In the Linux kernel, the following vulnerability has been resolved: iouring/net: inherit IORINGCQEFBUFMORE across bundle recv retries When a bundle recv retries inside iorecvfinish, the merge logic OR the saved cflags from the previous iteration with the cflags returned by the new iteration: cfla...

CVE-2026-53191

CVE-2026-53191 affects the Linux kernel io_uring/net path. In bundle recv retries (with incremental mode and provided buffer rings IOU_PBUF_RING_INC), a memory handling bug caused IORING_CQE_F_BUF_MORE to be dropped during flag merge, allowing the kernel to leave a stale BUF_MORE in carried flags...

In the Linux kernel, the following vulnerability has been resolved: drm/virtio: fix dmafence refcount leak on error in virtiogpudmafencewait dmafenceunwrapforeach internally calls dmafenceunwrapfirst which does cursor-chain = dmafencegethead, taking an extra reference. On normal loop completion,...

CVE-2026-53185

CVE-2026-53185 concerns the Linux kernel zram subsystem. The issue is a use-after-free in zram_bvec_write_partial(), where zram_read_page() can dispatch reads asynchronously for ZRAM_WB slots and return before the backing read completes. The caller may then operate on a buffer that is freed, risk...

CVE-2026-53181

CVE-2026-53181 affects the Linux kernel vsock/vmci stack. On failing handshake, vmci_transport_recv_listen() could leave sk_ack_backlog incremented (due to missing sk_acceptq_removed() call), allowing backlog growth toward sk_max_ack_backlog and a possible listener denial of new connections (-ECO...

CVE-2026-53172

The CVE-2026-53172 issue in the Linux kernel’s accel/ethosu component is a local-privilege/heap corruption flaw caused by an incorrect mask (0x7f) when processing NPU_SET_IFM_REGION. This allows a userspace caller to supply a region index > 7, writing up to 1016 bytes past the start of region_...

CVE-2026-53172 accel/ethosu: fix IFM region index out-of-bounds in command stream parser

In the Linux kernel, the following vulnerability has been resolved: accel/ethosu: fix IFM region index out-of-bounds in command stream parser NPUSETIFMREGION extracts the region index with param & 0x7f, giving a maximum value of 127. However regionsize and outputregion in struct...

CVE-2026-53155

In Linux kernels, CVE-2026-53155 relates to mm/huge_memory and device-private PMD entries. A commit (65edfda6f3f2) updated set_pmd_migration_entry() to use pmdp_huge_get_and_clear() in the softleaf case but did not adjust the function fully, causing incorrect use of pmd_write(), pmd_soft_dirty(),...
