CVE-2026-64263

A flaw was found in the Linux kernel's fuse-uring component. This vulnerability arises from the incorrect handling of cancelled entries, which are moved to a list where a subsequent operation unconditionally attempts to access a null pointer. A local attacker could exploit this flaw to trigger a...

CVE-2026-64257

A flaw was found in the Linux kernel's Server Message Block SMB client. A remote attacker could exploit a vulnerability where the client improperly handles SMB2 responses containing overlapping data areas. This incorrect processing of malformed network data could lead to a denial of service DoS o...

CVE-2026-64506

A flaw was found in the Realtek 802.11ac wireless driver rtw89 within the Linux kernel. A remote attacker, within adjacent network range, could send specially crafted malformed Aggregated MAC Protocol Data Unit AMPDU frames. This incorrect handling of frames, particularly during rekey processes,...

CVE-2026-64522

A flaw was found in the Linux kernel's mlx5e network driver. When handling temporary Security Associations SAs for IPsec, the mlx5exfrmaddstate function incorrectly decrements a counter without a corresponding increment. This underflow in the eswitch mode block mechanism can lead to a denial of...

CVE-2026-64410

A flaw was found in the Linux kernel's netfilter component, specifically concerning the handling of IPIP IP-in-IP tunnel hardware offload. The system attempts to utilize hardware offload for IPIP tunnels, a feature not yet supported by existing drivers. A remote attacker could potentially exploit...

CVE-2026-64436

A flaw was found in the Linux kernel. An uninitialized variable in the IPComp IP Compression state handling could allow a local attacker to trigger an out-of-bounds read during state migration. This vulnerability could lead to the disclosure of sensitive kernel memory or cause a denial of service...

CVE-2026-64518

A flaw was found in the Linux kernel's TCP implementation. An out-of-bounds access vulnerability exists when the lockdepsockisheld function is called with a tcptimewaitsock object. This occurs because the tcptimewaitsock object lacks the necessary sk-sklock, leading to an incorrect lockdep...

CVE-2026-64344

A flaw was found in the Linux kernel's USB idmouse driver. A local attacker could exploit a use-after-free vulnerability due to a race condition that occurs when a USB idmouse device is disconnected. This race condition allows mutexunlock to access freed memory, which can lead to a system crash a...

CVE-2026-64302

A flaw was found in the Linux kernel. A local user could exploit an issue in the pagetablefree function, which incorrectly handles vmemmap pages. This improper memory management leads to a memory leak, where only a portion of the allocated memory is freed. Consequently, this can result in a Denia...

CVE-2026-64375

A flaw was found in the Linux kernel's proc filesystem. A local attacker with low privileges could exploit a race condition within the ptracemayaccess function when handling file descriptor links. This vulnerability arises because the system performs multiple task lookups without proper...

CVE-2026-64461

A flaw was found in the Linux kernel's MediaTek PCIe driver. When a Peripheral Component Interconnect Express PCIe port fails to enable, the associated Interrupt Request IRQ domains are not properly released. This resource leak can accumulate over time, potentially leading to a denial of service...

CVE-2026-64404

A flaw was found in the Linux kernel's Bluetooth subsystem. A race condition exists in the isoconnbigsync function where a socket lock is temporarily released and re-acquired. During this window, the Bluetooth connection can be unexpectedly terminated. If the connection is torn down, the subseque...

CVE-2026-64425

A flaw was found in the Linux kernel's iouring subsystem. This vulnerability allows linked work items to continue executing even after a system exit process has begun. This can lead to a denial of service by prolonging the exit sequence and potentially consuming system resources unexpectedly...

CVE-2026-64491

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture usx2y us144mkii driver. This vulnerability, a Use-After-Free UAF, occurs when a USB device is disconnected, leading to a race condition where the system attempts to access memory that has already been released. This cou...

CVE-2026-64519

A flaw was found in the Linux kernel's Network File System Daemon NFSD. This vulnerability allows a remote attacker to cause a Denial of Service DoS by triggering an infinite loop during layout state revocation. The issue occurs because the system repeatedly attempts to revoke a layout state...

CVE-2026-64376

A flaw was found in the Linux kernel's firmware loader component. This vulnerability occurs in the firmwareuploadregister function when an allocation failure happens after a device instance is created. The system fails to properly release a device reference, leading to an unbalanced reference...

CVE-2026-64454

A flaw was found in the Linux kernel's USB dwc3 driver. A local attacker could trigger a condition where a sleeping function is called from an invalid context during a USB gadget suspend operation. This can lead to system instability or a kernel panic, resulting in a Denial of Service DoS...

CVE-2026-64472

A flaw was found in the Linux kernel's vfio/mlx5 subsystem. This vulnerability arises from non-atomic bitfield operations, where multiple updates to shared data structures can occur concurrently. This race condition may lead to unexpected behavior or data corruption due to inconsistent state,...

CVE-2026-64338

A flaw was found in the Linux kernel's uss720 driver. When the uss720probe function attempts to initialize a USB parallel port parport device, it registers the parport but may fail to unregister it if a subsequent hardware register read operation fails. This improper resource management leaves a...

CVE-2026-64298

A flaw was found in the Linux kernel's NFSv4 implementation. A local user could exploit a vulnerability where opening a file with OTRUNC truncate and ORDONLY read-only flags would bypass the necessary write permission checks. This oversight allows an attacker to truncate a file without having...
