CVE ID : CVE-2022-48771
Published : June 20, 2024, 12:15 p.m. | 1 hour, 4 minutes ago
Description : In the Linux kernel, the following vulnerability has been resolved:
drm/vmwgfx: Fix stale file descriptors on failed usercopy
A failing usercopy of the fence_rep object will lead to a stale entry in
the file descriptor table as put_unused_fd() won’t release it. This
enables userland to refer to a dangling ‘file’ object through that still
valid file descriptor, leading to all kinds of use-after-free
exploitation scenarios.
Fix this by deferring the call to fd_install() until after the usercopy
has succeeded.
Severity: 0.0 | NA
