CVE-2023-52664: net: atlantic: eliminate double free in error handling logic

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 0.27% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 0edb3ae8bfa31cd544b0c195bdec00e036002b5d, b3cb7a830a24527877b0bc900b9bd74a96aea928, c11a870a73a3bc4cc7df6dd877a45b181795fcbf.

Low priority for now. Upgrade to Linux Linux 0edb3ae8bfa31cd544b0c195bdec00e036002b5d, b3cb7a830a24527877b0bc900b9bd74a96aea928, c11a870a73a3bc4cc7df6dd877a45b181795fcbf or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: net: atlantic: eliminate double free in error handling logic Driver has a logic leak in ring data allocation/free, where aq_ring_free could be called multiple times on same ring, if system is under stress and got memory allocation error. Ring pointer was used as an indicator of failure, but this is not correct since only ring data is allocated/deallocated. Ring itself is an array member. Changing ring allocation functions to return error code directly. This simplifies error handling and eliminates aq_ring_free on higher layer.
