CVE-2026-63942

A flaw was found in the Linux kernel's parallel port parport subsystem. This vulnerability is caused by a race condition where parallel port devices are registered before they are fully initialized. This allows client drivers to interact with uninitialized or unstable ports, which can lead to a...

CVE-2026-63940

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM Secure Encrypted Virtualization SEV module. This vulnerability occurs because the system does not properly handle Port I/O requests with a length of zero. An attacker, potentially from a guest virtual machine, could exploit...

CVE-2026-63938

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM Secure Encrypted Virtualization SEV feature. When processing Page State Change PSC requests, the system does not properly validate the PSC buffer against the effective size of the scratch area. This can occur if a guest...

CVE-2026-63939

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM with Secure Encrypted Virtualization SEV support. This vulnerability arises from an incorrect calculation of the maximum length for the in-Guest-Host Communication Block GHCB scratch area. When processing Page State Change PS...

CVE-2026-63937

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM with Secure Encrypted Virtualization SEV. This time-of-check to time-of-use TOCTOU vulnerability exists when KVM processes the guest-accessible Page State Change PSC buffer. A misbehaving guest could exploit this timing issue...

CVE-2026-63934

A flaw was found in the Linux kernel's iioitg3200 gyroscope driver. An incorrect I2C Inter-Integrated Circuit read operation in the itg3200readallchannels function causes uninitialized stack memory to be exposed to userspace. This information leak could allow a local attacker to gain access to...

CVE-2026-63936

A flaw was found in the Linux kernel's MediaTek MT6359 Analog-to-Digital Converter ADC driver. The mt6358readimp function does not properly check the return value of a read operation. If the read fails, an uninitialized variable is used, which can lead to the leakage of sensitive information from...

CVE-2026-63932

A flaw was found in the Linux kernel's mhz19b driver, which handles Winsen MHZ19B CO2 sensors. The mhz19breceivebuf function does not properly validate the size of incoming serial replies before copying them into a fixed-size buffer. A remote attacker could exploit this by sending an oversized...

CVE-2026-63931

A flaw was found in the Linux kernel's iio: chemical: scd30 driver. A local user can trigger a denial of service DoS by writing a zero fractional part to the samplingfrequency sysfs attribute. This action leads to a division-by-zero error within the kernel, causing the system to crash...

CVE-2026-63926

A flaw was found in the Linux kernel's sockmap feature. When the bpfmsgpushdata function processes data, it incorrectly calculates the offset for data fragments, leading to an inconsistent memory arrangement. This issue could potentially allow a local attacker to cause data corruption or system...

CVE-2026-63927

A flaw was found in the Linux kernel, specifically within the dwc2 USB driver. This vulnerability, known as a use-after-free, occurs when the system attempts to access memory that has already been released. This happens because a USB Request Block urb is incorrectly accessed after it has been...

CVE-2026-63925

A flaw was found in the Linux kernel's MACsec Media Access Control Security subsystem. When using Extended Packet Numbering XPN, a vulnerability exists where the replay protection mechanism can be bypassed. An attacker can exploit an integer overflow when the packet number reaches its maximum...

CVE-2026-63920

A flaw was found in the Linux kernel's IPv6 networking stack. An unprivileged local user could exploit a vulnerability in how IPv6 extension header lengths are handled. By manipulating these headers using nftables, an attacker can trigger an out-of-bounds read, leading to information disclosure...

CVE-2026-63919

A flaw was found in the Linux kernel's xfrm input component. The transport-mode reinjection process, which handles network packet re-injection, stores a network namespace pointer that must remain valid until a deferred callback completes. However, a missing reference count for the network namespa...

CVE-2026-63923

A flaw was found in the Linux kernel's octeontx2-af driver. A malicious Virtual Function VF attached to a Physical Function PF in switchdev representor mode can send a specially crafted REPEVENTNOTIFY message. This message contains an unvalidated pcifunc field, which can lead to an out-of-bounds...

CVE-2026-63921

A flaw was found in the Linux kernel's IPv6 Virtual Tunnel Interface VTI module. When a VTI tunnel device is moved to a different network environment, an unprivileged user in a separate user space can manipulate tunnel parameters. This manipulation could allow the user to intercept or redirect...

CVE-2026-63922

A flaw was found in the Linux kernel's IPv6 extension header processing. When processing the Home Address Option HAO, the cached network header pointer may become invalid if the packet's memory is reallocated. This can lead to incorrect parsing of subsequent IPv6 Type-Length-Value TLV options,...

CVE-2026-63918

A flaw was found in the Linux kernel's Layer 2 Tunneling Protocol l2tp module. A race condition exists where a network session's memory could be prematurely released while still in use. This vulnerability, caused by incorrect reference counting, may allow a local attacker to trigger a system cras...

CVE-2026-63911

A flaw was found in the Linux kernel's xfrm: iptfs component. This vulnerability arises from incorrect handling of runtime data when cloning Security Associations SAs. If a state migration fails, the cloned state can improperly share memory with the original, leading to use-after-free and...

CVE-2026-63908

A flaw was found in the Linux kernel's atmelmxtts input driver. An incorrect boundary check when handling configuration files with oversized objects can lead to a single-byte overwrite in adjacent memory. This memory corruption vulnerability could allow a local attacker to potentially cause syste...
