Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to a potential use-after-free in the Linux kernel's hsr module. This occurs when the skb is delivered to netif rx(), which may free it, and subsequent dereferencing of skb can trigger a use-after-free. This could allow an attacker to cause a denial of service or potentially elevate their privileges, impacting the confidentiality, integrity, and availability of protected information.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
