UBUNTU-CVE-2023-53171

In the Linux kernel, the following vulnerability has been resolved: vfio/type1: prevent underflow of lockedvm via exec When a vfio container is preserved across exec, the task does not change, but it gets a new mm with lockedvm=0, and loses the count from existing dma mappings. If the user later...

CVE-2023-53181 dma-buf/dma-resv: Stop leaking on krealloc() failure

In the Linux kernel, the following vulnerability has been resolved: dma-buf/dma-resv: Stop leaking on krealloc failure Currently dmaresvgetfences will leak the previously allocated array if the fence iteration got restarted and the kreallocarray fails. Free the old array by hand, and make sure we...

CVE-2023-53171

CVE-2023-53171 affects the Linux kernel’s vfio/type1 path. The issue occurs when a vfio container is preserved across execs: the task’s mm can change to a new mm with locked_vm=0, causing undercounted DMA mappings and a later unmap to underflow locked_vm, leading to ENOMEM on a subsequent dma map...
