kernel: Linux kernel: Local denial of service and memory leak in DAMON sysfs via setup failure

A flaw was found in the Linux kernel's Data Access MONitor DAMON sysfs interface. A local attacker, typically a privileged user, could exploit a cleanup bug during DAMON context setup. If the setup fails after the attrs directory is created, stale sysfs directories are left behind. This can lead ...

SUSE CVE-2026-31445

In the Linux kernel, the following vulnerability has been resolved: mm/damon/core: avoid use of half-online-committed context One major usage of damoncall is online DAMON parameters update. It is done by calling damoncommitctx inside the damoncall callback function. damoncommitctx can fail for tw...

RHEL 9 : kernel (RHSA-2026:10108)

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:10108 advisory. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fixes: kernel: Bluetooth: MGMT: Fix possible...

CVE-2026-31457

A flaw was found in the Linux kernel. A local user can exploit this vulnerability by setting the nrcontexts parameter to zero via the DAMON sysfs interface while DAMON Data Access MONitor is active. This improper input validation leads to a NULL pointer dereference, which can cause a system crash...

CVE-2026-31458

A flaw was found in the Linux kernel. A privileged local user can exploit this by manipulating the nrcontexts parameter in the mm/damon/sysfs interface to zero while the DAMON Data Access MONitor subsystem is active. This leads to a null pointer dereference when certain sysfs commands are...

CVE-2026-31445

A flaw was found in the Linux kernel. When updating DAMON Data Access MONitor parameters, an internal memory allocation failure during the damoncommitctx function could leave the DAMON context in a partially corrupted state. If this corrupted context is subsequently used, it can lead to unexpecte...
