kernel: net: mana: validate rx_req_idx to prevent out-of-bounds array access

A flaw was found in the Linux kernel's mana network driver. In Confidential Virtual Machines VMs, a missing bounds check when processing network events can allow a malicious hardware component or a compromised VM to write data outside of an intended memory region. This out-of-bounds access could...

kernel: smb: client: fix change notify replay double-free

A flaw was found in the Linux kernel's Server Message Block SMB client. This vulnerability occurs due to a double-free error when handling change notify replies. If a response attempt returns a replayable error and frees its buffer, and then SMB2notifyinit fails, the same buffer can be freed agai...

kernel: ALSA: virtio: Validate control metadata from the device

A flaw was found in the Linux kernel's ALSA virtio sound driver. A malicious or buggy virtio device can provide invalid control metadata, such as an unknown control type or an oversized value count. The driver's control handling trusts this unvalidated metadata, leading to out-of-bounds access wh...

kernel: nvmet-auth: reject short AUTH_RECEIVE buffers

A flaw was found in the nvmet-auth component of the Linux kernel. A remote attacker, by sending a specially crafted AUTHRECEIVE buffer to an NVMe-oF NVM Express over Fabrics target with in-band authentication enabled, can trigger a heap out-of-bounds write. This vulnerability arises because the...

kernel: netfilter: nfnetlink_cthelper: fix OOB read in nfnl_cthelper_dump_table()

A flaw was found in the Linux kernel's nfnetlinkcthelper component. This vulnerability, an out-of-bounds read, occurs in the nfnlcthelperdumptable function when a network connection tracking helper is removed during a dump operation, leading to a bypassed bounds check. A local attacker could...

kernel: NFSv4/pNFS: reject zero-length r_addr in nfs4_decode_mp_ds_addr

A flaw was found in the Linux kernel's NFSv4/pNFS implementation. The nfs4decodempdsaddr function, responsible for decoding network address information, does not properly handle zero-length raddr opaque data. A malicious or compromised metadata server can exploit this by providing a zero-length...

CVE-2026-40019

A flaw was found in Dovecot's ManageSieve login process. An unauthenticated attacker can exploit this vulnerability by sending a specially crafted, truncated quoted argument. This action causes the process to enter an infinite loop, consuming excessive CPU resources. Repeated exploitation can lea...

CVE-2026-80704

A flaw was found in the Linux kernel's drm/amd/display component. This vulnerability arises from the improper use of an uninitialized logging context, which can lead to a NULL pointer dereference. A local attacker could potentially trigger this flaw, causing the system to crash and resulting in a...

CVE-2026-80698

A flaw was found in the dmaengine: idxd component of the Linux kernel. This vulnerability is caused by a double free error where memory allocated for work queue wq, engine, and group structures is freed twice. This occurs because kfree is explicitly called in error handling and cleanup routines, ...

CVE-2026-80716

A flaw was found in the Linux kernel. Specifically, in the Advanced Linux Sound Architecture ALSA Pulse-Code Modulation PCM subsystem, a use-after-free vulnerability exists. This occurs when a linked stream is unlinked, and a wait entry is not properly removed from the drained peer's sleep list. ...

CVE-2026-80715

A flaw was found in the Linux kernel's igc network driver. When an application using AFXDP, a high-performance network data path, is abruptly terminated, a synchronization issue can occur. This prevents the network interface from properly shutting down. A local attacker could exploit this to caus...

CVE-2026-80699

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM component for ARM64 architectures. This vulnerability, specifically affecting AmpereOne processors, occurs when a physical interrupt is double-deactivated in a nested virtualization context. An attacker could potentially...

CVE-2026-80686

A flaw was found in the Linux kernel's memory management component. Specifically, the migratedevice functionality may attempt to access memory page table entries PTEs that are not present. This incorrect handling can lead to system instability, potentially causing a system crash Denial of Service...

CVE-2026-80657

A flaw was found in the Linux kernel's accel/amdxdna component. The management mailbox channel cleanup helpers, xdnamailboxfreechannel and xdnamailboxstopchannel, could be called from error handling paths when the mgmtchann was already destroyed. This could lead to a NULL pointer dereference,...

CVE-2026-80638

A flaw was found in the ocfs2 component of the Linux kernel. When a user unlinks a refcounted file whose refcount tree has leaf blocks, an out-of-bounds write occurs within the ocfs2removerefcountextent function. This happens because a memset operation writes past the intended memory boundary due...

CVE-2026-40015

A flaw was found in Dovecot's imap-hibernate service. An authenticated attacker can open numerous connections and send malformed commands, leading to an out-of-bounds read. This can intermittently crash the process, interrupting hibernated IMAP sessions and causing a denial of service for affecte...

CVE-2026-40014

A flaw was found in Dovecot. A remote attacker, by sending a specially crafted email message header to a user, can cause the Internet Message Access Protocol IMAP THREAD command to consume excessive CPU resources. When a mail client processes this message, it can lead to degradation or a denial o...

CVE-2026-40013

A flaw was found in Dovecot. An authenticated attacker can submit a specially crafted Sieve script containing an extreme numeric literal to the ManageSieve service. This action triggers an out-of-bounds write during script compilation, leading to memory corruption and a crash of the ManageSieve...

CVE-2026-33607

A flaw was found in Dovecot. An authenticated attacker can exploit a vulnerability in the IMAP LIST command to consume excessive CPU resources. This can lead to a degradation of service or a complete denial of service DoS for the IMAP server, impacting the availability of email services. Mitigati...

CVE-2026-33605

A flaw was found in Dovecot. An unauthenticated attacker can crash the ManageSieve login process by sending a small malformed command before authenticating. This can lead to a denial of service for Sieve script management, affecting either the attacker's connection or all connections handled by t...
