https://notcve.org/view.php?id=CVE-2009-2849
18 Aug 2009 — The md driver (drivers/md/md.c) in the Linux kernel before 2.6.30.2 might allow local users to cause a denial of service (NULL pointer dereference) via vectors related to "suspend_* sysfs attributes" and the (1) suspend_lo_store or (2) suspend_hi_store functions. NOTE: this is only a vulnerability when sysfs is writable by an attacker.

18 Aug 2009 — The execve function in the Linux kernel, possibly 2.6.30-rc6 and earlier, does not properly clear the current->clear_child_tid pointer, which allows local users to cause a denial of service (memory corruption) or possibly gain privileges via a clone system call with CLONE_CHILD_SETTID or CLONE_CHILD_CLEARTID enabled, which is not properly handled during thread creation and exit.

14 Aug 2009 — The Linux kernel 2.6.0 through 2.6.30.4, and 2.4.4 through 2.4.37.4, does not initialize all function pointers for socket operations in proto_ops structures, which allows local users to trigger a NULL pointer dereference and gain privileges by using mmap to map page zero, placing arbitrary code on this page, and then invoking an unavailable operation, as demonstrated by the sendpage operation (sock_sendpage function) on a PF_PPPOX socket.
