{"apiVersion":"1.0","identifier":"CVE-2026-80713","description":"In the Linux kernel, the following vulnerability has been resolved: io_uring: preserve task restrictions across exec Per-task restrictions apply to all rings created by a task. Once installed, they should not be dropped across exec. For a task that has used io_uring, the exec cancellation path calls __io_uring_free(). This frees both the task context and the per-task restriction, so a ring created after exec is unrestricted. Split task context cleanup into io_uring_free_tctx(), and use it from the exec cancellation path. Keep __io_uring_free() for final task cleanup, where both the context and restriction are released.","publishedAt":"2026-08-28T08:16:56","lastModifiedAt":"2026-08-28T08:16:56","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-80713","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00145,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-80713","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-80713","en":"https://www.redsauce.net/en/cves/CVE-2026-80713","fr":"https://www.redsauce.net/fr/cves/CVE-2026-80713","pt":"https://www.redsauce.net/pt/cves/CVE-2026-80713","de":"https://www.redsauce.net/de/cves/CVE-2026-80713","sk":"https://www.redsauce.net/sk/cves/CVE-2026-80713","el":"https://www.redsauce.net/el/cves/CVE-2026-80713"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-80713"}}
