| Subject: CVE-2024-53083: usb: typec: qcom-pmic: init value of hdr_len/txbuf_len earlier |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| usb: typec: qcom-pmic: init value of hdr_len/txbuf_len earlier |
| |
| If the read of USB_PDPHY_RX_ACKNOWLEDGE_REG failed, then hdr_len and |
| txbuf_len are uninitialized. This commit stops to print uninitialized |
| value and misleading/false data. |
| |
| The Linux kernel CVE team has assigned CVE-2024-53083 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/35925e2b7b404cad3db857434d3312b892b55432 |
