Add boundary check to prevent out of bound access. The Linux kernel CVE team has assigned CVE-2024-26702 to this issue. Affected and fixed versions =========================== Issue introduced in 5.0 with commit 121354b2eceb and fixed in 5.4.269 with commit 7200170e88e3 Issue introduced in 5.0 with commit 121354b2eceb and fixed in 5.10.210 with commit 36a49290d7e6 Issue introduced in 5.0 with commit 121354b2eceb and fixed in 5.15.149 with commit 8d5838a473e8 Issue introduced in 5.0 with commit 121354b2eceb and fixed in 6.1.79 with commit 176256ff8abf Issue introduced in 5.0 with commit 121354b2eceb and fixed in 6.6.18 with commit 1d8c67e94e9e Issue introduced in 5.0 with commit 121354b2eceb and fixed in 6.7.6 with commit 57d05dbbcd0b Issue introduced in 5.0 with commit 121354b2eceb and fixed in 6.8 with commit 792595bab492 Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community. Unaffected versions might change over time as fixes are backported to older supported kernel versions.

Affected files ============== The file(s) affected by this issue are: drivers/iio/magnetometer/rm3100-core.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/7200170e88e3ec54d9e9c63f07514c3cead11481 https://git.kernel.org/stable/c/36a49290d7e6d554020057a409747a092b1d3b56 https://git.kernel.org/stable/c/8d5838a473e8e6d812257c69745f5920e4924a60 https://git.kernel.org/stable/c/176256ff8abff29335ecff905a09fb49e8dcf513 https://git.kernel.org/stable/c/1d8c67e94e9e977603473a543d4f322cf2c4aa01 https://git.kernel.org/stable/c/57d05dbbcd0b3dc0c252103b43012eef5d6430d1 https://git.kernel.org/stable/c/792595bab4925aa06532a14dd256db523eb4fa5e
