Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: mctp i2c: Initializing the event handler for read bytes A value of 0xff was set for I2C reads of the mctp-i2c device. Otherwise, reads will return “val” from the I2C bus driver. For I2c-aspeed and i2c-npcm7xx, this represents an...

Linux Distros Unpatched Vulnerability : CVE-2026-45865

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - mctp i2c: initialise event handler read bytes Set a 0xff value for i2c reads of an mctp-i2c device. Otherwise reads will return val from the i2c bus driver. For...

SUSE CVE-2026-45865

In the Linux kernel, the following vulnerability has been resolved: mctp i2c: initialise event handler read bytes Set a 0xff value for i2c reads of an mctp-i2c device. Otherwise reads will return "val" from the i2c bus driver. For i2c-aspeed and i2c-npcm7xx that is a stack uninitialised u8. Teste...

CVE-2026-45865

The CVE-2026-45865 issue concerns the Linux kernel MCTP over I2C implementation. A read handling bug caused i2c reads from an mctp-i2c device to return 0xff instead of the data provided by the I2C bus driver, leaving the reads effectively biased to 0xff. The root cause is described as an uninitia...

CVE-2022-48806

The CVE-2022-48806 issue is confirmed in the Linux kernel under ee1004 EEPROM reads. The root cause was that ee1004_eeprom_read() could read more than the i2c block data limit because i2c_smbus_read_i2c_block_data_or_emulated() uses an unsigned 8-bit length; if the requested read spanned a 256-by...
