CVE-2025-71311

A flaw was found in the Linux kernel's fs/ntfs3 component. When new memory pages folios are allocated for the NTFS3 file system without being properly initialized, and a read operation is skipped, parts of these folios may contain uninitialized memory. This can lead to a memory corruption...

CVE-2026-46123

A flaw was found in the Linux kernel's virtio Bluetooth virtiobt driver. A malicious or faulty virtualized Bluetooth device could send a specially crafted message with an incorrect length. This could lead to the kernel reading uninitialized memory, potentially exposing sensitive information from...

CVE-2026-46151

A flaw was found in the Linux kernel's USB printer usblp driver. A malicious USB printer can exploit a heap leak vulnerability by sending a truncated device ID response. This can lead to the disclosure of up to 1021 bytes of uninitialized kernel memory, potentially exposing sensitive information ...

CVE-2026-46186

A flaw was found in the Linux kernel's virtiobt Bluetooth virtual device driver. An untrusted backend can exploit this vulnerability by sending malformed Bluetooth packets with an insufficient header length. This can cause the system to read uninitialized kernel memory, potentially leading to...

CVE-2026-46123

Summary: CVE-2026-46123 affects the Linux kernel Bluetooth virtio_bt driver. The issue arises when virtbt_rx_work() skb_put(skb, len) uses an unvalidated len sourced from virtqueue_get_buf(), with the device exposing a 1000-byte RX buffer. Since alloc_skb() tailroom can exceed 1000, a malicious/b...
