In the Linux kernel, the following vulnerability has been resolved: iommufd: Set upper bounds on cache invalidation entry_num and entry_len… (CVE-2026-64289)CVE-2026-64289 0 A vulnerability in the Linux kernel's iommufd component involved unbounded user-controlled parameters entry_num and entry_len in the cache invalidation ioctl. Excessively large values could cause the kernel to perform long, uninterruptible operations, potentially triggering a soft-lockup watchdog or CPU pinning due to non-preemptible loops.
