{"apiVersion":"1.0","identifier":"CVE-2026-72326","description":"In the Linux kernel, the following vulnerability has been resolved: net/sched: cake: reject overhead values that underflow length CAKE accepts signed overhead values and stores them in an s16, but the adjusted packet length calculation uses unsigned arithmetic. A negative effective length can therefore wrap to a large value. Such configurations make rate accounting depend on integer wraparound rather than on the packet size userspace intended to model. A static netlink lower bound is not enough because packets reaching CAKE can be smaller than any reasonable manual-overhead allowance. Fold the signed overhead adjustment into the existing datapath MPU clamp so negative adjusted lengths are clamped before link-layer framing adjustments.","publishedAt":"2026-08-15T06:22:05","lastModifiedAt":"2026-08-17T06:18:36","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72326","cvssScore":null,"cvssVector":"Pending","epssProbability":0.0022,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72326","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72326","en":"https://www.redsauce.net/en/cves/CVE-2026-72326","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72326","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72326","de":"https://www.redsauce.net/de/cves/CVE-2026-72326","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72326","el":"https://www.redsauce.net/el/cves/CVE-2026-72326"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72326"}}
