USN-7833-1: Linux kernel vulnerabilities

Published Oct 21, 2025
·
Updated

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; - 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; - ChipIdea USB driver; - USB Type-C support driver; - Framebuffer layer; - TSM Common Guest driver; - File systems infrastructure; - BTRFS file system; - Ceph distributed file system; - Ext4 file system; - F2FS file system; - JFFS2 file system; - JFS file system; - Network file systems library; - Network file system (NFS) client; - Network file system (NFS) server daemon; - SMB network file system; - Memory Management; - Bluetooth subsystem; - Tracing infrastructure; - iouring subsystem; - IPC subsystem; - BPF subsystem; - Perf events; - Kernel exit() syscall; - IRQ subsystem; - Scheduler infrastructure; - Maple Tree data structure library; - Memory management; - Asynchronous Transfer Mode (ATM) subsystem; - Ethernet bridge; - Networking core; - IPv6 networking; - MultiProtocol Label Switching driver; - Netfilter; - NFC subsystem; - Rose network layer; - Network traffic control; - Sun RPC protocol; - TIPC protocol; - TLS protocol; - Unix domain sockets; - VMware vSockets driver; - WCD audio codecs; - USB sound devices; (CVE-2025-38339, CVE-2025-38391, CVE-2025-38262, CVE-2025-38345, CVE-2025-38387, CVE-2025-38373, CVE-2025-38395, CVE-2025-38330, CVE-2025-38425, CVE-2025-38210, CVE-2025-38206, CVE-2025-38219, CVE-2025-38245, CVE-2025-38253, CVE-2025-38401, CVE-2025-38410, CVE-2025-38086, CVE-2025-38340, CVE-2025-38368, CVE-2025-38385, CVE-2025-38384, CVE-2025-38326, CVE-2025-38224, CVE-2025-38338, CVE-2025-38191, CVE-2025-39682, CVE-2025-38343, CVE-2025-38090, CVE-2025-38228, CVE-2025-38182, CVE-2025-38231, CVE-2025-38183, CVE-2025-38184, CVE-2025-38237, CVE-2025-38413, CVE-2025-38356, CVE-2025-38246, CVE-2025-38202, CVE-2025-38248, CVE-2025-38254, CVE-2025-38426, CVE-2025-38429, CVE-2025-38364, CVE-2025-38388, CVE-2025-38435, CVE-2025-38403, CVE-2025-38186, CVE-2025-38199, CVE-2025-38402, CVE-2025-38181, CVE-2025-38264, CVE-2025-38362, CVE-2025-38341, CVE-2025-38422, CVE-2025-38331, CVE-2025-38423, CVE-2025-38233, CVE-2025-38337, CVE-2025-38328, CVE-2025-38196, CVE-2025-38412, CVE-2025-38205, CVE-2025-38242, CVE-2025-38324, CVE-2025-38354, CVE-2025-38347, CVE-2025-38217, CVE-2025-38393, CVE-2025-38392, CVE-2025-38390, CVE-2025-38321, CVE-2025-38541, CVE-2025-38363, CVE-2025-38203, CVE-2025-38250, CVE-2025-38418, CVE-2025-38336, CVE-2025-38333, CVE-2025-38194, CVE-2025-38372, CVE-2025-38348, CVE-2025-38370, CVE-2025-38411, CVE-2025-38188, CVE-2025-38365, CVE-2025-38241, CVE-2025-38201, CVE-2025-38259, CVE-2025-38355, CVE-2025-38227, CVE-2025-38225, CVE-2025-38405, CVE-2025-38329, CVE-2025-38232, CVE-2025-38344, CVE-2025-38238, CVE-2025-38239, CVE-2025-38260, CVE-2025-38257, CVE-2025-38399, CVE-2025-38419, CVE-2025-38430, CVE-2025-38251, CVE-2025-38332, CVE-2025-38220, CVE-2025-38417, CVE-2025-38396, CVE-2025-38234, CVE-2025-38434, CVE-2025-38197, CVE-2025-38436, CVE-2025-38408, CVE-2025-38204, CVE-2025-38222, CVE-2025-38361, CVE-2025-38218, CVE-2025-38212, CVE-2025-38198, CVE-2025-38255, CVE-2025-38389, CVE-2025-38085, CVE-2025-38244, CVE-2025-38089, CVE-2025-38428, CVE-2025-38369, CVE-2025-38189, CVE-2025-38084, CVE-2025-38400, CVE-2025-38382, CVE-2025-38223, CVE-2025-38325, CVE-2025-38263, CVE-2025-38249, CVE-2025-38346, CVE-2025-38320, CVE-2025-38409, CVE-2025-38374, CVE-2025-38208, CVE-2025-38256, CVE-2025-38371, CVE-2025-38192, CVE-2025-38406, CVE-2025-38360, CVE-2025-38258, CVE-2025-38226, CVE-2025-38376, CVE-2025-38375, CVE-2025-38200, CVE-2025-38523, CVE-2025-38334, CVE-2025-38236, CVE-2025-38386, CVE-2025-38421, CVE-2025-38087, CVE-2025-38416, CVE-2025-38179, CVE-2025-38420, CVE-2025-38424, CVE-2025-38377, CVE-2025-38359, CVE-2025-38342, CVE-2025-38431, CVE-2025-38407, CVE-2025-38427, CVE-2025-38229, CVE-2025-38353, CVE-2025-38383, CVE-2025-38211, CVE-2025-38322, CVE-2025-38381, CVE-2025-38261)
