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.
