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. Affected and fixed versions =========================== Issue introduced in 5.13 with commit dfc1193d4dbd and fixed in 5.15.161 with commit 27600e0c5272 Issue introduced in 5.13 with commit dfc1193d4dbd and fixed in 6.1.93 with commit 11c731386ed8 Issue introduced in 5.13 with commit dfc1193d4dbd and fixed in 6.6.33 with commit 2d5ca6e4a287 Issue introduced in 5.13 with commit dfc1193d4dbd and fixed in 6.8.12 with commit 06d17744b77b Issue introduced in 5.13 with commit dfc1193d4dbd and fixed in 6.9.3 with commit fcf5f1b5f308 Issue introduced in 5.13 with commit dfc1193d4dbd and fixed in 6.10-rc1 with commit d998ddc86a27 Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community.

Affected files ============== The file(s) affected by this issue are: drivers/thermal/qcom/tsens.c 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/27600e0c5272a262b0903e35ae1df37d33c5c1ad https://git.kernel.org/stable/c/11c731386ed82053c2759b6fea1a82ae946e5e0f https://git.kernel.org/stable/c/2d5ca6e4a2872e92a32fdfd87e04dd7d3ced7278 https://git.kernel.org/stable/c/06d17744b77bc6cb29a6c785f4fad8c4163ee653 https://git.kernel.org/stable/c/fcf5f1b5f308f2eb422f6aca55d295b25890906b https://git.kernel.org/stable/c/d998ddc86a27c92140b9f7984ff41e3d1d07a48f
