CVE-2026-90066

A flaw was found in the Linux kernel's ftrace module. This vulnerability occurs because the ftracedirectmultiinit function does not properly check the return value of kthreadrun. If kthreadrun fails, an error pointer is assigned, which is later passed to kthreadstop during module unload. This...

CVE-2026-90064

A flaw was found in the Linux kernel. Specifically, within the drm/xe driver, a vulnerability exists where a virtual machine VM not configured for fault handling attempts to process a page fault on an already valid virtual memory area VMA. This can lead to the Graphics Processing Unit GPU enterin...

CVE-2026-90062

A flaw was found in the Linux kernel's netfilter subsystem, specifically within the nftables component. This vulnerability occurs because the hardware offload step for network filtering rules is performed before the complete set of rules chain blob is built. This timing issue can lead to an...

CVE-2026-90060

A flaw was found in the Linux kernel's ALSA control module. A local user could create a write-only kcontrol element without a get callback. This could lead to a null pointer dereference in the LED layer, causing a system crash and resulting in a denial of service...

CVE-2026-90058

A flaw was found in the Linux kernel's networking scheduler net/sched. A local unprivileged user with CAPNETADMIN capabilities within a user namespace could provide a crafted size table to a deficit scheduler, such as DRR or ETS, with a small quantum. This manipulation can cause the scheduler to...

CVE-2026-90140

A flaw was found in the Linux kernel's cuse module. This vulnerability, a Use-After-Free, occurs when the cuse module is unloaded before a pending Read-Copy-Update RCU callback has completed. This can lead to a system crash or, under specific circumstances, allow a local attacker to execute...

CVE-2026-90137

A flaw was found in the Linux kernel's hp-bioscfg component. The password encoding parser, specifically the PSWDENCODINGS parser, does not adequately validate the number of entries when processing an ACPI Advanced Configuration and Power Interface package. A malformed ACPI package can cause the...

CVE-2026-90134

A flaw was found in the Linux kernel's NTFS filesystem driver. This vulnerability arises from incorrect handling of memory page mappings in compressed input/output I/O operations. An attacker could potentially exploit this flaw by interacting with the NTFS driver, leading to system instability or...

CVE-2026-90133

A flaw was found in the Linux kernel's NTFS filesystem driver. The ntfsirtoib function fails to validate the size of entries when copying them from an index root into a buffer. This oversight allows a local attacker, by mounting a specially crafted NTFS filesystem image, to trigger a heap...

CVE-2026-90132

A flaw was found in the Linux kernel's NTFS filesystem. This vulnerability allows an unprivileged local user to bypass intended access controls by modifying reserved extended attributes xattrs, such as $LXUID, $LXGID, $LXMOD, and $LXDEV, through the setxattr function. This unauthorized modificati...

CVE-2026-90131

A flaw was found in the Linux kernel's NTFS filesystem driver. A local attacker could exploit a data race condition between concurrent read and write operations on resident iomap data. This race allows a reader to observe inconsistent attribute length and offset fields, potentially leading to dat...

CVE-2026-90128

A flaw was found in the Linux kernel's vdpa/mlx5 driver. An error in the adddirectchain function's cleanup path causes the system to iterate over an incorrect list. This could lead to improper memory handling during error conditions, potentially resulting in system instability or a denial of...

CVE-2026-90127

A flaw was found in the Linux kernel's virtio-rtc driver. This vulnerability occurs because alarm requests lack a timeout. A local attacker could exploit this by triggering a surprise removal of a virtio device while an alarm request is pending. This action causes the device removal process to ha...

CVE-2026-90124

A flaw was found in the Linux kernel's interrupt handling for Renesas RZ/G2L devices. A race condition in the interrupt clearing mechanism can occur when multiple interrupts are triggered concurrently. This can lead to the premature clearing and loss of an unserviced interrupt. The consequence is...

CVE-2026-90122

A flaw was found in the Linux kernel's Visconti clock driver. The clkinitdata structure, which manages clock parent data, may not be fully initialized. This uninitialized data can lead to a system crash when the visconticlkregistergate function is called under specific kernel configurations. This...

CVE-2026-90121

A flaw was found in the Linux kernel's irqchip/gic-v5 component. During the setup or teardown of Interrupt Routing System IRS affinity, the system may fail to properly clear pointers to freed memory. This can result in central processing units CPUs attempting to access memory that has already bee...

CVE-2026-90123

A flaw was found in the Linux kernel's irqchip/ast2700-intc component. An invalid memory allocation attempt occurs within the irqdomainactivate callback while interrupts are disabled and a spinlock is held. This condition, triggered by the fwnodedeviceiscompatible function, can lead to system...

CVE-2026-90120

A flaw was found in the Linux kernel's GIC-v5 interrupt controller component. The gicacpiparseiaffid function does not properly validate the return value from getlogicalindex. This can lead to out-of-bounds memory corruption when processing Advanced Configuration and Power Interface ACPI data,...

CVE-2026-90118

A flaw was found in the Linux kernel's NTFS filesystem driver. An off-by-one error in the ntfsdecompress function, when processing a specially crafted compressed data attribute, can lead to out-of-bounds writes. This could result in memory corruption, potentially allowing a local attacker to...
