--------------------------------
commit af77c56aa35325daa2bc2bed5c2ebf169be61b86 upstream.
syzbot reports kernel infoleak at vcs_read() [1], for buffer can be read
immediately after resize operation. Initialize buffer using kzalloc().

commit 491762b3250fb06a0c97b5198656ea48359eaeed
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICG97Q
CVE: CVE-2022-49982
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
commit 945a9a8e448b65bec055d37eba58f711b39f66f0 upstream.
The error handling code in pvr2_hdw_create forgets to unregister the
v4l2 device. When pvr2_hdw_create returns back to pvr2_context_create,
it calls pvr2_context_destroy to destroy context, but mp->hdw is NULL,
which leads to that pvr2_hdw_destroy directly returns.
Fix this by adding v4l2_device_unregister to decrease the refcount of
usb interface.

^1da177e4c3f41 fs/bio.c Linus Torvalds 2005-04-16 381 * Description:
3f86a82aeb03e6 fs/bio.c Kent Overstreet 2012-09-06 382 * If @bs is NULL, uses kmalloc() to allocate the bio; else the allocation is
3f86a82aeb03e6 fs/bio.c Kent Overstreet 2012-09-06 383 * backed by the @bs's mempool.
3f86a82aeb03e6 fs/bio.c Kent Overstreet 2012-09-06 384 *
d0164adc89f6bb block/bio.c Mel Gorman 2015-11-06 385 * When @bs is not NULL, if %__GFP_DIRECT_RECLAIM is set then bio_alloc will
d0164adc89f6bb block/bio.c Mel Gorman 2015-11-06 386 * always be able to allocate a bio. This is due to the mempool guarantees.
d0164adc89f6bb block/bio.c Mel Gorman 2015-11-06 387 * To make this work, callers must never allocate more than 1 bio at a time
d0164adc89f6bb block/bio.c Mel Gorman 2015-11-06 388 * from this pool. Callers that need to allocate more than 1 bio must always
d0164adc89f6bb block/bio.c Mel Gorman 2015-11-06 389 * submit the previously allocated bio for IO before attempting to allocate
d0164adc89f6bb block/bio.c Mel Gorman 2015-11-06 390 * a new one. Failure to do so can cause deadlocks under memory pressure.

ed00aabd5eb9fb block/bio.c Christoph Hellwig 2020-07-01 392 * Note that when running under submit_bio_noacct() (i.e. any block
df2cb6daa4cbc3 fs/bio.c Kent Overstreet 2012-09-10 393 * driver), bios are not submitted until after you return - see the code in
ed00aabd5eb9fb block/bio.c Christoph Hellwig 2020-07-01 394 * submit_bio_noacct() that converts recursion into iteration, to prevent

ed00aabd5eb9fb block/bio.c Christoph Hellwig 2020-07-01 398 * submit_bio_noacct() would be susceptible to deadlocks, but we have

[PATCH openEuler-1.0-LTS] spmi: trace: fix stack-out-of-bound access in SPMI tracing functions

commit ac730c72bddc889f5610d51d8a7abf425e08da1a
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICG8JW
CVE: CVE-2022-50094
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
commit 2af28b241eea816e6f7668d1954f15894b45d7e3 upstream.
trace_spmi_write_begin() and trace_spmi_read_end() both call
memcpy() with a length of "len + 1". This leads to one extra
byte being read beyond the end of the specified buffer. Fix
this out-of-bound memory access by using a length of "len"
instead.
Here is a KASAN log showing the issue:

When the prefetch state is not XCALL_CACHE_NONE or XCALL_CACHE_READY for
a long time, such as XCALL_CACHE_CANCEL or XCALL_CACHE_PREFETCH,
the following soft lockup occurs. Fix it by voluntarily yield the CPU
when a timeout occurs in the xcall read while loop.
