CVE-2026-89996

A flaw was found in the Linux kernel's dma-buf subsystem. A local attacker can exploit a race condition during the DMAHEAPIOCTLALLOC operation. If the copytouser function fails after a file descriptor fd has been installed, the fd is leaked for the lifetime of the process. This continuous leaking...
