In the Linux kernel, the following vulnerability has been resolved: cpufreq: sun50i: prevent out-of-bounds access A KASAN enabled kernel reports an out-of-bounds access when handling the nvmem cell in the sun50i cpufreq driver: ================================================================== BUG: KASAN: slab-out-of-bounds in sun50i_cpufreq_nvmem_probe+0x180/0x3d4 Read of size 4 at addr ffff000006bf31e0 by task kworker/u16:1/38 This is because the DT specifies the nvmem cell as covering only two bytes, but we use a u32 pointer to read the value. DTs for other SoCs indeed specify 4 bytes, so we cannot just shorten the variable to a u16. Fortunately nvmem_cell_read() allows to return the length of the nvmem cell, in bytes, so we can use that information to only access the valid portion of the data. To cover multiple cell sizes, use memcpy() to copy the information into a zeroed u32 buffer, then also make sure we always read the data in little endian fashion, as this is how the da...
