CVE-2026-80551

A flaw was found in the Linux kernel's s390/vfioccw component. This vulnerability arises because the system does not ensure that the address in the first Indirect Data Address Word IDAW remains constant between reads. An attacker could potentially exploit this to cause the system to operate with ...

kernel: net: ipv6: use-after-free in fib6_rule_suppress due to stale res->rt6 pointer

A use-after-free vulnerability was found in the Linux kernel's IPv6 FIB rule lookup path. In fib6rulesuppress, when a route is suppressed and released via ip6rtputflags, the res-rt6 pointer is not cleared. If no later rule supplies a replacement route, fib6rulelookup returns the stale freed rt6in...

CVE-2026-80589

A flaw was found in the Linux kernel's block subsystem. This vulnerability occurs when a disk's initialization fails before it is fully integrated, causing a critical timer to remain active even after the associated memory is released. This improper handling of memory can lead to a use-after-free...

CVE-2026-80570

A flaw was found in the synaptics-rmi4 component of the Linux kernel. This vulnerability occurs when an error in processing a report request or command leads to an incorrect size being used for subsequent data operations. A local user could exploit this by manipulating the video format, causing t...

CVE-2026-80556

A flaw was found in the Linux kernel's atmel-mci component. A race condition during the removal of the atmel-mci module can lead to a use-after-free vulnerability. This occurs when work items related to the module are still pending or running after the associated memory has been freed. This flaw...

CVE-2026-80528

A flaw was found in the Linux kernel's Ceph filesystem. When the kernel handles replies and fills inode and dentry caches, a memory allocation can trigger a memory reclamation process. This process can incorrectly interpret Ceph-specific data as a journal handle if it interacts with another...

CVE-2026-80526

A flaw was found in the Linux kernel's ASoC Audio System on Chip tas2562 driver. The tas2562volumecontrolput function lacks proper validation of control values provided by userspace. A local attacker could exploit this by supplying a specially crafted value, leading to an array overflow and an...

CVE-2026-80587

A flaw was found in the Multipath TCP MPTCP implementation within the Linux kernel. This vulnerability arises from the kernel's handling of mutually exclusive MPTCP suboptions. A remote attacker could send specially crafted MPTCP suboptions that, when combined, are not expected by the kernel. Thi...

CVE-2026-80544

A flaw was found in the Linux kernel's s390/zcrypt component. The zcryptmsgtype6sendep11cprb function, responsible for handling EP11 CPRB Coprocessor Request Block domains, uses fragile struct overlays. This approach lacks proper ASN.1 Abstract Syntax Notation One encoding validation and bounds...

CVE-2026-80542

A flaw was found in the drm/amd/display component of the Linux kernel. The amdgpudmcrtcsetvblank function attempts to dereference a NULL pointer when vblank is enabled or queried before a display stream is properly attached. This can be triggered by a local attacker running specific graphics test...

kernel: net: ipv6: use-after-free in fib6_rule_suppress due to stale res->rt6 pointer

A use-after-free vulnerability was found in the Linux kernel's IPv6 FIB rule lookup path. In fib6rulesuppress, when a route is suppressed and released via ip6rtputflags, the res-rt6 pointer is not cleared. If no later rule supplies a replacement route, fib6rulelookup returns the stale freed rt6in...

CVE-2026-80519

A flaw was found in the Linux kernel. Specifically, within the OpenVPN OVPN module's crypto completion callback mechanism, a timing issue exists. This vulnerability arises when peer references are released prematurely, before the associated cleanup operations are complete. An attacker could...

CVE-2026-80568

A flaw was found in the Linux kernel's synaptics-rmi4 input driver. Changing the diagnostic report type while a video stream V4L2 is active can alter the expected report size. Since V4L2 buffers are allocated based on the initial size at stream start, a larger subsequent report could lead to a he...

kernel: net: ipv6: use-after-free in fib6_rule_suppress due to stale res->rt6 pointer

A use-after-free vulnerability was found in the Linux kernel's IPv6 FIB rule lookup path. In fib6rulesuppress, when a route is suppressed and released via ip6rtputflags, the res-rt6 pointer is not cleared. If no later rule supplies a replacement route, fib6rulelookup returns the stale freed rt6in...

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...
