Threats Tagged 'cve-2025-71116'

Multiple security vulnerabilities have been identified in the Linux kernel packages used by Red Hat Enterprise Linux 8.4, including issues in libceph, netfilter, Bluetooth SCO, mptcp, tcp, ALSA, and RDMA components. These vulnerabilities include out-of-bounds reads, use-after-free, race conditions, double free, and improper checks that could lead to system instability or potential security breaches. Red Hat has issued an important security advisory with updates addressing these issues. The update requires a system reboot to take effect.

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * kernel: geneve: Fix use-after-free in geneve_find_dev().
