**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to the `load unaligned zeropad` function in the arm64 component of the Linux kernel. It involves the incorrect extraction of `data` and `addr` register indices from `ex->type` instead of `ex->data`. This can lead to the treatment of `X0` as the address register and `X4` as the data register, potentially causing the dereference of an arbitrary address and corruption of `X4`, resulting in arbitrary behavior within `load unaligned zeropad` and its caller. The problem is fixed by extracting both values from `ex->data` as originally intended. On an MTE-enabled QEMU image, this issue results in a crash due to a kernel NULL pointer dereference. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
