{"apiVersion":"1.0","identifier":"CVE-2026-80691","description":"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.","publishedAt":"2026-08-28T08:16:54","lastModifiedAt":"2026-08-28T08:16:54","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-80691","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00168,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-80691","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-80691","en":"https://www.redsauce.net/en/cves/CVE-2026-80691","fr":"https://www.redsauce.net/fr/cves/CVE-2026-80691","pt":"https://www.redsauce.net/pt/cves/CVE-2026-80691","de":"https://www.redsauce.net/de/cves/CVE-2026-80691","sk":"https://www.redsauce.net/sk/cves/CVE-2026-80691","el":"https://www.redsauce.net/el/cves/CVE-2026-80691"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-80691"}}
