Affected: Linux

In the Linux kernel, the following vulnerability has been resolved:

vsock/virtio: Coalesce only linear skb

vsock/virtio common tries to coalesce buffers in rx queue: if a linear skb (with a spare tail room) is followed by a small skb (length limited by GOOD_COPY_LEN = 128), an attempt is made to join them.

Since the introduction of MSG_ZEROCOPY support, assumption that a small skb will always be linear is incorrect. In the zerocopy case, data is lost and the linear skb is appended with uninitialized kernel memory.

Of all 3 supported virtio-based transports, only loopback-transport is affected. G2H virtio-transport rx queue operates on explicitly linear skbs; see virtio_vsock_alloc_linear_skb() in virtio_vsock_rx_fill(). H2G vhost-transport may allocate non-linear skbs, but only for sizes that are not considered for coalescence; see PAGE_ALLOC_COSTLY_ORDER in virtio_vsock_alloc_skb().

Ensure only linear skbs are coalesced. Note that skb_tailroom(last_skb) > 0 guarantees last_skb is linear.

It was discovered that the Linux kernel algif_aead module did not properly handle in-place cryptographic operations. This flaw is known as Copy Fail. A local attacker could use this to escalate privileges, or possibly escape a container. (CVE-2026-31431)

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - ARM64 architecture; - x86 architecture; - Cryptographic API; - Compute Acceleration Framework; - Drivers core; - Null block device driver; - Ublk userspace block driver; - Bluetooth drivers; - Counter interface drivers; - DMA engine subsystem; - DPLL subsystem; - GPU drivers; - HID subsystem; - Intel Trace Hub HW tracing drivers; - IIO ADC drivers; - IIO subsystem; - On-Chip Interconnect management framework; - IRQ chip drivers; - Modular ISDN driver; - LED subsystem; - Multiple devices driver; - UACCE accelerator framework; - MMC subsystem; - Ethernet bonding driver; - Network drivers; - Mellanox network drivers; - NVME drivers; - PHY drivers; - x86 platform drivers; - i.MX PM domains; - SCSI subsystem; - SLIMbus drivers; - SPI subsystem; - TCM subsystem; - W1 Dallas's 1-wire bus driver; - Xen hypervisor drivers; - BTRFS file system; - EFI Variable file system; - exFAT file system; - Ext4 file system; - HFS+ file system; - Network file system (NFS) client; - N…
