The vulnerability of the vb2_dma_sg_mmap() function in the drivers/media/common/videobuf2/videobuf2-dma-sg.c module of the Linux operating system’s multimedia device driver allows a hacker to cause a service failure.

The vulnerability of the vb2dmasgmmap function in the drivers/media/common/videobuf2/videobuf2-dma-sg.c module of the Linux multimedia device driver lies in the invocation of this function with incorrectly defined arguments. Exploiting this vulnerability could allow an attacker to cause a system...

In the Linux kernel, the following vulnerability has been resolved: media: videobuf2: Set vmaflags in vb2dmasgmmap vb2dmacontig sets VMA flags VMDONTEXPAND and VMDONTDUMP and I do not see a reason why vb2dmasg should behave differently. This avoids hitting WARNON!vma-vmflags & VMDONTEXPAND; in...

CVE-2026-46312

A flaw was found in the videobuf2 subsystem of the Linux kernel. The vb2dmasgmmap function did not correctly set Virtual Memory Area VMA flags, specifically VMDONTEXPAND and VMDONTDUMP. This oversight could lead to a kernel warning and system crash when mapping an imported Direct Memory Access DM...
