Affected: Linux

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

arm64/fpsimd: signal: Allocate SSVE storage when restoring ZA

The code to restore a ZA context doesn't attempt to allocate the task's sve_state before setting TIF_SME. Consequently, restoring a ZA context can place a task into an invalid state where TIF_SME is set but the task's sve_state is NULL.

In legitimate but uncommon cases where the ZA signal context was NOT created by the kernel in the context of the same task (e.g. if the task is saved/restored with something like CRIU), we have no guarantee that sve_state had been allocated previously. In these cases, userspace can enter streaming mode without trapping while sve_state is NULL, causing a later NULL pointer dereference when the kernel attempts to store the register state:

It was discovered that the Linux kernel algif_aead module did not properly handle in-place cryptographic operations. This flaw is known as Copy Fail. A local attacker could use this to escalate privileges, or possibly escape a container. (CVE-2026-31431)

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; - x86 architecture; - Cryptographic API; - Compute Acceleration Framework; - Drivers core; - Null block device driver; - Ublk userspace block driver; - Bluetooth drivers; - Counter interface drivers; - DMA engine subsystem; - DPLL subsystem; - GPU drivers; - HID subsystem; - Intel Trace Hub HW tracing drivers; - IIO ADC drivers; - IIO subsystem; - On-Chip Interconnect management framework; - IRQ chip drivers; - Modular ISDN driver; - LED subsystem; - Multiple devices driver; - UACCE accelerator framework; - MMC subsystem; - Ethernet bonding driver; - Network drivers; - Mellanox network drivers; - NVME drivers; - PHY drivers; - x86 platform drivers; - i.MX PM domains; - SCSI subsystem; - SLIMbus drivers; - SPI subsystem; - TCM subsystem; - W1 Dallas's 1-wire bus driver; - Xen hypervisor drivers; - BTRFS file system; - EFI Variable file system; - exFAT file system; - Ext4 file system; - HFS+ file system; - Network file system (NFS) client; - N…
