In the Linux kernel, the following vulnerability has been resolved: schedext: Fixed the issue of starving the scxenable function 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 a higher...

In the Linux kernel, the following vulnerability has been resolved: schedext: Fixed unsafe locking in the scxdumpstate function. For kernels built with CONFIGPREEMPTRT=y, the dumplock will be converted to a sleepable spinlock instead of a disable-irq one. This can lead to the following scenarios:...

This workarou...
Linux Distros Unpatched Vulnerability : CVE-2026-43392
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - schedext: Fix starvation of scxenable under fair-class saturation During scxenable, the READY - ENABLED task switching loop changes the calling thread's...
CVE-2026-43326
A flaw was found in the Linux kernel, specifically within the schedext component. This vulnerability can lead to a system-wide deadlock, causing a Denial of Service DoS where the system becomes unresponsive. The issue arises when the kernel's scheduling mechanism enters a busy-wait state in a...
CVE-2026-43482
In the Linux kernel, the following vulnerability has been resolved: schedext: Disable preemption between scxclaimexit and kicking helper work scxclaimexit atomically sets exitkind, which prevents scxerror from triggering further error handling. After claiming exit, the caller must kick the helper...
Linux Distros Unpatched Vulnerability : CVE-2026-43438
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - schedext: Remove redundant cssput in scxcgroupinit The iterator cssforeachdescendantpre walks the cgroup hierarchy under cgrouplock. It does not increment the...
CVE-2026-43438
A flaw was found in the Linux kernel's schedext component. This vulnerability is caused by a redundant cssput call in the scxcgroupinit function, leading to a reference count underflow. This can result in a Use-After-Free UAF vulnerability, potentially allowing a local attacker to cause a denial ...
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...
