CVE-2010-3904

CVE-2010-3904 is a high-severity (CVSS 7.8) vulnerability in Linux Kernel. CISA added it to the Known Exploited Vulnerabilities catalog on May 12, 2023, which means exploitation in the wild has been confirmed; US federal agencies had to remediate it by June 2, 2023. CISA does not currently list it as used in ransomware campaigns. Linux has 32 vulnerabilities in the KEV catalog, 2 of them linked to ransomware.

The rds_page_copy_user function in net/rds/page.c in the Reliable Datagram Sockets (RDS) protocol implementation in the Linux kernel before 2.6.36 does not properly validate addresses obtained from user space, which allows local users to gain privileges via crafted use of the sendmsg and recvmsg system calls.
