1DescriptionCVE.org
Race condition in fs/timerfd.c in the Linux kernel before 4.10.15 allows local users to gain privileges or cause a denial of service (list corruption or use-after-free) via simultaneous file-descriptor operations that leverage improper might_cancel queueing.
AnalysisAI
Race condition in fs/timerfd.c in the Linux kernel before 4.10.15 allows local users to gain privileges or cause a denial of service (list corruption or use-after-free) via simultaneous. Rated high severity (CVSS 7.0), this vulnerability is no authentication required. Public exploit code available and EPSS exploitation probability 25.7%.
Technical ContextAI
This vulnerability is classified as Use After Free (CWE-416), which allows attackers to access freed memory to execute arbitrary code or crash the application. Race condition in fs/timerfd.c in the Linux kernel before 4.10.15 allows local users to gain privileges or cause a denial of service (list corruption or use-after-free) via simultaneous file-descriptor operations that leverage improper might_cancel queueing. Affected products include: Linux Linux Kernel, Redhat Enterprise Linux, Redhat Enterprise Linux Aus, Redhat Enterprise Linux Server Eus, Redhat Enterprise Linux Server For Power Little Endian Update Services For Sap Solutions. Version information: before 4.10.15.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Use smart pointers or garbage-collected languages. Set pointers to NULL after freeing. Enable memory sanitizers.
