| Subject: CVE-2024-38571: thermal/drivers/tsens: Fix null pointer dereference |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| thermal/drivers/tsens: Fix null pointer dereference |
| |
| compute_intercept_slope() is called from calibrate_8960() (in tsens-8960.c) |
| as compute_intercept_slope(priv, p1, NULL, ONE_PT_CALIB) which lead to null |
| pointer dereference (if DEBUG or DYNAMIC_DEBUG set). |
| Fix this bug by adding null pointer check. |
| |
| Found by Linux Verification Center (linuxtesting.org) with SVACE. |
| |
| The Linux kernel CVE team has assigned CVE-2024-38571 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: |
