USN-7344-2: Linux kernel vulnerabilities
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)
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: - PowerPC architecture; - GPIO subsystem; - GPU drivers; - Media drivers; - Network drivers; - SCSI subsystem; - Direct Digital Synthesis drivers; - TTY drivers; - 9P distributed file system; - JFS file system; - NILFS2 file system; - File systems infrastructure; - BPF subsystem; - Netfilter; - Memory management; - Amateur Radio drivers; - B.A.T.M.A.N. meshing protocol; - Bluetooth subsystem; - Ethernet bridge; - Networking core; - IPv4 networking; - IPv6 networking; - Open vSwitch; - Network traffic control; - TIPC protocol; - Wireless networking; (CVE-2024-50171, CVE-2023-52880, CVE-2023-52522, CVE-2024-53104, CVE-2024-41064, CVE-2024-43892, CVE-2024-43900, CVE-2022-48772, CVE-2024-50148, CVE-2024-41063, CVE-2024-44938, CVE-2023-52799, CVE-2023-52818, CVE-2024-50134, CVE-2024-40943, CVE-2024-50117, CVE-2024-26685, CVE-2024-36964, CVE-2024-36952, CVE-2024-53164, CVE-2024-43893, CVE-2024-50229, CVE-2024-42070, CVE-2024-38567, CVE-2024-38558, CVE-2024-40910, CVE-2024-44931, CVE-2024-36886, CVE-2024-35896, CVE-2024-43863, CVE-2024-40911, CVE-2023-52488, CVE-2024-42068, CVE-2024-50233, CVE-2024-49902, CVE-2024-53156, CVE-2024-40981)
