CVE-2026-53112

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

Description A use-after-free issue exists in the rtlwifi PCI component. The irq prepare bcn tasklet is initialized in rtl pci init() and scheduled upon a RTL IMR BCNINT hardware interrupt. Because this tasklet is not terminated in rtl pci deinit(), it may continue to run or remain pending after the ieee80211 hw is deallocated during a probe failure or card detachment. This leads to a use-after-free condition when the rtl pci prepare bcn tasklet() function attempts to access the freed ieee80211 hw memory.

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