AI-suggested
A patch is available and should be applied promptly to all affected Linux kernel versions. The vendor advisory confirms that this vulnerability has been resolved. Users should update their Linux kernel to the fixed versions as provided by their distribution.
Description
A heap buffer overflow vulnerability in the Linux kernel's airoha network driver was fixed. The flaw involved incorrect allocation size for a u16 pointer, leading to out-of-bounds writes when certain conditions were met. This could cause a kernel crash and potentially allow an attacker to compromise system integrity. The vulnerability affects specific Linux kernel versions and has a high CVSS score of 9.8. A patch is available to address this issue.
