Attila Szász discovered that the HFS+ file system implementation in the Linux Kernel contained a heap overflow vulnerability. An attacker could use a specially crafted file system image that, when mounted, could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2025-0927)

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; - Block layer subsystem; - ACPI drivers; - Drivers core; - ATA over ethernet (AOE) driver; - TPM device driver; - GPIO subsystem; - GPU drivers; - HID subsystem; - I2C subsystem; - InfiniBand drivers; - Mailbox framework; - Multiple devices driver; - Media drivers; - Network drivers; - NTB driver; - Virtio pmem driver; - Parport drivers; - PCI subsystem; - SPI subsystem; - Direct Digital Synthesis drivers; - USB Device Class drivers; - USB Dual Role (OTG-ready) Controller drivers; - USB Serial drivers; - USB Type-C support driver; - Framebuffer layer; - BTRFS file system; - Ceph distributed file system; - Ext4 file system; - F2FS file system; - File systems infrastructure; - JFS file system; - Network file system (NFS) client; - Network file system (NFS) server daemon; - NILFS2 file system; - SMB network file system; - Network traffic control; - Network sockets; - TCP network protocol; - BPF subsys…
