Linux Distros Unpatched Vulnerability : CVE-2022-48806

medium Nessus Plugin ID 225756

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- In the Linux kernel, the following vulnerability has been resolved: eeprom: ee1004: limit i2c reads to I2C_SMBUS_BLOCK_MAX Commit effa453168a7 (i2c: i801: Don't silently correct invalid transfer size) revealed that ee1004_eeprom_read() did not properly limit how many bytes to read at once. In particular, i2c_smbus_read_i2c_block_data_or_emulated() takes the length to read as an u8. If count == 256 after taking into account the offset and page boundary, the cast to u8 overflows. And this is common when user space tries to read the entire EEPROM at once. To fix it, limit each read to I2C_SMBUS_BLOCK_MAX (32) bytes, already the maximum length i2c_smbus_read_i2c_block_data_or_emulated() allows. (CVE-2022-48806)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
