Echo: linux: security update to 6.1.176-1

medium Tenable Self-Hosted Container Security Plugin ID 464750

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: i2c: dev: prevent integer overflow in
 I2C_TIMEOUT ioctl While fuzzing with Syzkaller, a persistent `schedule_timeout: wrong timeout value`
 warning was observed, accompanied by SMBus controller state machine corruption. The I2C_TIMEOUT ioctl
 accepts a user-provided timeout in multiples of 10 ms. The user argument is checked against INT_MAX, but
 it is subsequently multiplied by 10 before being passed to msecs_to_jiffies(). A malicious user can pass a
 large value (e.g., 429496729) that passes the `arg > INT_MAX` check but overflows when multiplied by 10.
 This results in a truncated 32-bit unsigned value that bypasses the internal `(int)m < 0` check in
 `msecs_to_jiffies()`. The truncated value is then assigned to `client->adapter->timeout` (a signed 32-bit
 int), which is reinterpreted as a negative number. When passed to wait_for_completion_timeout(), this
 negative value undergoes sign extension to a 64-bit unsigned long, triggering the `schedule_timeout`
 warning and causing premature returns. This leaves the SMBus state machine in an unrecoverable state,
 constituting a local Denial of Service (DoS). Fix this by bounding the user argument to `INT_MAX / 10`.
