net: pds_core: Fix possible double free in error handling path

Noroxi assessment

Priority: Monitor (action score 16/100)

  • 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: 0.30% (FIRST EPSS).
  • Physical access to the device is required. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 995f802abff209514ac2ee03b96224237646cec3, ba18deddd6d502da71fd6b6143c53042271b82bd, ffda0e962f270b3ec937660afd15b685263232d3.

Low priority for now. Upgrade to Linux Linux 995f802abff209514ac2ee03b96224237646cec3, ba18deddd6d502da71fd6b6143c53042271b82bd, ffda0e962f270b3ec937660afd15b685263232d3 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: net: pds_core: Fix possible double free in error handling path When auxiliary_device_add() returns error and then calls auxiliary_device_uninit(), Callback function pdsc_auxbus_dev_release calls kfree(padev) to free memory. We shouldn't call kfree(padev) again in the error handling path. Fix this by cleaning up the redundant kfree() and putting the error handling back to where the errors happened.
