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; - Network file system (NFS) server daemon; - NTFS3 file system; - SMB network file system; - Scheduler infrastructure; - Netfilter; - NFC subsystem; - Tracing infrastructure; - io_uring subsystem; - BPF subsystem; - Perf events; - Floating proportions library; - Memory management; - Bluetooth subsystem; - CAN network layer; - Ceph Core library; - Networking core; - IPv4 networking; - IPv6 networking; - L2TP protocol; - MAC80211 subsystem; - NET/ROM layer; - Packet sockets; - Network traffic control; - SCTP protocol; - TLS protocol; - Unix domain sockets; - VMware vSockets driver; - Wi
