# CVE-2026-80691

> 3.1 LOW

## Beschreibung

In the Linux kernel, the following vulnerability has been resolved:

scsi: target: iblock: Fix wrong PR ops NULL check for PREEMPT/RELEASE

In the iblock_execute_pr_out() function, PRO_PREEMPT,
PRO_PREEMPT_AND_ABORT, and PRO_RELEASE all perform callback capability
checks through ops->pr_clear. The error check allows unimplemented hooks
to pass through the gate, resulting dereferencing a NULL function
pointer.

Check whether the hooks that need to be called are supported.

## Patch verfügbar (OSV)

- Kernel ≥ 6.6.151
- Kernel ≥ 6.12.103
- Kernel ≥ 6.18.44
- Kernel ≥ 7.1.8
