Summary
An issue was discovered in the Linux kernel through 4.17.3. An Integer Overflow in kernel/time/posix-timers.c in the POSIX timer code is caused by the way the overrun accounting works. Depending on interval and expiry time values, the overrun can be larger than INT_MAX, but the accounting is int based. This basically makes the accounting values, which are visible to user space via timer_getoverrun(2) and siginfo::si_overrun, random. For example, a local user can cause a denial of service (signed integer overflow) via crafted mmap, futex, timer_create, and timer_settime system calls.

"value": "An issue was discovered in the Linux kernel through 4.17.3. An Integer Overflow in kernel/time/posix-timers.c in the POSIX timer code is caused by the way the overrun accounting works. Depending on interval and expiry time values, the overrun can be larger than INT_MAX, but the accounting is int based. This basically makes the accounting values, which are visible to user space via timer_getoverrun(2) and siginfo::si_overrun, random. For example, a local user can cause a denial of service (signed integer overflow) via crafted mmap, futex, timer_create, and timer_settime system calls."

Un desbordamiento de enteros en kernel/time/posix-timers.c en el c\u00f3digo temporizador POSIX es causado por la forma en que funciona la contabilidad de desbordamiento. Dependiendo de los valores del intervalo y del tiempo de expiraci\u00f3n, el desbordamiento puede ser mayor que INT_MAX, pero la contabilidad est\u00e1 basada en int. Esto b\u00e1sicamente hace que los valores contables, que son visibles para el espacio de usuario a trav\u00e9s de timer_getoverrun(2) y siginfo::si_overrun, sean aleatorios. Por ejemplo, un usuario local puede causar una denegaci\u00f3n de servicio (desbordamiento de enteros firmados) a trav\u00e9s de llamadas al sistema mmap, futex, timer_create y timer_settime manipuladas."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
