Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: idpf: fix read_dev_clk_lock spinlock
 init in idpf_ptp_init() In idpf_ptp_init(), read_dev_clk_lock is initialized after ptp_schedule_worker()
 had already been called (and after idpf_ptp_settime64() could reach the lock). The PTP aux worker fires
 immediately upon scheduling and can call into idpf_ptp_read_src_clk_reg_direct(), which takes
 spin_lock(&ptp->read_dev_clk_lock) on an uninitialized lock, triggering the lockdep "non-static key"
