The current formulae may lead to a\ncrash if a caller does not call tegra_gcm_setauthsize() and so ctx->authsize\nremains zero. Then a decrypt operation with incorrect rctx->cryptlen will\nlead to a write beyound rctx->dst_sg buffer.\n\nAs a follow-up cleanup delete struct tegra_aead_ctx->authsize field since\nit appears to be completely unused. Also simplify tegra_ccm_setauthsize()\nand tegra_gcm_setauthsize() functions respectively.","published":"2026-08-26T14:37:03.180Z","modified":"2026-08-28T03:47:28.898291366Z","cvss":{"score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"6.12.105"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/360f2974fcea49c61f6d6f81554741a9eeee7168"},{"type":"WEB","url":"https://git.kernel.org/stable/c/99a18e1d979e0fad3aaf9c65ae6696897c1d9869"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c6237834d9994de209cb90c7a2c461247bce8e90"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cd6991001bf0681ed0bcf21f9cc3d261d749b2bb"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80522.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80522"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-28T03:47:28.898291366Z"}}
