Descriptions
A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause an out-of-bounds write and a denial of service or unspecified other impact is possible by mounting and operating a crafted ext4 filesystem image.
Se ha detectado una vulnerabilidad en el sistema de archivos ext4 del kernel de Linux. Un usuario local puede provocar una escritura fuera de límites y una denegación de servicio (DoS) u otro impacto no especificado montando y operando una imagen del sistema de archivos ext4 manipulado.
The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Issues addressed include buffer overflow, denial of service, information leakage, null pointer, and use-after-free vulnerabilities.
