What is CVE-2026-68084?
CVE-2026-68084 is a memory corruption vulnerability in Linux, published on 10 Aug 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
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.
