Threats Tagged 'cve-2026-23193'

Multiple security vulnerabilities have been identified in the Linux kernel packages used by Red Hat Enterprise Linux versions 8.8 and 10.0. These include denial of service due to deadlocks, use-after-free, heap overflow, memory corruption, and privilege escalation issues affecting various kernel subsystems such as hugetlb folio migration, netfilter, RDMA umad, KVM, NFSv4.0, and CAN raw sockets. Red Hat has released security updates addressing these issues, and applying these updates requires a system reboot.
