Vulnerabilities description
- CVE-2025-38351
In the Linux kernel, the following vulnerability has been resolved: KVM: x86/hyper-v: Skip non-canonical addresses during PV TLB flush.
- CVE-2025-38614
A local unprivileged user can trigger this issue by creating deeply nested chains of epoll file descriptors using the standard epoll_create and epoll_ctl syscalls. No special capabilities or elevated rights are required — any user with the ability to open file descriptors can exploit it. This can lead to excessive kernel stack usage and ultimately a denial of service (system crash).
