Affected: Linux

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

svcrdma: fix miss destroy percpu_counter in svc_rdma_proc_init()

There's issue as follows: RPC: Registered rdma transport module. RPC: Registered rdma backchannel transport module. RPC: Unregistered rdma transport module. RPC: Unregistered rdma backchannel transport module.

If register_sysctl() return NULL, then svc_rdma_proc_cleanup() will not destroy the percpu counters which init in svc_rdma_proc_init(). If CONFIG_HOTPLUG_CPU is enabled, residual nodes may be in the 'percpu_counters' list. The above issue may occur once the module is removed. If the CONFIG_HOTPLUG_CPU configuration is not enabled, memory leakage occurs. To solve above issue just destroy all percpu counters when register_sysctl() return NULL.

Affected: Ubuntu:24.10: linux, Ubuntu:24.10: linux-lowlatency

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: - ARM32 architecture; - ARM64 architecture; - PowerPC architecture; - RISC-V architecture; - S390 architecture; - SuperH RISC architecture; - User-Mode Linux (UML); - x86 architecture; - Block layer subsystem; - Cryptographic API; - Compute Acceleration Framework; - ACPI drivers; - Drivers core; - ATA over ethernet (AOE) driver; - RAM backed block device driver; - Network block device driver; - Ublk userspace block driver; - Compressed RAM block device driver; - Bluetooth drivers; - TPM device driver; - Clock framework and drivers; - Data acquisition framework and drivers; - CPU frequency scaling framework; - Hardware crypto device drivers; - CXL (Compute Express Link) drivers; - DAX dirext access to differentiated memory framework; - Buffer Sharing and Synchronization framework; - EDAC drivers; - FireWire subsystem; - ARM SCMI message protocol; - ARM SCPI message protocol; - EFI core; - Qualcomm firmware drivers; - GPIO subsystem;…
