Affected: Linux

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

net_sched: sch_sfq: reject invalid perturb period

Gerrard Tai reported that SFQ perturb_period has no range check yet, and this can be used to trigger a race condition fixed in a separate patch.

We want to make sure ctl->perturb_period * HZ will not overflow and is positive.

 https://cve.radiocsirt.org/vuln/usn-7856-1 USN-7856-1 — linux-hwe-6.14 vulnerabilities 2026-10-17T20:38:37.220411+00:00

Affected: Ubuntu:24.04:LTS: linux-hwe-6.14

Oleksii Oleksenko, Cedric Fournet, Jana Hofmann, Boris Köpf, Stavros Volos, and Flavien Solt discovered that some AMD processors may allow an attacker to infer data from previous stores, potentially resulting in the leakage of privileged information. A local attacker could possibly use this to expose sensitive information. (CVE-2024-36350, CVE-2024-36357)

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; - PowerPC architecture; - RISC-V architecture; - S390 architecture; - x86 architecture; - ACPI drivers; - Serial ATA and Parallel ATA drivers; - ATM drivers; - Drivers core; - ATA over ethernet (AOE) driver; - Ublk userspace block driver; - Bus devices; - DMA engine subsystem; - Arm Firmware Framework for ARMv8-A(FFA); - Cirrus firmware drivers; - GPU drivers; - HID subsystem; - Hardware monitoring drivers; - I2C subsystem; - InfiniBand drivers; - Input Device (Miscellaneous) drivers; - Multiple devices driver; - Media drivers; - TI TPS6594 PFSM driver; - MMC subsystem; - MTD block device drivers; - Network drivers; - NVME drivers; - x86 platform drivers; - RapidIO drivers; - Voltage and Current Regulator drivers; - Remote Processor subsystem; - S/390 drivers; - SCSI subsystem; - TCM subsystem; - Trusted Execution Environment drivers; - TTY drivers;…
