This update corrects flaws in the following subsystems: - Foo-over-UDP (FOU); - ARM64 architecture; - x86 architecture; - Block layer subsystem; - Drivers core; - Null block device driver; - Bluetooth drivers; - Counter interface drivers; - DMA engine subsystem; - DPLL subsystem; - GPIO subsystem; - GPU drivers; - I2C subsystem; - IIO ADC drivers; - IIO subsystem; - InfiniBand drivers; - On-Chip Interconnect management framework; - IOMMU subsystem; - IRQ chip drivers; - Modular ISDN driver; - LED subsystem; - Multiple devices driver; - Media drivers; - UACCE accelerator framework; - MMC subsystem; - Ethernet bonding driver; - Network drivers; - Mellanox network drivers; - Texas Instruments network drivers; - NVME drivers; - Device tree and open firmware driver; - PHY drivers; - x86 platform drivers; - i.MX PM domains; - SCSI subsystem; - SLIMbus drivers; - SPI subsystem; - TTY drivers; - USB Host Controller drivers; - W1 Dallas's 1-wire bus driver; - Xen hypervisor drivers; - BTRFS file system; - EFI Variable file system; - File systems infrastructure; - Ext4 file system; - FUSE (File system in Userspace); - Network file systems library; - Network file system (NFS) client; - Network file system (NFS) server daemon; - SMB network file system; - Memory Management; - Memory management; - Scheduler infrastructure; - Tracing infrastructure; - IPv4 networking; - Netfilter; - NFC subsystem; - Network traffic control; - TCP network protocol; - io_uring subsystem; - Perf events; - Locking primitives; - Hibernation control; - Timer subsystem; - BPF subsystem; - Floating proportions library; - Bluetooth subsystem; - CAN network layer; - Ceph Core library; - Networking core; - IPv6 networking; - L2TP protocol; - MAC80211 subsystem; - Multipath TCP; - NET/ROM layer; - RxRPC session sockets; - SCTP protocol; - SMC sockets; - VMware vSockets driver; - Wireles
CSIRTS triage
- What
- Multiple security flaws across numerous kernel subsystems including architecture, drivers, and network protocols.
- Who is affected
- Systems running affected Linux kernel versions are potentially vulnerable depending on subsystem exposure.
- Urgency
- Severity and urgency depend on specific CVE; kernel patch should be applied as part of regular maintenance cycle.
- Action
- Apply kernel security updates provided by distribution maintainer.

Exploitation outlook
EPSS (FIRST.org) estimates each CVE’s probability of exploitation in the next 30 days — here is the CSIRTS.com read on those numbers.
- Low exploitation riskCVE-2025-711580.15% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 5% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2025-711600.17% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 6% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2025-711610.35% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 28% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2025-711620.19% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 9% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2025-711630.19% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 9% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2025-711800.15% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 5% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2025-711820.16% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 5% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2025-711830.36% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 29% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2025-711840.12% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 2% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2025-711850.19% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 9% of all EPSS-scored CVEs.
