Astra Linux – vulnerability in linux-5.10, linux-6.1, linux-5.15

In the Linux kernel, the following vulnerability has been resolved: i2c: s3c24xx: check the size of the SMBUS message before using it The first byte of an i2c SMBUS message is the size; it should be verified to ensure that it is within the range of 0..I2CSMBUSBLOCKMAX prior to processing. This is...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: i2c: ismt: A buffer overflow bug has been fixed in ismtaccess. When the driver does not check the data from the user, the variable ‘data-block0’ may become very large, leading to a buffer overflow bug. The following log can revea...

kernel: i2c: stub: Reject I2C block transfers with invalid length

A flaw was found in the Linux kernel's i2c-stub driver. A local user with access to the /dev/i2c- device can exploit this vulnerability by issuing an I2C System Management Bus SMBus input/output control ioctl command with a specially crafted block transfer length. This invalid length can cause th...

CVE-2026-98204

A flaw was found in the Linux kernel's Synaptics RMI4 SMBus driver. When chunking write requests across the System Management Bus SMBus, the driver miscalculates the remaining data length for the final block. A local user can exploit this issue to trigger an out-of-bounds read past the input...
