Race condition in the handle_to_path function in fs/fhandle.c in the Linux kernel through 3.19.1 allows local users to bypass intended size
Noroxi assessment
Priority: Monitor (action score 7/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.36% (FIRST EPSS).
- Fixed version: linux (Debian:12) 3.16.7-ckt7-1; linux (Debian:7) 3.2.65-1+deb7u2; kernel-bigsmp (SUSE:Linux Enterprise Desktop 11 SP3) 3.0.101-0.47.67.2.
Low priority for now. Upgrade to linux (Debian:12) 3.16.7-ckt7-1; linux (Debian:7) 3.2.65-1+deb7u2; kernel-bigsmp (SUSE:Linux Enterprise Desktop 11 SP3) 3.0.101-0.47.67.2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
Race condition in the handle_to_path function in fs/fhandle.c in the Linux kernel through 3.19.1 allows local users to bypass intended size restrictions and trigger read operations on additional memory locations by changing the handle_bytes value of a file handle during the execution of this function.
