UnknownEPSS 0.47%

Last modified

CVE-2009-2849 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.47% chance of exploitation in the next 30 days.
