In the Linux kernel, the following vulnerabilities have been resolved: i2c: acpi: fixed a resource leak in device addition during reconfiguration. The acpii2cfindadapterbyhandle function calls busfinddevice, which takes a reference to the adapter. This reference is never released, resulting in a...

Astra Linux – Vulnerability in Wayland

An internal reference count is maintained on the buffer pool; this count increments every time a new buffer is created from the pool. The reference count is stored as an integer. On LP64 systems, this can lead to an overflow if the client creates a large number of wlshm buffer objects, or if it...
