CVE-2026-68449 ata: sata_dwc_460ex: fix infinite loop in NCQ tag completion bit-scanning

In the Linux kernel, the following vulnerability has been resolved: ata: satadwc460ex: fix infinite loop in NCQ tag completion bit-scanning The hand-rolled bit-scanning loop in the NCQ completion path has an infinite loop bug. When tagmask has only high bits set e.g. 0x80000000, the inner while...

CVE-2026-68449

The CVE-2026-68449 issue affects the Linux kernel in the sata_dwc_460ex NCQ tag completion path. A hand-rolled bit-scanning loop could loop infinitely when tag_mask contains only high bits (e.g., 0x80000000); the inner loop shifts until overflow to 0, causing an infinite loop in hardirq context w...

CVE-2026-68448

The CVE-2026-68448 entry concerns the Linux kernel overlayfs copy_file_range path. Previously, cross-filesystem copy could proceed using the destination overlayfs’s mounter credentials, with the source file’s read path checked using the destination’s credentials. This could deny a permitted copy ...
