CVE-2026-46121

The CVE-2026-46121 issue affects the Linux kernel DAMON sysfs interface (mm/damon/sysfs-schemes). A race between reads and writes of memcg_path and path can lead to a use-after-free when a user reads or writes the sysfs files while a buffer is being deallocated. The root cause is that user-direct...

In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx5: Fix memory leak in GETDATADIRECTSYSFSPATH handler The UVERBSHANDLERMLX5IBMETHODGETDATADIRECTSYSFSPATH function allocates memory for the device path using kobjectgetpath. If the length of the device path exceeds the...

CVE-2026-45922

A flaw was found in the Linux kernel, specifically within the RDMA/mlx5 component. When the GETDATADIRECTSYSFSPATH handler processes a device path, it allocates memory. If the device path's length exceeds the designated output buffer, the allocated memory is not properly released. This oversight...
