Found In Version: 10.24.33.1
Severity: Standard
Applicable for: Wind River Linux LTS 24
Component/s: Kernel
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: reject mismatching sum of field_len with set key length
The field length description provides the length of each separated key
field in the concatenation, each field gets rounded up to 32-bits to
calculate the pipapo rule width from pipapo_init(). The set key length
provides the total size of the key aligned to 32-bits.
Register-based arithmetics still allows for combining mismatching set
key length and field length description, eg. set key length 10 and field
description 5, 4 ] leading to pipapo width of 12.
