| Subject: CVE-2024-41029: nvmem: core: limit cell sysfs permissions to main attribute ones |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| nvmem: core: limit cell sysfs permissions to main attribute ones |
| |
| The cell sysfs attribute should not provide more access to the nvmem |
| data than the main attribute itself. |
| For example if nvme_config::root_only was set, the cell attribute |
| would still provide read access to everybody. |
| |
| Mask out permissions not available on the main attribute. |
| |
| The Linux kernel CVE team has assigned CVE-2024-41029 to this issue. |

| 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/aa066afaaac32caf2160d58d4e3010ee04421c62 |
