The Linux Kernel, the operating system core itself.

Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

io_uring: fix memleak in io_init_wq_offload()

I got memory leak report when doing fuzz test:

When calling io_uring_enter() in parallel, the 'hash_map' will be leaked, add uring_lock to protect 'hash_map'.(CVE-2021-47292)

In the Linux kernel, the following vulnerability has been resolved:

io_uring: ensure task_work gets run as part of cancelations

If we successfully cancel a work item but that work item needs to be processed through task_work, then we can be sleeping uninterruptibly in io_uring_cancel_generic() and never process it. Hence we don't make forward progress and we end up with an uninterruptible sleep warning.

While in there, correct a comment that should be IFF, not IIF.(CVE-2021-47504)

In the Linux kernel, the following vulnerability has been resolved:

ethtool: ioctl: fix potential NULL deref in ethtool_set_coalesce()

ethtool_set_coalesce() now uses both the .get_coalesce() and .set_coalesce() callbacks. But the check for their availability is buggy, so changing the coalesce settings on a device where the driver provides only one of the callbacks results in a NULL pointer dereference instead of an -EOPNOTSUPP.

Fix the condition so that the availability of both callbacks is ensured. This also matches the netlink code.

Note that reproducing this requires some effort - it only affects the legacy ioctl path, and needs a specific combination of driver options:

• have .get_coalesce() and .coalesce_supported but no .set_coalesce(), or
• have .set_coalesce() but no .get_coalesce(). Here eg. ethtool doesn't cause the crash as it first attempts to call ethtool_get_coalesce() and bails out on error.(CVE-2021-47556)

In the Linux kernel, the following vulnerability has been resolved:

drm/gma500: Fix BUG: sleeping function called from invalid context errors

gma_crtc_page_flip() was holding the event_lock spinlock while calling crtc_funcs->mode_set_base() which takes ww_mutex.

The only reason to hold event_lock is to clear gma_crtc->page_flip_event on mode_set_base() errors.

Instead unlock it after setting gma_crtc->page_flip_event and on errors re-take…
