An integer overflow in util-linux through 2.37.1 can potentially cause a buffer overflow if an attacker were able to use system resources in a way that leads to a large number in the /proc/sysvipc/sem file. NOTE: this is unexploitable in GNU C Library environments, and possibly in all realistic environments.

util-linux: integer overflow can lead to buffer overflow in get_sem_elements() in sys-utils/ipcutils.c
An integer overflow in util-linux through 2.37.1 can potentially cause a buffer overflow if an attacker were able to use system resources in a way that leads to a large number in the /proc/sysvipc/sem file. NOTE: this is unexploitable in GNU C Library environments, and possibly in all realistic environments.
An integer truncation flaw was found in util-linux that potentially causes a buffer overflow if an attacker can use system resources that lead to a large number in the /proc/sysvipc/sem file. The highest threat from this vulnerability is to system availability.
Statement: This vulnerability is only present in the 32-bit builds of the util-linux package. The standard 64-bit builds (

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025.
