Noroxi assessment

Priority: Monitor (action score 28/100)

  • Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1.8% (FIRST EPSS); higher than 78.5% of all records.
  • Fixed version: kernel-source (openSUSE:Tumbleweed) 4.8.13-1.1.

Low priority for now. Upgrade to kernel-source (openSUSE:Tumbleweed) 4.8.13-1.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The Linux kernel 2.6.33.2 and earlier, when a ReiserFS filesystem exists, does not restrict read or write access to the .reiserfs_priv directory, which allows local users to gain privileges by modifying (1) extended attributes or (2) ACLs, as demonstrated by deleting a file under .reiserfs_priv/xattrs/.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
