What to do
AI-suggested
A fix has been implemented in the Linux kernel by modifying the error check to handle zero-length reads as errors, preventing out-of-bounds access. Users should apply the official Linux kernel update containing this fix once available. Patch status is not explicitly confirmed in the provided data; check the Linux kernel advisories for the fixed version.
Description
A vulnerability in the Linux kernel's hwmon subsystem (tps53679 driver) allows out-of-bounds stack read due to improper handling of zero-length block reads from i2c_smbus_read_block_data(). The issue is fixed by treating zero-length reads as errors, preventing access to memory before the buffer.
