kernel: smb/client: fix out-of-bounds read in smb2_compound_op()

A flaw was found in the Linux kernel's Server Message Block SMB client. A remote attacker, acting as a malicious SMB server, could send a specially crafted, truncated response with an oversized buffer length. This could lead to an out-of-bounds read in the smb2compoundop function, allowing the...

CVE-2026-10643

Zephyr CVE-2026-10643 affects the IP socket recvmsg() ancillary-data path (insert_pktinfo in subsys/net/lib/sockets/sockets_inet.c). A check only compared msg_controllen to pktinfo_len, omitting the cmsg header size, allowing an under-checked window (e.g., 16–27 bytes for IPv4 IP_PKTINFO on a 64‑...

CVE-2026-49416 Integer overflow in vt(4) CONS_HISTORY ioctl

The CONSHISTORY ioctl handler did not adequately validate the requested history size. A large value caused an integer overflow in the buffer size calculation, resulting in a heap allocation smaller than expected. Subsequent initialization of the buffer wrote beyond the end of the allocation. An...

Name of the Vulnerable Software and Affected Versions Zephyr versions 3.6.0 through 4.4.0 Description An out-of-bounds write exists in the IP socket recvmsg implementation within the insert pktinfo function located in subsys/net/lib/sockets/sockets inet.c. The issue occurs because the validation ...

CVE-2026-53172

A flaw was found in the Linux kernel's accel/ethosu component. An incorrect mask used when processing the NPUSETIFMREGION command allows a local userspace caller to provide an out-of-bounds region index. This can lead to an out-of-bounds write, corrupting adjacent kernel heap data...

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-2026-46655

A flaw was found in virtio-win. A low-integrity process can issue an IOCTL request to viosock.sys!VIOSockSelect with a maliciously crafted request that causes an integer overflow. This allows the process to circumvent bounds checking, resulting in a heap overflow in the NonPagedPool kernel heap...
