Detailsinfo

A vulnerability, which was classified as problematic, was found in Linux Kernel up to 7.2-rc1. Affected is the function adm1275_probe of the file drivers/hwmon/adm1275.c of the component hwmon. The manipulation with an unknown input leads to a out-of-bounds vulnerability. CWE is classifying the issue as CWE-125. The product reads data past the end, or before the beginning, of the intended buffer. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: hwmon: adm1275: Prevent reading uninitialized stack While adding support for the ROHM BD127X0 hot-swap controllers, sashiko reported an error in device-name comparison, which can lead to reading uninitialized stack memory. Quoting Sashiko: This is a pre-existing issue, but I noticed that just before this block in adm1275_probe(), there might be an out-of-bounds stack read: ret = i2c_smbus_read_block_data(client, PMBUS_MFR_MODEL, block_buffer); if (ret < 0) { ... } for (mid = adm1275_id; mid->name[0]; mid++) { if (!strncasecmp(mid->name, block_buffer, strlen(mid->name))) break; } Since i2c_smbus_read_block_data() reads up to 32 bytes into the uninitialized stack array block_buffer without appending a null terminator, strncasecmp() could read past the valid bytes returned in ret. For example, if the device returns a shorter string like "adm12", checking it against "adm1275" up to the length of "adm1275" will continue reading into uninitialized stack bounds. Prevent reading uninitialized memory by zeroing the stack array.

The advisory is shared for download at git.kernel.org. This vulnerability is traded as CVE-2026-72396 since 08/09/2026. The exploitability is told to be easy. The attack needs to be approached locally. Additional levels of successful authentication are necessary for exploitation. There are known technical details, but no exploit is available.
