[/INST] 'cwe': ['CWE-284'], 'message': 'nfsd: check permissions when setting ACLs
Use set_posix_acl, which includes proper permission checks, instead of
calling ->set_acl directly. Without this anyone may be able to grant
themselves permissions to a file by setting the ACL.
Lock the inode to make the new checks atomic with respect to set_acl.
(Also, nfsd was the only caller of set_acl not locking the inode, so I
suspect this may fix other races.)
This also simplifies the code, and ensures our ACLs are checked by
posix_acl_valid.
The permission checks and the inode locking were lost with commit
4ac7249e, which changed nfsd to use the set_acl inode operation directly
instead of going through xattr handlers.

[/INST] 'cwe': ['CWE-362'], 'message': 'audit: fix a double fetch in audit_log_single_execve_arg()
There is a double fetch problem in audit_log_single_execve_arg()
where we first check the execve(2) argumnets for any "bad" characters
which would require hex encoding and then re-fetch the arguments for
logging in the audit record[1]. Of course this leaves a window of
opportunity for an unsavory application to munge with the data.
This patch reworks things by only fetching the argument data once[2]
into a buffer where it is scanned and logged into the audit
records(s). In addition to fixing the double fetch, this patch
improves on the original code in a few other ways: better handling
of large arguments which require encoding, stricter record length
checking, and some performance improvements (completely unverified,
but we got rid of some strlen() calls, that's got to be a good
thing).
As part of the development of this patch, I've also created a basic
regression test for the audit-testsuite, the test can be tracked on
GitHub at the following link:
* https://github.com/linux-audit/audit-testsuite/issues/25
[1] If you pay careful attention, there is actually a triple fetch
problem due to a strnlen_user() call at the top of the function.
[2] This is a tiny white lie, we do make a call to strnlen_user()
prior to fetching the argument data. I don't like it, but due to the
way the audit record is structured we really have no choice unless we
copy the entire argument at once (which would require a rather
wasteful allocation). The good news is that with this patch the
kernel no longer relies on this strnlen_user() value for anything
beyond recording it in the log, we also update it with a trustworthy
value whenever possible.

This patch increases the default limit from 100 to 1000, and adds
some randomization so that the attacker can no longer hijack
sessions without spending a considerable amount of probes.
Based on initial analysis and patch from Linus.
Note that we also have per socket rate limiting, so it is tempting
to remove the host limit in the future.

Unlink and rename in overlayfs checked the upper dentry for staleness by
verifying upper->d_parent against upperdir. However the dentry can go
stale also by being unhashed, for example.
Expand the verification to actually look up the name again (under parent
lock) and check if it matches the upper dentry. This matches what the VFS
does before passing the dentry to filesytem's unlink/rename methods, which
excludes any inconsistency caused by overlayfs.

[/INST] 'cwe': ['CWE-284'], 'message': 'vfs: rename: check backing inode being equal
If a file is renamed to a hardlink of itself POSIX specifies that rename(2)
should do nothing and return success.
This condition is checked in vfs_rename(). However it won't detect hard
links on overlayfs where these are given separate inodes on the overlayfs
layer.
Overlayfs itself detects this condition and returns success without doing
anything, but then vfs_rename() will proceed as if this was a successful
rename (detach_mounts(), d_move()).
The correct thing to do is to detect this condition before even calling
into overlayfs. This patch does this by calling vfs_select_inode() to get
the underlying inodes.

Fix a memory leak on probe error of the airspy usb device driver.
The problem is triggered when more than 64 usb devices register with
v4l2 of type VFL_TYPE_SDR or VFL_TYPE_SUBDEV.
The memory leak is caused by the probe function of the airspy driver
mishandeling errors and not freeing the corresponding control structures
when an error occours registering the device to v4l2 core.
A badusb device can emulate 64 of these devices, and then through
continual emulated connect/disconnect of the 65th device, cause the
kernel to run out of RAM and crash the kernel, thus causing a local DOS
vulnerability.

copy_process(pid => &init_struct_pid) doesn't do attach_pid/etc.
It shouldn't, but this means that the idle threads run with the wrong
pids copied from the caller's task_struct. In x86 case the caller is
either kernel_init() thread or keventd.
In particular, this means that after the series of cpu_up/cpu_down an
idle thread (which never exits) can run with .pid pointing to nowhere.
Change fork_idle() to initialize idle->pids[] correctly. We only set
.pid = &init_struct_pid but do not add .node to list, INIT_TASK() does
the same for the boot-cpu idle thread (swapper).

[/INST] 'cwe': ['CWE-119'], 'message': 'Changed the way MAKERNOTE is handled in case we do not have a matching signature (Remi).
Before this patch, exif_process_IFD_in_MAKERNOTE() would return false, then causing the rest of the EXIF parsing to be interrupted. This is a regression from earlier which was most likely a part of a security fix for MAKERNOTE.
The new behavior is to instead of stopping to parse, to continue so we can still fetch data like thumbnail and GPS, thrus allowing yet unsupported formats to parse. If EXIF's debugging mode is enabled, a notice will display in case we do not match against a valid MAKERNOTE signature.
This should temporarily fix bug #72682 (exif_read_data() fails to read all data for some images) until I get around to debug it further.
