In the Linux kernel, the following vulnerability has been resolved: iommufd: Use sizeof(hdr) instead of sizeof(hdr) in veventq read The bound-check… (CVE-2026-64293)CVE-2026-64293 0 A vulnerability in the Linux kernel's iommufd component involves an incorrect size check in the veventq read function. The code uses sizeof(hdr), which measures the pointer size, instead of sizeof(*hdr), the size of the actual structure, causing an undercount on 32-bit systems. This can lead to copying more data than the buffer can hold, potentially resulting in a buffer overflow. The issue is latent on 64-bit systems if the structure size grows beyond pointer size. The vulnerability has been resolved by correcting the size check to use sizeof(*hdr). Join the discussion | GCVE Database | 07/25/2026, 12:31:29 UTC Added: 07/25/2026, 23:09:02 UTC |
