CVE-2026-74466

In the Linux kernel, the following vulnerability has been resolved: s390/zcrypt: Close speculative mem read possibility The domain value is extracted from a given CCA or EP11 ioctl struct when a CPRB is about to be sent. Thus this is a user controlled value. Under some special conditions custom...

CVE-2026-74466

The CVE-2026-74466 vulnerability concerns the Linux kernel’s s390/zcrypt path. A domain value is extracted from a CCA or EP11 ioctl struct and, under certain conditions (custom device node, administrative load), is used as an array index after bounds checking without a speculation barrier. This c...

CVE-2026-74457 can: peak_usb: add bounds check for USB channel index

In the Linux kernel, the following vulnerability has been resolved: can: peakusb: add bounds check for USB channel index The channel control index ctrlidx is derived from rx-len which comes directly from a device USB payload. The mask 0x0f allows values 0-15, but the array size of usbif-dev is on...

CVE-2026-74457

The CVE-2026-74457 entry describes a Linux kernel issue in the can: peak_usb driver where ctrl_idx is derived from rx->len (USB payload). The mask 0x0f allows 0–15, but usb_if->dev[] is only size 2, causing heap out-of-bounds read and kernel panic in IRQ context. The fix adds bounds checks ...
