CVE-2024-38580

16
FAUCET Score

CVE-2024-38580 is a medium-severity vulnerability in the Linux kernel's epoll mechanism, affecting the handling of file lifetimes. Specifically, it involves a race condition where epoll's call to vfs_poll() might use a file pointer that has already had its reference count drop to zero, potentially leading to a use-after-free scenario. This local vulnerability has high attack complexity and requires low privileges, with a potential impact of high availability loss. There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
