CVE-2010-2693
FreeBSD 7.1 through 8.1-PRERELEASE does not copy the read-only flag when creating a duplicate mbuf buffer reference, which allows local users to cause a denial of service (system file corruption) and gain privileges via the sendfile system call.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.70%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
