CVE-2026-89586

A flaw was found in the Linux kernel's libata-scsi component. This vulnerability occurs when the system attempts to perform Data Set Management DSM TRIM operations on storage devices with logical sector sizes exceeding 2048 bytes. Due to an incorrect handling of the TRIM descriptor generation,...

CVE-2026-89515

A flaw was found in the Linux kernel's SCSI core component. When processing data transfers using scatter-gather lists, the system does not properly initialize padding bytes for unaligned data elements. This can result in the exposure of uninitialized memory, potentially allowing a local attacker ...

CVE-2026-89586

CVE-2026-89586 affects the Linux kernel libata-scsi component. The root cause is that ata_format_dsm_trim_descr() clamps the TRIM descriptor copy length to 2048 bytes (ATA_SCSI_RBUF_SIZE), while the caller compares the result against the device's logical sector size . On devices with sector sizes...
