What, why and how

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.

What

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.

Why

The product calls free() twice on the same memory address.

How

An attacker operating through physical access may attempt exploitation without authentication after a user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
physical access → Double Free → cause the confidentiality, integrity or availability impact described by the vendor
Attack surface
Physical
Privileges required
None: unauthenticated exploitation is possible
User interaction
Required interaction required
Attack complexity
Low: no specialised conditions are recorded
Security boundary
Unchanged: impact remains within the vulnerable component's security authority
Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-415

CWE-415: Double Free. The product calls free() twice on the same memory address.

CVSS vector
?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.
CVSS:3.1/AV:P/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L

Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.

AVPhysicalAttack vector: The attacker needs physical access to the vulnerable system.ACLowAttack complexity: No specialised conditions are required beyond attacker-controlled input.PRNonePrivileges required: The attacker does not need an account or existing privileges.UIRequiredUser interaction: Another user must perform an action for exploitation to succeed.SUnchangedScope: The security impact remains within the vulnerable component's authority.CLowConfidentiality impact: A successful attack can cause a limited loss.ILowIntegrity impact: A successful attack can cause a limited loss.ALowAvailability impact: A successful attack can cause a limited loss.
Post-exploitation / living off the land
No specific living-off-the-land technique is confirmed in the structured sources. Monitor normal administration tools for activity inconsistent with the affected service's baseline.
