The version of kernel installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-35997 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

"The version of kernel installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore,
affected by a vulnerability as referenced in the CVE-2024-35997 advisory.
- In the Linux kernel, the following vulnerability has been resolved: HID: i2c-hid: remove
I2C_HID_READ_PENDING flag to prevent lock-up The flag I2C_HID_READ_PENDING is used to serialize I2C
operations. However, this is not necessary, because I2C core already has its own locking for that. More
importantly, this flag can cause a lock-up: if the flag is set in i2c_hid_xfer() and an interrupt happens,
the interrupt handler (i2c_hid_irq) will check this flag and return immediately without doing anything,
then the interrupt handler will be invoked again in an infinite loop. Since interrupt handler is an RT
task, it takes over the CPU and the flag-clearing task never gets scheduled, thus we have a lock-up.
Delete this unnecessary flag. (CVE-2024-35997)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
