  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nhwmon: adm1275: Prevent reading uninitialized stack\n\nWhile adding support for the ROHM BD127X0 hot-swap controllers, sashiko\nreported an error in device-name comparison, which can lead to reading\nuninitialized stack memory.\n\nQuoting Sashiko:\n\nThis is a pre-existing issue, but I noticed that just before this block in\nadm1275_probe(), there might be an out-of-bounds stack read:\n\n    ret = i2c_smbus_read_block_data(client, PMBUS_MFR_MODEL, block_buffer);\n    if (ret \u003c 0) { ... }\n    for (mid = adm1275_id; mid-\u003ename[0]; mid++) {\n            if (!strncasecmp(mid-\u003ename, block_buffer, strlen(mid-\u003ename)))\n                    break;\n    }\n\nSince i2c_smbus_read_block_data() reads up to 32 bytes into the\nuninitialized stack array block_buffer without appending a null\nterminator, strncasecmp() could read past the valid bytes returned in ret.\n\nFor example, if the device returns a shorter string like \"adm12\", checking\nit against \"adm1275\" up to the length of \"adm1275\" will continue reading\ninto uninitialized stack bounds.\n\nPrevent reading uninitialized memory by zeroing the stack array.",
