CVE-2026-80931

A flaw was found in the Linux kernel's w1: ds28e17 1-Wire to I2C bridge driver. A malicious I2C slave device can provide an oversized length during an I2C block read operation. This causes the driver to read beyond the allocated buffer, leading to an out-of-bounds read of up to 222 bytes. This...

In the Linux kernel, the following vulnerability has been resolved: w1: ds28e17: reject an oversize length on an I2C block read w1f19i2cmastertransfer is the masterxfer for the DS28E17 1-Wire to I2C bridge. On an I2CMRECVLEN read, it takes the length from the device. The downstream slave puts a...

CVE-2026-80931

In the Linux kernel , the DS28E17 1-Wire to I2C bridge driver (w1 subsystem) contains an out-of-bounds read in w1_f19_i2c_master_transfer(). During an I2C_M_RECV_LEN read, the device-controlled length byte (0–255) is used to determine how many bytes to read into a 34-byte buffer (I2C_SMBUS_BLOCK_...

In the Linux kernel, the following vulnerability has been resolved: iio: magnetometer: ak8975: fix potential kernel stack memory leak Currently in the AK8975 driver there are four instances where potential uninitialized kernel stack memory leaks can occur. If i2c smbus read i2c block data or...

CVE-2026-43005 hwmon: (tps53679) Fix array access with zero-length block read

In the Linux kernel, the following vulnerability has been resolved: hwmon: tps53679 Fix array access with zero-length block read i2csmbusreadblockdata can return 0, indicating a zero-length read. When this happens, tps53679identifychip accesses bufret - 1 which is buf-1, reading one byte before t...
