CVE-2026-90012

A flaw was found in the Linux kernel's Serial Peripheral Interface SPI subsystem. When handling Direct Memory Access DMA mappings, an issue arises if a receive RX mapping fails after a transmit TX mapping succeeds, or if a TX mapping fails during a subsequent transfer. This can lead to incorrect...

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.
