The Linux kernel CVE team has assigned CVE-2026-90062 to this issue.

Affected files ============== The file(s) affected by this issue are: net/netfilter/nf_tables_api.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/923f824f30faebc5560c3061a595063cecdbdbb8 https://git.kernel.org/stable/c/6e7ad6e69be4751ab2476042c70c600bdaa8d4f2 https://git.kernel.org/stable/c/309acbab74e46114246bf4346c9b60b3d8cb4fcd https://git.kernel.org/stable/c/79eafe22ab0a650996da2b3e5d94a12c3e16f3aa https://git.kernel.org/stable/c/52febaf1d311d6ede312b2ec7692a309714f9554 https://git.kernel.org/stable/c/d5497644329d3a01e951aba76561bbd883ff6b0c https://git.kernel.org/stable/c/6a7d3b074cfbb64513f5f92d60ab1b216ae98076 https://git.kernel.org/stable/c/b1881d362e1924b66f6016c3efd28807032b41bf
