| In the Linux kernel, the following vulnerability has been resolved:
Revert "drm/msm: Add missing check and destroy for alloc_ordered_workqueue"
This reverts commit 643b7d0869cc7f1f7a5ac7ca6bd25d88f54e31d0.
A recent patch that tried to fix up the msm_drm_init() paths with
respect to the workqueue but only ended up making things worse:
First, the newly added calls to msm_drm_uninit() on early errors would
trigger NULL-pointer dereferences, for example, as the kms pointer would
not have been initialised. (Note that these paths were also modified by
a second broken error handling patch which in effect cancelled out this
part when merged.)
Second, the newly added allocation sanity check would still leak the
previously allocated drm device.
Instead of trying to salvage what was badly broken (and clearly not
tested), let's revert the bad commit so that clean and backportable
fixes can be added in its place.

The problem was caused by the fact that the driver does not check
whether the endpoints it uses are actually present and have the
appropriate types. This can be fixed by adding a simple check of
the endpoints. |

drm/amdkfd: Fix memory leak in kfd_mem_dmamap_userptr()
If the number of pages from the userptr BO differs from the SG BO then the
allocated memory for the SG table doesn't get freed before returning
-EINVAL, which may lead to a memory leak in some error paths. Fix this by
checking the number of pages before allocating memory for the SG table. |
| In the Linux kernel, the following vulnerability has been resolved:
block: fix blktrace debugfs entries leakage
Commit 99d055b4fd4b ("block: remove per-disk debugfs files in
blk_unregister_queue") moves blk_trace_shutdown() from
blk_release_queue() to blk_unregister_queue(), this is safe if blktrace
is created through sysfs, however, there is a regression in corner
case.
blktrace can still be enabled after del_gendisk() through ioctl if
the disk is opened before del_gendisk(), and if blktrace is not shutdown
through ioctl before closing the disk, debugfs entries will be leaked.
Fix this problem by shutdown blktrace in disk_release(), this is safe
because blk_trace_remove() is reentrant. |

| In the Linux kernel, the following vulnerability has been resolved:
dm: verity-loadpin: Only trust verity targets with enforcement
Verity targets can be configured to ignore corrupted data blocks.
LoadPin must only trust verity targets that are configured to
perform some kind of enforcement when data corruption is detected,
like returning an error, restarting the system or triggering a
panic. |
| In the Linux kernel, the following vulnerability has been resolved:
ext4: fix potential memory leak in ext4_fc_record_modified_inode()
As krealloc may return NULL, in this case 'state->fc_modified_inodes'
may not be freed by krealloc, but 'state->fc_modified_inodes' already
set NULL. Then will lead to 'state->fc_modified_inodes' memory leak. |
| In the Linux kernel, the following vulnerability has been resolved:
net: netsec: fix error handling in netsec_register_mdio()
If phy_device_register() fails, phy_device_free() need be called to
put refcount, so memory of phy device and device name can be freed
in callback function.
If get_phy_device() fails, mdiobus_unregister() need be called,
or it will cause warning in mdiobus_free() and kobject is leaked. |
| In the Linux kernel, the following vulnerability has been resolved:
media: dvb-usb: fix memory leak in dvb_usb_adapter_init()
Syzbot reports a memory leak in "dvb_usb_adapter_init()".
The leak is due to not accounting for and freeing current iteration's
adapter->priv in case of an error. Currently if an error occurs,
it will exit before incrementing "num_adapters_initalized",
which is used as a reference counter to free all adap->priv
in "dvb_usb_adapter_exit()". There are multiple error paths that
can exit from before incrementing the counter. Including the
error handling paths for "dvb_usb_adapter_stream_init()",
"dvb_usb_adapter_dvb_init()" and "dvb_usb_adapter_frontend_init()"
within "dvb_usb_adapter_init()".
This means that in case of an error in any of these functions the
current iteration is not accounted for and the current iteration's
adap->priv is not freed.
Fix this by freeing the current iteration's adap->priv in the
"stream_init_err:" label in the error path. The rest of the
(accounted for) adap->priv objects are freed in dvb_usb_adapter_exit()
as expected using the num_adapters_initalized variable.

wifi: ath11k: fix monitor mode bringup crash
When the interface is brought up in monitor mode, it leads
to NULL pointer dereference crash. This crash happens when
the packet type is extracted for a SKB. This extraction
which is present in the received msdu delivery path,is
not needed for the monitor ring packets since they are
all RAW packets. Hence appending the flags with
"RX_FLAG_ONLY_MONITOR" to skip that extraction.

The source of this warning is in iosys_map_clear() called from
dma_buf_vmap(). It conditionally sets values based on map->is_iomem. The
iosys_map variables are allocated uninitialized on the stack leading to
->is_iomem having all kinds of values and not only 0/1.
Fix this by zeroing the iosys_map variables. |

9p/trans_fd: p9_fd_request: kick rx thread if EPOLLIN
p9_read_work() doesn't set Rworksched and doesn't do schedule_work(m->rq)
if list_empty(&m->req_list).
However, if the pipe is full, we need to read more data and this used to
work prior to commit aaec5a95d59615 ("pipe_read: don't wake up the writer
if the pipe is still full").
p9_read_work() does p9_fd_read() -> ... -> anon_pipe_read() which (before
the commit above) triggered the unnecessary wakeup. This wakeup calls
p9_pollwake() which kicks p9_poll_workfn() -> p9_poll_mux(), p9_poll_mux()
will notice EPOLLIN and schedule_work(&m->rq).
This no longer happens after the optimization above, change p9_fd_request()
to use p9_poll_mux() instead of only checking for EPOLLOUT. |

In elf_kexec_load(), a buffer is allocated via kvmalloc() to store fdt.
While it's not freed back to system when kexec kernel is reloaded or
unloaded. Then memory leak is caused. Fix it by introducing riscv
specific function arch_kimage_file_post_load_cleanup(), and freeing the
buffer there. |

pstore/ram: Add check for kstrdup
Add check for the return value of kstrdup() and return the error
if it fails in order to avoid NULL pointer dereference. |

Revert "Bluetooth: btsdio: fix use after free bug in btsdio_remove due to unfinished work"
This reverts commit 1e9ac114c4428fdb7ff4635b45d4f46017e8916f.
This patch introduces a possible null-ptr-def problem. Revert it. And the
fixed bug by this patch have resolved by commit 73f7b171b7c0 ("Bluetooth:
btsdio: fix use after free bug in btsdio_remove due to race condition"). |
| In the Linux kernel, the following vulnerability has been resolved:
exfat: use kvmalloc_array/kvfree instead of kmalloc_array/kfree
The call stack shown below is a scenario in the Linux 4.19 kernel.
Allocating memory failed where exfat fs use kmalloc_array due to
system memory fragmentation, while the u-disk was inserted without
recognition.
Devices such as u-disk using the exfat file system are pluggable and
may be insert into the system at any time.
However, long-term running systems cannot guarantee the continuity of
physical memory. Therefore, it's necessary to address this issue.

By analyzing the exfat code,we found that continuous physical memory
is not required here,so kvmalloc_array is used can solve this problem. |
