CVE-2026-46105

CVE-2026-46105 affects the Linux kernel mpt3sas SCSI driver. The driver allocates a fixed 4K PRP list buffer, which caps the maximum NVMe I/O transfer size at 2 MiB. The HBA firmware reports NVMe MDTS, but the mismatch with the 2 MiB limit can lead to oversized I/O requests and potentially a kern...

CVE-2026-46105

In the Linux kernel, the following vulnerability has been resolved: scsi: mpt3sas: Limit NVMe request size to 2 MiB The HBA firmware reports NVMe MDTS values based on the underlying drive capability. However, because the driver allocates a fixed 4K buffer for the PRP list, accommodating at most 5...

CVE-2026-45855

A flaw was found in the Linux kernel's libata-scsi component. This vulnerability allows for a denial of service DoS where non-Native Command Queuing NCQ commands can experience significant delays or complete starvation. This occurs when non-NCQ commands are issued while NCQ commands are actively...

CVE-2026-45857

A flaw was found in the Linux kernel's scsi: csiostor module. This null pointer dereference vulnerability occurs in an error handling path. A local attacker could exploit this to cause a system crash, leading to a Denial of Service DoS. Mitigation To prevent exploitation, the csiostor kernel modu...

In the Linux kernel, the following vulnerability has been resolved: ata: libata-scsi: avoid Non-NCQ command starvation When a non-NCQ command is issued while NCQ commands are being executed, atascsiqcissue indicates to the SCSI layer that the command issuing should be deferred by returning...

SUSE CVE-2026-45857

In the Linux kernel, the following vulnerability has been resolved: scsi: csiostor: Fix dereference of null pointer rn The error exit path when rn is NULL ends up deferencing the null pointer rn via the use of the macro CSIOINCSTATS. Fix this by adding a new error return path label after the use ...

SUSE CVE-2026-45997

In the Linux kernel, the following vulnerability has been resolved: scsi: sd: fix missing putdisk when deviceadd&diskdev fails If deviceadd&sdkp-diskdev fails, putdevice runs scsidiskrelease, which frees the scsidisk but leaves the gendisk referenced. The deviceadddisk error path in sdprobe calls...

CVE-2026-45872

A flaw was found in the Linux kernel's scsi: smartpqi driver. The pqireportphysluns function fails to properly release allocated memory buffers under certain error conditions, such as encountering an unsupported data format or failed memory allocation. This oversight leads to a memory leak, which...

CVE-2026-45997

A flaw was found in the Linux kernel's SCSI disk sd driver. When adding a new device, a failure in deviceadd can lead to a resource leak where a gendisk remains referenced but is not properly freed. This missing cleanup, specifically the putdisk call, can result in resource exhaustion. A local...
