The Linux kernel CVE team has assigned CVE-2026-74592 to this issue. Affected and fixed versions =========================== Fixed in 6.12.104 with commit 5f46705d96eb60587aa7035acfcbec977e08d620 Fixed in 6.18.45 with commit dd21c96a71e876c8df9ec546b885a2c5f47bbb05 Fixed in 7.1.9 with commit 0baed1fa2184c81e4baf76f445d3faa4b738c8f7 Fixed in 7.2 with commit b80bed5c871a80151351342c065579405ce77145 Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community. Unaffected versions might change over time as fixes are backported to older supported kernel versions. The official CVE entry at https://cve.org/CVERecord/?id=CVE-2026-74592 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: security/integrity/ima/ima_main.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/5f46705d96eb60587aa7035acfcbec977e08d620 https://git.kernel.org/stable/c/dd21c96a71e876c8df9ec546b885a2c5f47bbb05 https://git.kernel.org/stable/c/0baed1fa2184c81e4baf76f445d3faa4b738c8f7 https://git.kernel.org/stable/c/b80bed5c871a80151351342c065579405ce77145
