CISA KEV Advisory
Linux Kernel Improper Input Validation Vulnerability
Linux Kernel contains an improper input validation vulnerability in the Reliable Datagram Sockets (RDS) protocol implementation that allows local users to gain privileges via crafted use of the sendmsg and recvmsg system calls.
The impacted product is end-of-life and should be disconnected if still in use.
Risk Analysis
This high-severity vulnerability in the Linux Kernel's Reliable Datagram Sockets (RDS) protocol allows local users to gain privileges through crafted use of system calls. Its inclusion in CISA's KEV catalog and active exploitation in the wild make it a critical concern, despite a low EPSS score of 0.01744.
This vulnerability is actively being exploited in the wild, as confirmed by its presence in CISA's KEV catalog. Attackers are leveraging crafted system calls to gain privileges.
Apply the latest security updates for the Linux Kernel to address the improper input validation in the RDS protocol. Restrict local user access and ensure systems are regularly patched.
Technical Analysis
CVE-2010-3904 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2010-3904 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
