Status: ModifiedMedium (4.6)—
Use-after-free vulnerability in the path_openat function in fs/namei.c in the Linux kernel 3.x and 4.x before 4.0.4 allows local users to cause a denial of service or possibly have unspecified other impact via O_TMPFILE filesystem operations that leverage a duplicate cleanup operation.
CVSS
- Version: 2.0
- Vector: AV:L/AC:L/Au:N/C:P/I:P/A:P
- Base score: 4.6
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 0.44%
- Percentile among all scored CVEs: 36
- Score date: 10/12/2026
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).
