PatchTheCVECVE-2010-3904: Linux Kernel Improper Input Validation Vulnerability
CVE-2010-3904 is a high-severity flaw (CVSS 7.8) affecting linux kernel, opensuse, linux enterprise desktop, reported as exploited in the wild. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
Why this priority
- High severity
- EPSS top 3%: very likely to be exploited
- Exploited in the wild (CISA KEV)
- Public exploit reference
- On your watchlist
A fixed release or distro patch exists.
