Affected: Linux

In the Linux kernel, the following vulnerability has been resolved:

ASoC: Intel: avs: Disable periods-elapsed work when closing PCM

avs_dai_fe_shutdown() handles the shutdown procedure for HOST HDAudio stream while period-elapsed work services its IRQs. As the former frees the DAI's private context, these two operations shall be synchronized to avoid slab-use-after-free or worse errors.

Affected: Ubuntu:25.10: linux, Ubuntu:25.10: linux-raspi, Ubuntu:25.10: linux-realtime

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; - MIPS architecture; - Nios II architecture; - PA-RISC architecture; - RISC-V architecture; - S390 architecture; - Sun Sparc architecture; - x86 architecture; - Xtensa architecture; - Block layer subsystem; - Cryptographic API; - Compute Acceleration Framework; - ACPI drivers; - Drivers core; - Network block device driver; - Bluetooth drivers; - Bus devices; - Hardware random number generator core; - Character device driver; - Clock framework and drivers; - Data acquisition framework and drivers; - CPU frequency scaling framework; - Hardware crypto device drivers; - CXL (Compute Express Link) drivers; - Device frequency scaling framework; - ARM SCMI message protocol; - GPIO subsystem; - GPU drivers; - Hardware monitoring drivers; - HW tracing; - InfiniBand drivers; - Input Device (Miscellaneous) drivers; - IOMMU subsystem; - ISDN/mISDN subsystem; - Mailbox framework; - Multiple devices driver; - Media drivers; - Fastrpc Driver; - PCI Endpoint Test driver; - VMware Balloon Driver; - MOST (Media Oriented Systems Transport) drivers; - Network drivers; - Mellanox network drivers; - STMicroelectronics network drivers; - NVME drivers; - PCI subsystem; - Performance monitor drivers; - Pin…
