| Subject: CVE-2024-43822: ASoc: PCM6240: Return directly after a failed devm_kzalloc() in pcmdevice_i2c_probe() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ASoc: PCM6240: Return directly after a failed devm_kzalloc() in pcmdevice_i2c_probe() |
| |
| The value “-ENOMEM” was assigned to the local variable “ret” |
| in one if branch after a devm_kzalloc() call failed at the beginning. |
| This error code will trigger then a pcmdevice_remove() call with a passed |
| null pointer so that an undesirable dereference will be performed. |
| Thus return the appropriate error code directly. |
| |
| The Linux kernel CVE team has assigned CVE-2024-43822 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/fa6f16eff7320c91e908309e31be34cbbe4b7e58 |
