| Subject: CVE-2024-58003: media: i2c: ds90ub9x3: Fix extra fwnode_handle_put() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| media: i2c: ds90ub9x3: Fix extra fwnode_handle_put() |
| |
| The ub913 and ub953 drivers call fwnode_handle_put(priv->sd.fwnode) as |
| part of their remove process, and if the driver is removed multiple |
| times, eventually leads to put "overflow", possibly causing memory |
| corruption or crash. |
| |
| The fwnode_handle_put() is a leftover from commit 905f88ccebb1 ("media: |
| i2c: ds90ub9x3: Fix sub-device matching"), which changed the code |
| related to the sd.fwnode, but missed removing these fwnode_handle_put() |
| calls. |
| |
| The Linux kernel CVE team has assigned CVE-2024-58003 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: |
