SUSE CVE-2026-46066

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

The CVE-2026-46068 entry documents a Linux kernel crypto issue in the nx subsystem (nx842_crypto_alloc_ctx/nx842_crypto_free_ctx). Root cause: bounce buffers allocated with __get_free_pages() using BOUNCE_BUFFER_ORDER (order 2, 4 pages) were freed with free_page() instead of matching free_pages()...

In the Linux kernel, the following vulnerability has been resolved: usb: chipidea: udc: fix DMA and SG cleanup in epnuke The ChipIdea UDC driver can encounter "not page aligned sg buffer" errors when a USB device is reconnected after being disconnected during an active transfer. This occurs becau...

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...
