CVE Descriptions

The make_indexed_dir function in fs/ext4/namei.c in the Linux kernel 2.6.27 before 2.6.27.19 and 2.6.28 before 2.6.28.7 does not validate a certain rec_len field, which allows local users to cause a denial of service (OOPS) by attempting to mount a crafted ext4 filesystem.

EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

Exploit information

Exploit Database EDB-ID : 32775

Publication date : 2009-02-15 23h00 +00:00
Author : Sami Liedes
EDB Verified : Yes

source: https://www.securityfocus.com/bid/33618/info The Linux kernel is prone to a local denial-of-service vulnerability because it fails to properly handle malformed filesystem images. Attackers can exploit this issue to cause the kernel to crash, denying service to legitimate users. Note that to exploit this issue, attackers must be able to mount appropriate filesystem types, which may require membership in a privileged group or root access. This issue affects versions prior to Linux kernel 2.6.27.14. https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/32775.gz
