{"apiVersion":"1.0","identifier":"CVE-2026-74545","description":"In the Linux kernel, the following vulnerability has been resolved: rtase: fix double free of multi-frag skb on DMA map failure In rtase_start_xmit(), when the head buffer DMA mapping fails after rtase_xmit_frags() has mapped all fragments, the error path clears the fragment descriptors with rtase_tx_clear_range(), which frees the skb through the last-frag slot and accounts tx_dropped. Control then falls through to the common error label, which frees the same skb a second time and counts it again. Return right after clearing the fragments when the skb owns frags; the no-frag case still drops through and frees the head skb once.","publishedAt":"2026-08-15T13:17:59","lastModifiedAt":"2026-08-17T06:19:51","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74545","cvssScore":9.8,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00457,"riskScore":1.02,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74545","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74545","en":"https://www.redsauce.net/en/cves/CVE-2026-74545","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74545","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74545","de":"https://www.redsauce.net/de/cves/CVE-2026-74545","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74545","el":"https://www.redsauce.net/el/cves/CVE-2026-74545"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74545"}}
