Vulnerability from github – Published: 2026-08-10 12:31 – Updated: 2026-08-10 12:31

Details

In the Linux kernel, the following vulnerability has been resolved:

staging: vme_user: fix location monitor leak in tsi148 bridge

tsi148_probe() allocates a location monitor resource and links it into tsi148_bridge->lm_resources. The probe error path frees this list, but tsi148_remove() only frees the dma, slave and master resource lists, so the location monitor resource is leaked on device unbind or module unload.

Free the lm_resources list in tsi148_remove() as well, before tsi148_bridge is freed.
