CVE-2006-6304
The do_coredump function in fs/exec.c in the Linux kernel 2.6.19 sets the flag variable to O_EXCL but does not use it, which allows context-dependent attackers to modify arbitrary files via a rewrite attack during a core dump.

Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.55%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
