SUSE CVE-2026-89996

In the Linux kernel, the following vulnerability has been resolved: dma-buf: dma-heap: don't publish fd before copytouser succeeds DMAHEAPIOCTLALLOC allocates a dma-buf and installs an fd into the caller's fd table via dmabuffd - fdinstall before dmaheapioctl copies the result back to userspace. ...

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...

CVE-2026-89996: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: dma-buf: dma-heap: don't publish fd before copytouser succeeds DMAHEAPIOCTLALLOC allocates a dma-buf and installs an fd into the caller's fd table via dmabuffd - fdinstall before dmaheapioctl copies the result back to userspace. ...

Linux Kernel Security Vulnerabilities

The Linux kernel version 5.6 contains a security vulnerability. This vulnerability arises from DMAHEAPIOCTLALLOC, which releases the fd to the caller’s fd table through fdinstall before copytouser is successful. If copytouser fails, it can lead to the leakage of references to the fd and the...
