CVE-2011-0699
Integer signedness error in the btrfs_ioctl_space_info function in the Linux kernel 2.6.37 allows local users to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via a crafted slot value.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.32%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
