CVE-2026-89458
CVE-2026-89458 affects the s390/dasd driver in the Linux kernel. The function dasd_int_handler() completes an NRF read of an unallocated ESE track by calling ese_read() and unconditionally marking the request as DASD_CQR_SUCCESS. However, dasd_eckd_ese_read() can return an error before zeroing th...

CVE-2026-89456
CVE-2026-89456 affects the Linux kernel 's s390/dasd (Direct Access Storage Device) driver. During error recovery path (ERP) processing, dasd_default_erp_postaction() fails to propagate the proc_bytes field from a finished ERP request back to the original request. When a disk read is partially co...
CVE-2026-89457
CVE-2026-89457 affects the s390/dasd subsystem in the Linux kernel. During dasd_generic_set_online(), a device's discipline is assigned before check_device() allocates device->private. Several sysfs show/store handlers dereference this pointer without a null check, so an unprivileged read of a...

CVE-2026-80679
A flaw was found in the Linux kernel. Specifically, within the s390/dasd component, the dasdreleasespace function incorrectly checks a function pointer by using a logical AND operator instead of a logical OR operator. This error can lead to a NULL pointer dereference, which may cause a system cra...
CVE-2026-80710
A flaw was found in the Linux kernel's s390/dasd component. An integer truncation vulnerability in the dasdeckdcheckdeviceformat function can lead to an undersized buffer allocation. This allows a local attacker to write past the end of the allocated buffer, potentially causing memory corruption...
