CVE-2026-98243

A vulnerability exists in the Linux kernel 's dma-buf/dma-fence component. A previous patch intended to prevent a NULL pointer dereference by testing the ops pointer instead of the signaled bit inadvertently removed RCU protection for many dma_fence implementations. This loss of protection can le...

CVE-2026-98242 dma-buf: Fix silent overflow for phys vec to sgt

In the Linux kernel, the following vulnerability has been resolved: dma-buf: Fix silent overflow for phys vec to sgt In case MMIO size is bigger than 4G and peer2peer DMA goes through host bridge, we trigger a code path that assigns the total linked IOVA which is greater than 4G to mappedlen...

CVE-2026-98242

A vulnerability in the Linux kernel dma-buf subsystem allows for a silent overflow when the MMIO size exceeds 4G during peer-to-peer DMA through a host bridge. The root cause is that mapped_len was declared as a 32-bit unsigned int, causing a wrap-around when accumulating size_t lengths. This tru...

PT-2026-106571

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 7.2.10-1.1 Description An integer overflow occurs in the dma-buf component when the MMIO size exceeds 4G and peer-to-peer DMA is routed through the host bridge. The system assigns the total linked IOVA to the...

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...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: dma-buf/syncfile: Do not leak fences during merge failures. Each call to addfence performs a dmafenceget operation on the relevant fence. In error-prone scenarios, we did not call dmafenceput, resulting in all those fences bei...
