CVE-2026-80564

A flaw was found in the Linux kernel's gve component. A local user can trigger a NULL pointer dereference by attempting to use the ptp adjfine function, which has a missing implementation. This vulnerability can lead to a system crash, resulting in a Denial of Service DoS...

CVE-2026-80540

A flaw was found in the Linux kernel's drm/amdgpu component, specifically within the Universal Video Decoder UVD image size calculation. This vulnerability occurs because the minimum image size calculation incorrectly uses width instead of pitch and fails to reject pitch values exceeding 4096. An...

CVE-2026-74735

A flaw was found in the Linux kernel's L2TP Layer 2 Tunneling Protocol implementation. A local user could trigger a reference count leak by closing specific /proc or /sys files related to L2TP tunnels and sessions before fully reading their content. This could lead to resource exhaustion,...

CVE-2026-80563

A flaw was found in the Linux kernel's gpio: sloppy-logic-analyzer component. A local attacker with root privileges can exploit a race condition during the unbinding of a platform device. This vulnerability allows writing into memory that has already been freed, which can lead to system instabili...

CVE-2026-74746

A flaw was found in the netfilter flowtable component of the Linux kernel. This vulnerability occurs due to a timing issue where the system's garbage collection can free a network flow while it is still being set up. This can lead to a 'use-after-free' condition, where the system attempts to acce...

CVE-2026-80583

A flaw was found in the Linux kernel, specifically within the lpass-tx-macro audio codec driver. This vulnerability arises from the driver's incorrect handling of certain control values, where it uses an improper data type for accessing enumerated kernel controls. This error can lead to a system...

CVE-2026-80573

A flaw was found in the Linux kernel's iforce driver, which handles input devices such as joysticks and wheels. This vulnerability occurs because the iforceprocesspacket function processes incoming data packets without adequately validating their lengths. A local attacker could exploit this by...

CVE-2026-74747

A flaw was found in the Linux kernel's IP Virtual Server IPVS component. A local attacker can manipulate the IP Header Length ihl field within network packets. This manipulation can lead to an out-of-bounds access when the kernel attempts to revalidate embedded headers, potentially causing system...

CVE-2026-74741

A flaw was found in the Linux kernel's ngbe network driver. In systems configured for non-MSI-X interrupt handling, such as legacy INTx or single MSI modes, a missing initialization of a pointer can lead to a NULL pointer dereference. This vulnerability can cause the system to crash, resulting in...

CVE-2026-80578

A flaw was found in the Linux kernel's fbdev core. A local user could trigger an out-of-bounds read vulnerability in the fbioread function. This occurs due to a pointer desynchronization when handling partial copies from a faulty user buffer, allowing the system to read beyond intended memory...

CVE-2026-80521

A flaw was found in the Linux kernel's afunix component. A race condition during concurrent send and close operations can lead to the garbage collector GC partially freeing a Strongly Connected Component SCC. This inconsistent state may cause subsequent GC operations to iterate over a partially...

CVE-2026-74737

A flaw was found in the Linux kernel's am65-cpsw-nuss Ethernet driver. When processing incoming network packets, the driver incorrectly extracts the MAC Port ID from the Source Tag, using 16 bits instead of the intended lower 8 bits. This error can lead to the driver accessing out-of-bound memory...

CVE-2026-80584

A flaw was found in the Linux kernel's s390/qeth component. This vulnerability allows a local attacker to trigger an integer underflow when handling user-supplied buffer lengths in the qethsnmpcommand and qethl3arpquery functions. This can lead to an out-of-bounds write, potentially causing memor...

CVE-2026-74740

A flaw was found in the Linux kernel's network scheduler net/sched: actapi. A Time-of-Check to Time-of-Use TOCTOU race condition exists where a pointer can be cleared between two reads. This allows a concurrent operation to cause a NULL dereference, potentially leading to a system crash and Denia...

CVE-2026-80572

A flaw was found in the Linux kernel's byd input driver. A race condition exists during device disconnection where the byddisconnect function frees private data before ensuring that a timer callback, bydcleartouch, has completed. This can lead to the callback attempting to access memory after it...

CVE-2026-80520

A flaw was found in the ovpn module of the Linux kernel. The ovpncryptokillkey function incorrectly assumes that both crypto key slots are always populated. This can lead to a NULL dereference if a peer has only one installed key or if the function attempts to remove a key that is not present. A...

CVE-2026-80582

A flaw was found in the Linux kernel's drm/shmemhelper component. This vulnerability arises from insufficient boundary checks when handling large memory pages. An attacker could potentially trigger an attempt to map memory outside its designated area. This improper memory handling could lead to a...

CVE-2026-80569

A flaw was found in the synaptics-rmi4 driver within the Linux kernel. A malicious or malfunctioning RMI4 device can exploit this vulnerability by reporting incorrect electrode counts. This leads to the driver attempting to write data beyond the allocated memory buffer, causing memory corruption...

CVE-2026-80565

A flaw was found in the Linux kernel's crypto: qce component. An error in the devmqceregisteralgs function's error handling path causes the system to repeatedly attempt to unregister algorithms incorrectly when a registration fails. This improper handling of resources could lead to system...
