HighCVSS 7.5 · v3.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 32/100)

  • 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: 5.5% (FIRST EPSS); higher than 92.9% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: linux (Debian:12) 4.6.2-1; kernel-default (SUSE:Linux Enterprise Desktop 12 SP1) 3.12.62-60.62.1; kernel-source (SUSE:Linux Enterprise Desktop 12 SP1) 3.12.62-60.62.1.

Low priority for now. Upgrade to linux (Debian:12) 4.6.2-1; kernel-default (SUSE:Linux Enterprise Desktop 12 SP1) 3.12.62-60.62.1; kernel-source (SUSE:Linux Enterprise Desktop 12 SP1) 3.12.62-60.62.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The rds_inc_info_copy function in net/rds/recv.c in the Linux kernel through 4.6.3 does not initialize a certain structure member, which allows remote attackers to obtain sensitive information from kernel stack memory by reading an RDS message.

Root cause

The extension requests broader permissions than its function needs and sends the data it collects out for purposes beyond its stated function.

A representative example of this vulnerability class. Not the vendor's source code; it shows the faulty pattern and its fix.
