Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A use-after-free issue exists in the DRM subsystem within the Linux kernel. The bridge counter was not reset during DRM device teardown, leading to potential access of deallocated structures on subsequent teardowns, such as after a probe deferral. Repeated probe deferrals and a sufficient number of bridges could also result in corruption of data beyond the bridge array.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
