Details: This update includes the following RPMs:
netavark:
* netavark-2.0.0-1.hum1 (aarch64, x86_64)

A flaw was found in HdrHistogram. A local attacker can exploit a vulnerability in the `decodeFromCompressedByteBuffer` function by manipulating the `lengthOfCompressedContents` argument. This manipulation leads to uncontrolled memory allocation, which can result in a Denial of Service (DoS) condition, making the affected system unavailable.
