CVE-2026-53164

A flaw was found in the Linux kernel's input/output memory management unit IOMMU Direct Memory Access DMA subsystem, specifically within the software IOMMU bounce buffer SWIOTLB mechanism. This vulnerability occurs when the system attempts to map a zero-length memory region, which can be triggere...

In the Linux kernel, the following vulnerability has been resolved: ceph: fix numops off-by-one when crypto allocation fails movedirtyfolioinpagearray may fail if the file is encrypted, the dirty folio is not the first in the batch, and it fails to allocate a bounce buffer to hold the ciphertext...

SUSE CVE-2026-46068

In the Linux kernel, the following vulnerability has been resolved: crypto: nx - fix bounce buffer leaks in nx842cryptoalloc,freectx The bounce buffers are allocated with getfreepages using BOUNCEBUFFERORDER order 2 = 4 pages, but both the allocation error path and nx842cryptofreectx release the...

CVE-2026-46066

A flaw was found in the Linux kernel's Ceph filesystem. When writing to encrypted CephFS files, a failure to allocate a bounce buffer for a dirty folio can lead to an off-by-one error in the numops counter. This inconsistency can cause a kernel panic, resulting in a Denial of Service DoS for the...

CVE-2026-46068

CVE-2026-46068 affects the Linux kernel's crypto nx path: bounce buffers allocated with _get_free_pages() (BOUNCE_BUFFER_ORDER) are freed with free_page() instead of free_pages(), causing memory leaks. The fix uses free_pages() with the matching order in nx842_crypto {alloc,free}_ctx. Affected: L...

CVE-2026-43250

CVE-2026-43250 affects the Linux kernel ChipIdea USB Device Controller (UDC) driver. The vulnerability arises when a USB device is reconnected during an active transfer, because _ep_nuke() returns requests without unmapping DMA buffers or cleaning bounce buffers, leaving stale DMA state (num_mapp...
