kernel: scsi: core: Wake up the error handler when final completions race against each other

Race condition vulnerabilities were found in the Linux kernel's SCSI error handler wake-up logic. Memory ordering issues in scsidechostbusy and ordering problems in scsiehinchostfailed can cause the SCSI error handler to never wake up when command completions race against each other. This leaves...

CVE-2026-64003

In the Linux kernel, the following vulnerability has been resolved: scsi: core: Run queues for all non-SDEVDEL devices from scsirunhostqueues While a SCSI host is in a recovery state, scsimqrequeuecmd will not set the requeue list for a requeued command to be kicked in the future. The expectation...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: scsi: core: There is a race condition where the error handler is only awakened when the last running command completes or times out. This race condition can cause the SCSI layer to fail to awaken the error handler, resulting i...

CVE-2026-53186

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA SCSI RDMA Protocol SRP component. A malicious or compromised SRP target on the InfiniBand/RoCE fabric can exploit this vulnerability by sending a specially crafted SRP response with an excessively large data length. This can...

USN-8412-1 qemu vulnerabilities

Felipe Franciosi, Raphael Norwitz, and Peter Turschmid discovered that the iSCSI block driver in QEMU incorrectly handled certain responses from an iSCSI server. A remote attacker could possibly use this issue to cause QEMU to crash, resulting in a denial of service, or possibly execute arbitrary...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: scsi: hisisas: Freeing irq vectors in order for v3 HW If the driver probe fails to request the channel IRQ or fatal IRQ, the driver will free the IRQ vectors before freeing the IRQs in freeirq. This will cause a kernel BUG like...

In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Prevent lpfcdebugfslockstatwrite buffer overflow A static code analysis tool identified the possibility of buffer overflow when using copyfromuser for a debugfs entry. Currently, it is possible that copyfromuser copie...

Astra Linux – Vulnerability in Qemu

A NULL pointer dereference flaw was discovered in the SCSI emulation support of QEMU in versions prior to 6.0.0. This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of service. The greatest threat from this vulnerability is to system availability...

CVE-2026-43054

In the Linux kernel, the following vulnerability has been resolved: scsi: target: tcmloop: Drain commands in targetreset handler tcmlooptargetreset violates the SCSI EH contract: it returns SUCCESS without draining any in-flight commands. The SCSI EH documentation scsieh.rst requires that when a...

CVE-2025-68782

In the Linux kernel, the following vulnerability has been resolved: scsi: target: Reset ttaskcdb pointer in error case If allocation of cmd-ttaskcdb fails, it remains NULL but is later dereferenced in the 'err' path. In case of error, reset NULL ttaskcdb value to point at the default fixed-size...

CVE-2025-68371

CVE-2025-68371 relates to the Linux kernel SCSI smartpqi driver. A race between the abort handler that schedules a LUN reset and device removal via sdev_destroy() could cause the LUN reset to run after the device was removed, leading to use‑after‑free and access to freed resources. The fix, as do...
