—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 0/100)

  • 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: 0.16% (FIRST EPSS).
  • Fixed version: Linux Linux 258310d59a82ea4854bfd9138682bbaac1153b19, 6.16, bfc721eef5c13704efe6864c7da2ad4b0d75f60a.

Low priority for now. Upgrade to Linux Linux 258310d59a82ea4854bfd9138682bbaac1153b19, 6.16, bfc721eef5c13704efe6864c7da2ad4b0d75f60a or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: module: fix lost error code from codetag_load_module() If codetag_load_module() fails, err is not set to reflect the failure and load_module() returns 0 after the module has been torn down. Also, if the module is a livepatch, mod->klp_info allocated by copy_module_elf() leaks on this error path. Free it via a new livepatch_cleanup label.
