability involving memory-ordering and command-completion race conditions. These races can prevent the SCSI error handler from waking, leaving host I/O stuck and impairing availability. The reference assigns a CVSS v3 base score of 4.7, with local access, low privileges, and high attack complexity.
A Linux kernel SCSI core vulnerability involving memory-ordering and command-completion races in scsi_dec_host_busy() and scsi_eh_inc_host_failed(). These races can prevent the error handler from waking, causing SCSI host I/O to stall and affecting availability. The advisory assigns a CVSS v3 base score of 4.7, with local access, low privileges, and high attack complexity. It recommends updating Echo's linux package and related packages to version 6.1.162-1 or later.
A Linux kernel SCSI core race-condition issue involving final completions and the error handler, affecting Rocky Linux 10.2 kernel packages in CIQ advisory crlsa-2026_45114.
A Linux kernel SCSI core vulnerability involving error-handler wake-up behavior when final completions race against each other.
