Updated

Chenyuan Yang discovered that the CEC driver driver in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2024-23848)

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: - PowerPC architecture; - S390 architecture; - SuperH RISC architecture; - User-Mode Linux (UML); - x86 architecture; - Cryptographic API; - Virtio block driver; - Data acquisition framework and drivers; - Hardware crypto device drivers; - DMA engine subsystem; - EDAC drivers; - ARM SCPI message protocol; - GPIO subsystem; - GPU drivers; - HID subsystem; - Microsoft Hyper-V drivers; - I3C subsystem; - IIO ADC drivers; - IIO subsystem; - InfiniBand drivers; - LED subsystem; - Multiple devices driver; - Media drivers; - Multifunction device drivers; - MMC subsystem; - MTD block device drivers; - Network drivers; - Mellanox network drivers; - NVME drivers; - PCI subsystem; - Pin controllers subsystem; - x86 platform drivers; - Real Time Clock drivers; - SCSI subsystem; - SuperH / SH-Mobile drivers; - QCOM SoC drivers; - SPI subsystem; - USB Gadget drivers; - USB Serial drivers; - USB Type-C Port Controller Manager driver; - VFIO drivers; - Framebuffer layer; - Xen hypervisor drivers; - BTRFS file system; - Ext4 file system; - F2FS file system; - GFS2 file system; - File systems infrastructure; - JFFS2 file system; - JFS file system; - Network file system (NFS) client; - Network file system (NFS) server daemon; - NILFS2 file system; - Overlay file system; - Proc file system; - Diskquota system; - SMB network file system; - UBI file system; - Timer subsystem; - VLANs driver; - LAPB network protocol; - Kernel init infrastructure; - BPF subsystem; - Kernel CPU control infrastructure; - Tracing infrastructure; - Memory management; - 9P file system network protocol; - Bluetooth subsystem; - CAN network layer; - Networking core; - DCCP (Datagram Congestion Control Protocol); - IEEE802154.4 network protocol; - IPv4 networking; - IPv6 networking; - IEEE 802.15.4 subsystem; - Netfilter; - Netlink; - NET/ROM layer; - Packet sockets; - Network traffic control; - SCTP protocol; - Sun RPC protocol; - TIPC protocol; - eXpress Data Path; - SELinux security module; - USB sound devices; (CVE-2024-53172, CVE-2024-56572, CVE-2024-56739, CVE-2024-56643, CVE-2024-53131, CVE-2024-57904, CVE-2024-53145, CVE-2024-57908, CVE-2024-53155, CVE-2024-56691, CVE-2024-57901, CVE-2024-56595, CVE-2024-55916, CVE-2024-50051, CVE-2024-49936, CVE-2024-57900, CVE-2024-53239, CVE-2024-53142, CVE-2024-57889, CVE-2024-53217, CVE-2024-56619, CVE-2025-21653, CVE-2024-53140, CVE-2024-53130, CVE-2024-43098, CVE-2024-56746, CVE-2024-56650, CVE-2024-56723, CVE-2024-56558, CVE-2024-57884, CVE-2024-56601, CVE-2024-56581, CVE-2024-57906, CVE-2024-57948, CVE-2024-49996, CVE-2024-56598, CVE-2025-21638, CVE-2024-49925, CVE-2024-56767, CVE-2024-53127, CVE-2024-53181, CVE-2024-53194, CVE-2024-57902, CVE-2024-56630, CVE-2024-56567, CVE-2024-56602, CVE-2024-56562, CVE-2024-56596, CVE-2024-56570, CVE-2024-56670, CVE-2024-53135, CVE-2024-56629, CVE-2024-56769, CVE-2024-56637, CVE-2024-56681, CVE-2024-57910, CVE-2024-57892, CVE-2024-56574, CVE-2024-53121, CVE-2024-56532, CVE-2025-21689, CVE-2024-53156, CVE-2024-57912, CVE-2024-56597, CVE-2025-21640, CVE-2024-53690, CVE-2024-56548, CVE-2024-56633, CVE-2024-43900, CVE-2024-56631, CVE-2021-47219, CVE-2024-56659, CVE-2024-53158, CVE-2025-21639, CVE-2024-53136, CVE-2024-56615, CVE-2024-56586, CVE-2024-57946, CVE-2024-57911, CVE-2025-21699, CVE-2025-21664, CVE-2024-53174, CVE-2024-53184, CVE-2024-53138, CVE-2024-53680, CVE-2024-56593, CVE-2024-56644, CVE-2024-56720, CVE-2024-53197, CVE-2024-57802, CVE-2024-53157, CVE-2024-56756, CVE-2024-53171, CVE-2024-57931, CVE-2024-56600, CVE-2024-53112, CVE-2024-56770, CVE-2024-53214, CVE-2024-57849, CVE-2024-57890, CVE-2024-56634, CVE-2024-44938, CVE-2024-53183, CVE-2025-21697, CVE-2024-57929, CVE-2024-53165, CVE-2024-53161, CVE-2024-53150, CVE-2024-56606, CVE-2024-56748, CVE-2024-48881, CVE-2024-56594, CVE-2024-56645, CVE-2024-56781, CVE-2024-56531, CVE-2024-56605, CVE-2024-56779, CVE-2025-21678, CVE-2024-53227, CVE-2024-56688, CVE-2024-56576, CVE-2024-56587, CVE-2024-53124, CVE-2024-49884, CVE-2024-57850, CVE-2024-56569, CVE-2024-53148, CVE-2025-21694, CVE-2024-56700, CVE-2024-53173, CVE-2024-53198, CVE-2024-52332, CVE-2024-47707, CVE-2024-56539, CVE-2024-56704, CVE-2024-56747, CVE-2025-21687, CVE-2024-56690, CVE-2022-49034, CVE-2024-57938, CVE-2024-57951, CVE-2024-38588, CVE-2024-56603, CVE-2024-57807, CVE-2024-56780, CVE-2024-57922, CVE-2024-56642, CVE-2024-57913, CVE-2024-53146, CVE-2024-56614, CVE-2024-56694, CVE-2024-56724)
