USN-8781-1: Linux kernel (NVIDIA Tegra) vulnerabilities

It was discovered that some Arm processors could complete a broadcast translation lookaside buffer (TLB) invalidation before memory writes made through the invalidated translation were globally observed. A local attacker could possibly use this to write to memory after permission to do so had been revoked, bypassing memory protections or escalating privileges. (CVE-2025-10263) Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - ARM64 architecture; - User-space API (UAPI); - Kernel build system; - ARM32 architecture; - PowerPC architecture; - RISC-V architecture; - S390 architecture; - User-Mode Linux (UML); - x86 architecture; - Cryptographic API; - Intel NPU Driver; - Compute Acceleration Framework; - ACPI drivers; - Drivers core; - DRBD Distributed Replicated Block Device drivers; - Rados block device (RBD) driver; - Ublk userspace block driver; - Compressed RAM block device driver; - Bluetooth drivers; - Hardware crypto device drivers; - CXL (Compute Express Link) drivers; - Arm Firmware Framework for ARMv8-A(FFA); - EFI core; - FPGA Framework; - GPU drivers; - HID subsystem; - Hardware monitoring drivers; - I2C subsystem; - I3C subsystem; - InfiniBand drivers; - Input Device core drivers; - Input Device (Mouse) drivers; - IOMMU subsystem; - Multiple devices driver; - Media drivers; - Fastrpc Driver; - Network drivers; - Mellanox network drivers; - Microsoft Azure Network Adapter (MANA) driver; - MediaTek network drivers; - NVME drivers; - Operating Performance Points (OPP) driver; - PCI subsystem; - PTP clock framework; - RPMSG subsystem; - SCSI subsystem; - SoundWire subsystem; - SPI subsystem; - Greybus lights staging drivers; - Media staging drivers; - NVIDIA Tegra embedded controller (NVEC) staging driver; - Realtek RTL8723BS SDIO drivers; - TCM subsystem; - Trusted Execution Environment drivers; - Thunderbolt and USB4 drivers; - TTY drivers; - USB Gadget drivers; - USB Dual Role (OTG-ready) Controller drivers; - USB Serial drivers; - vDPA drivers; - VFIO drivers; - Virtio Host (VHOST) subsystem; - Virtio drivers; - Xen hypervisor drivers; - 9P distributed file system; - AFS file system; - File systems infrastructure; - BTRFS file system; - Ceph distributed file system; - exFAT file system; - F2FS file system; - GFS2 file
