CVE-2026-74423
The CVE-2026-74423 issue is in the Linux kernel, specifically accel/amdxdna: there is a leak when pin_user_pages_fast() pins fewer pages than requested. The pages that were successfully pinned are not released on failure. The documented fix unpins any partially pinned pages before returning failu...
CVE-2026-64280
In the Linux kernel, the following vulnerability has been resolved: fpga: dfl-afu: validate DMA mapping length in afudmamapregion afuioctldmamap accepts a 64-bit length from userspace via DFLFPGAPORTDMAMAP ioctl without an upper bound check. The value is passed to afudmapinpages where npages is...
CVE-2026-64280
The CVE concerns the Linux kernel’s FPGA driver for DFL FPGA management (fpga: dfl-afu). A 64-bit length passed via the DFL_FPGA_PORT_DMA_MAP ioctl to afu_ioctl_dma_map() can overflow when computing the number of pages (length >> PAGE_SHIFT) passed to pin_user_pages_fast(), since npages is ...
PT-2026-64501
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists where afu ioctl dma map accepts a 64-bit length from userspace via the DFL FPGA PORT DMA MAP ioctl without an upper bound check. This value is passed to afu dma pin pages...

Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerabilities have been resolved: xen/privcmd: fixed the error exit of privcmdioctldmop The error exit of privcmdioctldmop calls unlockpages, potentially with pages being NULL, leading to a NULL dereference. Additionally, lockpages does not check whether...
SUSE CVE-2023-54239
In the Linux kernel, the following vulnerability has been resolved: iommufd: Check for uptr overflow syzkaller found that setting up a map with a user VA that wraps past zero can trigger WARNONs, particularly from pinuserpages weirdly returning 0 due to invalid arguments. Prevent creating a pages...
SUSE CVE-2022-49989
In the Linux kernel, the following vulnerability has been resolved: xen/privcmd: fix error exit of privcmdioctldmop The error exit of privcmdioctldmop is calling unlockpages potentially with pages being NULL, leading to a NULL dereference. Additionally lockpages doesn't check for pinuserpagesfast...
CVE-2022-48700
In the Linux kernel, the following vulnerability has been resolved: vfio/type1: Unpin zero pages There's currently a reference count leak on the zero page. We increment the reference via pinuserpagesremote, but the page is later handled as an invalid/reserved page, therefore it's not accounted...
