UnknownEPSS 3.47%

Last modified

CVE-2009-4308 is a vulnerability of currently unknown severity. The ext4_decode_error function in fs/ext4/super.c in the ext4 filesystem in the Linux kernel before 2.6.32 allows user-assisted remote attackers to cause a denial of service (NULL pointer dereference), and possibly have unspecified other impact, via a crafted read-only filesystem that lacks a journal.. EPSS estimates a 3.47% chance of exploitation in the next 30 days.
