{"apiVersion":"1.0","identifier":"CVE-2026-80522","description":"In the Linux kernel, the following vulnerability has been resolved: crypto: tegra - fix rctx->cryptlen calculation in tegra_gcm_do_one_req() Perform rctx->cryptlen calculation in tegra_gcm_do_one_req() the same way it is done in tegra_ccm_crypt_init(). The current formulae may lead to a crash if a caller does not call tegra_gcm_setauthsize() and so ctx->authsize remains zero. Then a decrypt operation with incorrect rctx->cryptlen will lead to a write beyound rctx->dst_sg buffer. As a follow-up cleanup delete struct tegra_aead_ctx->authsize field since it appears to be completely unused. Also simplify tegra_ccm_setauthsize() and tegra_gcm_setauthsize() functions respectively.","publishedAt":"2026-08-26T15:17:05","lastModifiedAt":"2026-08-27T06:17:31","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-80522","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00128,"riskScore":0.79,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-80522","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-80522","en":"https://www.redsauce.net/en/cves/CVE-2026-80522","fr":"https://www.redsauce.net/fr/cves/CVE-2026-80522","pt":"https://www.redsauce.net/pt/cves/CVE-2026-80522","de":"https://www.redsauce.net/de/cves/CVE-2026-80522","sk":"https://www.redsauce.net/sk/cves/CVE-2026-80522","el":"https://www.redsauce.net/el/cves/CVE-2026-80522"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-80522"}}
