To make things simpler, just call debugfs_lookup_and_remove() instead which handles all of the logic at once. The Linux kernel CVE team has assigned CVE-2023-53414 to this issue. Affected and fixed versions =========================== Fixed in 5.15.99 with commit 5a46d8bdaf03e8a4bb83f0c363326d9aa66cc122 Fixed in 6.1.16 with commit 3dec769caf337c55814fbf79ec8c91a3cce23bf3 Fixed in 6.2.3 with commit 995424f59ab52fb432b26ccb3abced63745ea041 Fixed in 6.3 with commit ad0e4e2fab928477f74d742e6e77d79245d3d3e7 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-2023-53414 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: drivers/scsi/snic/snic_debugfs.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/5a46d8bdaf03e8a4bb83f0c363326d9aa66cc122 https://git.kernel.org/stable/c/3dec769caf337c55814fbf79ec8c91a3cce23bf3 https://git.kernel.org/stable/c/995424f59ab52fb432b26ccb3abced63745ea041 https://git.kernel.org/stable/c/ad0e4e2fab928477f74d742e6e77d79245d3d3e7
