In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Use del_timer_sync in fw reset flow of halting poll
Substitute del_timer() with del_timer_sync() in fw reset polling
deactivation flow, in order to prevent a race condition which occurs
when del_timer() is called and timer is deactivated while another
process is handling the timer interrupt. A situation that led to
the following call trace:
RIP: 0010:run_timer_softirq+0x137/0x420
<IRQ>
recalibrate_cpu_khz+0x10/0x10
ktime_get+0x3e/0xa0
? sched_clock_cpu+0xb/0xc0
__do_softirq+0xf5/0x2ea
irq_exit_rcu+0xc1/0xf0
sysvec_apic_timer_interrupt+0x9e/0xc0
asm_sysvec_apic_timer_interrupt+0x12/0x20
</IRQ>
