CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
net: libwx: fix memory leak in wx_setup_rx_resources
When wx_alloc_page_pool() failed in wx_setup_rx_resources(), it doesn't
release DMA buffer. Add dma_free_coherent() in the error path to release
the DMA buffer. |
| In the Linux kernel, the following vulnerability has been resolved:
bus: mhi: ep: Only send -ENOTCONN status if client driver is available
For the STOP and RESET commands, only send the channel disconnect status
-ENOTCONN if client driver is available. Otherwise, it will result in
null pointer dereference. |
| In the Linux kernel, the following vulnerability has been resolved:
net: ethernet: mtk_eth_soc: fix possible NULL pointer dereference in mtk_hwlro_get_fdir_all()
rule_locs is allocated in ethtool_get_rxnfc and the size is determined by
rule_cnt from user space. So rule_cnt needs to be check before using
rule_locs to avoid NULL pointer dereference. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/ttm: Don't leak a resource on eviction error
On eviction errors other than -EMULTIHOP we were leaking a resource.
Fix.
v2:
- Avoid yet another goto (Andi Shyti) |
| In the Linux kernel, the following vulnerability has been resolved:
media: dvb-usb: m920x: Fix a potential memory leak in m920x_i2c_xfer()
'read' is freed when it is known to be NULL, but not when a read error
occurs.
Revert the logic to avoid a small leak, should a m920x_read() call fail. |
| In the Linux kernel, the following vulnerability has been resolved:
btrfs: release path before inode lookup during the ino lookup ioctl
During the ino lookup ioctl we can end up calling btrfs_iget() to get an
inode reference while we are holding on a root's btree. If btrfs_iget()
needs to lookup the inode from the root's btree, because it's not
currently loaded in memory, then it will need to lock another or the
same path in the same root btree. This may result in a deadlock and
trigger the following lockdep splat:

| In the Linux kernel, the following vulnerability has been resolved:
vduse: fix NULL pointer dereference
vduse_vdpa_set_vq_affinity callback can be called
with NULL value as cpu_mask when deleting the vduse
device.
This patch resets virtqueue's IRQ affinity mask value
to set all CPUs instead of dereferencing NULL cpu_mask.

| In the Linux kernel, the following vulnerability has been resolved:
ALSA: ymfpci: Create card with device-managed snd_devm_card_new()
snd_card_ymfpci_remove() was removed in commit c6e6bb5eab74 ("ALSA:
ymfpci: Allocate resources with device-managed APIs"), but the call to
snd_card_new() was not replaced with snd_devm_card_new().
Since there was no longer a call to snd_card_free, unloading the module
would eventually result in Oops:

net: macb: fix a memory corruption in extended buffer descriptor mode
For quite some time we were chasing a bug which looked like a sudden
permanent failure of networking and mmc on some of our devices.
The bug was very sensitive to any software changes and even more to
any kernel debug options.
Finally we got a setup where the problem was reproducible with
CONFIG_DMA_API_DEBUG=y and it revealed the issue with the rx dma:

net/mlx5e: TC, Fix using eswitch mapping in nic mode
Cited patch is using the eswitch object mapping pool while

Fix that by using either nic or eswitch object mapping pool
depending if eswitch is enabled or not.

| In the Linux kernel, the following vulnerability has been resolved:
misc: pci_endpoint_test: Free IRQs before removing the device
In pci_endpoint_test_remove(), freeing the IRQs after removing the device
creates a small race window for IRQs to be received with the test device
memory already released, causing the IRQ handler to access invalid memory,
resulting in an oops.
Free the device IRQs before removing the device to avoid this issue. |
| In the Linux kernel, the following vulnerability has been resolved:
crypto: qat - fix out-of-bounds read
When preparing an AER-CTR request, the driver copies the key provided by
the user into a data structure that is accessible by the firmware.
If the target device is QAT GEN4, the key size is rounded up by 16 since
a rounded up size is expected by the device.
If the key size is rounded up before the copy, the size used for copying
the key might be bigger than the size of the region containing the key,
causing an out-of-bounds read.
Fix by doing the copy first and then update the keylen.
This is to fix the following warning reported by KASAN:
