{"apiVersion":"1.0","identifier":"CVE-2026-80645","description":"In the Linux kernel, the following vulnerability has been resolved: rapidio/tsi721: prevent a bad dereference in tsi721_db_dpc() With a list_for_each() loop, if we don-t find the item we are looking for in the list, then the loop exits with the iterator, which is -dbell- in this loop, pointing to invalid memory. This code uses the -found- variable to determine if we have found the doorbell we are looking for or not. However, the problem that the -found- variable needs to be set to false at the start of each iteration, otherwise after the first correct doorbell, then everything is marked as found. Reset the -found- to false at the start of the iteration and move the variable inside the loop.","publishedAt":"2026-08-28T08:16:49","lastModifiedAt":"2026-08-28T08:16:49","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-80645","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00176,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-80645","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-80645","en":"https://www.redsauce.net/en/cves/CVE-2026-80645","fr":"https://www.redsauce.net/fr/cves/CVE-2026-80645","pt":"https://www.redsauce.net/pt/cves/CVE-2026-80645","de":"https://www.redsauce.net/de/cves/CVE-2026-80645","sk":"https://www.redsauce.net/sk/cves/CVE-2026-80645","el":"https://www.redsauce.net/el/cves/CVE-2026-80645"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-80645"}}
