Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: schedext: The issue of starving the scxenable function under fair-class saturation has been fixed. During scxenable, the READY - ENABLED task switching loop changes the calling thread’s schedclass from fair to ext. Since fair has...

SUSE CVE-2026-43392

In the Linux kernel, the following vulnerability has been resolved: schedext: Fix starvation of scxenable under fair-class saturation During scxenable, the READY - ENABLED task switching loop changes the calling thread's schedclass from fair to ext. Since fair has higher priority than ext,...

CVE-2026-43392

A flaw was found in the schedext component of the Linux kernel. This vulnerability allows a local attacker to cause a system hang by exploiting an issue in the scxenable function. The function's task switching loop can lead to indefinite starvation of the enable thread when higher-priority...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the sched ext component where the scx enable function can suffer from starvation during the READY to ENABLED task switching loop. This occurs because the calling...

Linux kernel 安全漏洞

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which arises from the possibility that scxenable may be infinitely starved during fair class saturation, leading to syst...

The vulnerability of the scx_enable() function in the kernel/sched/ext.c module of the Linux operating system allows a hacker to trigger a service failure.

The vulnerability of the scxenable function in the kernel/sched/ext.c module of the Linux operating system is related to improper error handling. Exploiting this vulnerability can allow a remote attacker to cause a service failure...

CVE-2025-40260

CVE-2025-40260 relates to a Linux kernel sched_ext issue where scx_enable() could crash if helper kthread creation failed during sched_ext selftests. The fix ensures that kthread creation failure propagates an error via PTR_ERR() in scx_alloc_and_add_sched(), allowing scx_enable() to follow the e...
