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...

CVE-2026-80710

CVE-2026-80710 affects the s390/dasd subsystem of the Linux kernel. In dasd_eckd_check_device_format(), the variable fmt_buffer_size is declared as a 32-bit int, but the expression trkcount * rpt_max * sizeof(struct eckd_count) is evaluated at 64-bit width. When the track range (controlled by cal...
