CVE-2022-1011
A use-after-free flaw was found in the Linux kernel’s FUSE filesystem in the way a user triggers write().
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.17%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
A use-after-free flaw was found in the Linux kernel’s FUSE filesystem in the way a user triggers write(). This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in privilege escalation.
