CVE-2010-0307

Status: ModifiedMedium (4.7)—💥 Exploit
The load_elf_binary function in fs/binfmt_elf.c in the Linux kernel before 2.6.32.8 on the x86_64 platform does not ensure that the ELF interpreter is available before a call to the SET_PERSONALITY macro, which allows local users to cause a denial of service (system crash) via a 32-bit application that attempts to execute a 64-bit application and then triggers a segmentation fault, as demonstrated by amd64_killer, related to the flush_old_exec function.
CVSS

Version: 2.0
Vector: AV:L/AC:M/Au:N/C:N/I:N/A:C
Base score: 4.7
Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.83%
Percentile among all scored CVEs: 56
Score date: 10/14/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
