CVSS v3.1
5.5
Medium
| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions:
Linux kernel versions prior to 6.15.0-rc6
Description:
The Linux kernel contains a flaw within the ptp subsystem related to recursive locking. Specifically, the
ptp vclock in use() function includes a check for ptp->n vclocks that can lead to a deadlock when acquiring the ptp->n vclocks mux lock, particularly during the unregistration of virtual clocks. The issue arises from a redundant check for ptp->n vclocks within the function. The call trace indicates a potential recursive lock acquisition when attempting to acquire ptp->n vclocks mux while it is already held by another part of the code.Recommendations:
Linux kernel versions prior to 6.15.0-rc6: Remove the logic that checks
ptp->n vclocks in the ptp vclock in use() function.Exploit
