CVE-2026-98636

A flaw was found in the SquashFS file system implementation in the Linux kernel. A local user could exploit this vulnerability by mounting a specially crafted SquashFS image with an invalid dictionary size. Processing this image triggers an invalid shift operation, leading to a kernel crash and...

CVE-2026-98637

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine subsystem for ARM64. When a virtual CPU vCPU fails to initialize Scalable Vector Extension SVE support, feature flags are improperly handled, leaving subsequent vCPUs in an inconsistent state without allocated memory. A guest...

CVE-2026-80752

A flaw was found in the Linux kernel's psxpad-spi driver. This vulnerability occurs because the psxpadspisuspend function attempts to access controller state before it has been properly initialized, leading to a null pointer dereference. A local attacker could exploit this to cause a system crash...

CVE-2026-80743

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture System on Chip ASoC xilinx formatterpcm component. This vulnerability arises when interrupt request IRQ handlers attempt to access driver data before it has been fully initialized during device setup. An interrupt occurring ...

CVE-2026-98638

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine subsystem on ARM64 systems. This vulnerability can lead to a Denial of Service DoS by causing a fatal hypervisor crash. The Protected KVM pKVM hypervisor does not properly validate the Scalable Vector Extension SVE vector...

K000163825: Linux kernel vulnerabilities CVE-2026-46110 and CVE-2026-46115

Security Advisory Description CVE-2026-46110 In the Linux kernel, the following vulnerability has been resolved: net: stmmac: Prevent NULL deref when RX memory exhausted The CPU receives frames from the MAC through conventional DMA: the CPU allocates buffers for the MAC, then the MAC fills them a...

CVE-2026-98634

A flaw was found in the Linux kernel's SCSI ZBC Zoned Block Commands driver. This vulnerability can lead to a denial of service DoS when the system attempts to scan a storage device that reports an excessively large number of zones. Due to integer truncation and overflow during zone calculations,...

CVE-2026-98635

A flaw was found in the Linux kernel. An attacker who attaches a specially crafted storage device can cause a Denial of Service DoS or kernel memory corruption. When the kernel revalidates zoned block devices—storage media divided into independent physical regions—it fails to verify that the...

CVE-2026-90024

A flaw was found in the Linux kernel's USB MIDI 2.0 gadget function. When the MIDI 2.0 gadget is configured with a specific input block direction, an endpoint may not be properly initialized. During subsequent endpoint cleanup, an attempt to access this uninitialized endpoint can lead to a...

CVE-2026-89780

A flaw was found in the Qualcomm rmnet driver of the Linux kernel. An unprivileged local user can exploit this vulnerability by manipulating network namespaces and rmnet link configurations. This can lead to a null-pointer dereference when processing deaggregated frames, causing a kernel panic an...

CVE-2026-80846

A flaw was found in the Linux kernel's xfrm subsystem, which handles ESP-in-TCP packets. When queued ESP-in-TCP data is processed after its ingress network device has been removed, the system attempts to dereference a null pointer. This can lead to a system crash, resulting in a Denial of Service...

CVE-2026-80822

A flaw was found in the Linux kernel's mailbox: mchp-ipc-sbi component. This vulnerability arises from a missing null check for a memory allocation function. If the memory allocation fails, it can lead to an error condition, potentially causing a denial of service DoS where the system becomes...

CVE-2026-80819

A flaw was found in the Bluetooth RFCOMM Radio Frequency Communication subsystem of the Linux kernel. A remote attacker can send a specially crafted Bluetooth Disconnect DISC message to a device with a deferred RFCOMM channel. This can lead to a null pointer dereference when the system attempts t...

CVE-2026-80817

A flaw was found in the Linux kernel's iommu/iommufd component. A local user could exploit a race condition during the processing of I/O address space IOAS areas. This vulnerability occurs when iommufdioaschangeprocess attempts to access an IOAS area before its pages are fully mapped, leading to ...

CVE-2026-80816

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA FireWire Control Protocol FCP driver. Incorrect handling of the Universal Serial Bus Request Block URB for the notification endpoint could lead to a system crash. This occurs because the fcpinitnotify function uses a...

CVE-2026-80813

A flaw was found in the Linux kernel's nvmet subsystem. A remote attacker can trigger a NULL pointer dereference in the nvmetexecuteidentifynslist function by issuing a specific Identify command CNS 07h. This vulnerability can lead to a kernel crash, resulting in a Denial of Service DoS for the...

CVE-2026-80771

A flaw was found in the Linux kernel's Nintendo Joy-Con driver. A local attacker could potentially trigger a null pointer dereference by sending a concurrent force-feedback FFRUMBLE command while the device is being registered. This could lead to a system crash, resulting in a Denial of Service D...

CVE-2026-80756

A flaw was found in the SELinux subsystem of the Linux kernel. A local attacker could trigger a null pointer dereference by attempting to load a policy when no old policy exists and the policy conversion fails. This issue, reachable through a write operation to /sys/fs/selinux/load, could lead to...
