CVE-2023-54268 debugobjects: Don't wake up kswapd from fill_pool()

In the Linux kernel, the following vulnerability has been resolved: debugobjects: Don't wake up kswapd from fillpool syzbot is reporting a lockdep warning in fillpool because the allocation from debugobjects is using GFPATOMIC, which is GFPHIGH | GFPKSWAPDRECLAIM and therefore tries to wake up...

CVE-2023-54268

The CVE-2023-54268 entry concerns a Linux kernel fix for debugobjects: avoid waking kswapd from fill_pool() when GFP_ATOMIC allocations trigger kswapd_wait::lock. The root cause is using GFP_ATOMIC (effectively GFP_HIGH | GFP_KSWAPD_RECLAIM), which can wake up kswapd during fill_pool() as it may ...

kernel: debugobjects: Don't wake up kswapd from fill_pool()

A locking issue was found in the Linux kernel's debugobjects subsystem. The fillpool function uses GFPATOMIC allocation flags, which attempt to wake up kswapd and acquire kswapdwait::lock. Since fillpool may be called with arbitrary locks already held, this can trigger lockdep warnings about...
