media: vimc: skip .s_stream() for stopped entities
Syzbot reported [1] a warning prompted by a check in call_s_stream()
that checks whether .s_stream() operation is warranted for unstarted
or stopped subdevs.
Add a simple fix in vimc_streamer_pipeline_terminate() ensuring that
entities skip a call to .s_stream() unless they have been previously
properly started.

| In the Linux kernel, the following vulnerability has been resolved:
nfsd: don't ignore the return code of svc_proc_register()
Currently, nfsd_proc_stat_init() ignores the return value of
svc_proc_register(). If the procfile creation fails, then the kernel
will WARN when it tries to remove the entry later.
Fix nfsd_proc_stat_init() to return the same type of pointer as
svc_proc_register(), and fix up nfsd_net_init() to check that and fail
the nfsd_net construction if it occurs.
svc_proc_register() can fail if the dentry can't be allocated, or if an
identical dentry already exists. The second case is pretty unlikely in
the nfsd_net construction codepath, so if this happens, return -ENOMEM. |
| In the Linux kernel, the following vulnerability has been resolved:
nfsd: put dl_stid if fail to queue dl_recall
Before calling nfsd4_run_cb to queue dl_recall to the callback_wq, we
increment the reference count of dl_stid.
We expect that after the corresponding work_struct is processed, the
reference count of dl_stid will be decremented through the callback
function nfsd4_cb_recall_release.
However, if the call to nfsd4_run_cb fails, the incremented reference
count of dl_stid will not be decremented correspondingly, leading to the
following nfs4_stid leak:

wifi: ath11k: add srng->lock for ath11k_hal_srng_* in monitor mode
ath11k_hal_srng_* should be used with srng->lock to protect srng data.
For ath11k_dp_rx_mon_dest_process() and ath11k_dp_full_mon_process_rx(),
they use ath11k_hal_srng_* for many times but never call srng->lock.
So when running (full) monitor mode, warning will occur:
RIP: 0010:ath11k_hal_srng_dst_peek+0x18/0x30 [ath11k]
Call Trace:
? ath11k_hal_srng_dst_peek+0x18/0x30 [ath11k]

So add srng->lock for them to avoid such warnings.
Inorder to fetch the srng->lock, should change srng's definition from
'void' to 'struct hal_srng'. And initialize them elsewhere to prevent
one line of code from being too long. This is consistent with other ring
process functions, such as ath11k_dp_process_rx().

Added a read-only check before calling `txBeginAnon` in `extAlloc`

| In the Linux kernel, the following vulnerability has been resolved:
jfs: add check read-only before truncation in jfs_truncate_nolock()
Added a check for "read-only" mode in the `jfs_truncate_nolock`
function to avoid errors related to writing to a read-only
filesystem.
Call stack:
block_write_begin() {
jfs_write_failed() {
jfs_truncate() {
jfs_truncate_nolock() {
txEnd() {
...
log = JFS_SBI(tblk->sb)->log;
// (log == NULL)
If the `isReadOnly(ip)` condition is triggered in
`jfs_truncate_nolock`, the function execution will stop, and no
further data modification will occur. Instead, the `xtTruncate`
function will be called with the "COMMIT_WMAP" flag, preventing
modifications in "read-only" mode. |

PCI/ASPM: Fix link state exit during switch upstream function removal
Before 456d8aa37d0f ("PCI/ASPM: Disable ASPM on MFD function removal to
avoid use-after-free"), we would free the ASPM link only after the last
function on the bus pertaining to the given link was removed.
That was too late. If function 0 is removed before sibling function,
link->downstream would point to free'd memory after.
After above change, we freed the ASPM parent link state upon any function
removal on the bus pertaining to a given link.
That is too early. If the link is to a PCIe switch with MFD on the upstream
port, then removing functions other than 0 first would free a link which
still remains parent_link to the remaining downstream ports.
The resulting GPFs are especially frequent during hot-unplug, because
pciehp removes devices on the link bus in reverse order.
On that switch, function 0 is the virtual P2P bridge to the internal bus.
Free exactly when function 0 is removed -- before the parent link is
obsolete, but after all subordinate links are gone.

| In the Linux kernel, the following vulnerability has been resolved:
usb: xhci: Don't skip on Stopped - Length Invalid
Up until commit d56b0b2ab142 ("usb: xhci: ensure skipped isoc TDs are
returned when isoc ring is stopped") in v6.11, the driver didn't skip
missed isochronous TDs when handling Stoppend and Stopped - Length
Invalid events. Instead, it erroneously cleared the skip flag, which
would cause the ring to get stuck, as future events won't match the
missed TD which is never removed from the queue until it's cancelled.
This buggy logic seems to have been in place substantially unchanged
since the 3.x series over 10 years ago, which probably speaks first
and foremost about relative rarity of this case in normal usage, but
by the spec I see no reason why it shouldn't be possible.
After d56b0b2ab142, TDs are immediately skipped when handling those
Stopped events. This poses a potential problem in case of Stopped -
Length Invalid, which occurs either on completed TDs (likely already
given back) or Link and No-Op TRBs. Such event won't be recognized
as matching any TD (unless it's the rare Link TRB inside a TD) and
will result in skipping all pending TDs, giving them back possibly
before they are done, risking isoc data loss and maybe UAF by HW.
As a compromise, don't skip and don't clear the skip flag on this
kind of event. Then the next event will skip missed TDs. A downside
of not handling Stopped - Length Invalid on a Link inside a TD is
that if the TD is cancelled, its actual length will not be updated
to account for TRBs (silently) completed before the TD was stopped.
I had no luck producing this sequence of completion events so there
is no compelling demonstration of any resulting disaster. It may be
a very rare, obscure condition. The sole motivation for this patch
is that if such unlikely event does occur, I'd rather risk reporting
a cancelled partially done isoc frame as empty than gamble with UAF.
This will be fixed more properly by looking at Stopped event's TRB
pointer when making skipping decisions, but such rework is unlikely
to be backported to v6.12, which will stay around for a few years. |
| Delinea Secret Server before 11.7.000001 allows attackers to bypass authentication via the SOAP API in SecretServer/webservices/SSWebService.asmx. This is related to a hardcoded key, the use of the integer 2 for the Admin user, and removal of the oauthExpirationId attribute. |
| HCL Connections is vulnerable to a broken access control vulnerability that may allow an unauthorized user to update data in certain scenarios. |
| SAP Business Warehouse - Business Planning and
Simulation application does not sufficiently encode user-controlled inputs,
resulting in Stored Cross-Site Scripting (XSS) vulnerability. This
vulnerability allows users to modify website content and on successful
exploitation, an attacker can cause low impact to the confidentiality and
integrity of the application. |
| Due to a Protection Mechanism Failure in SAP
NetWeaver Application Server for ABAP and ABAP Platform, a developer can bypass
the configured malware scanner API because of a programming error. This leads
to a low impact on the application's confidentiality, integrity, and
availability. |
| SAP BusinessObjects Business Intelligence Platform allows a high privilege user to run client desktop applications even if some of the DLLs are not digitally signed or if the signature is broken. The attacker needs to have local access to the vulnerable system to perform DLL related tasks. This could result in a high impact on confidentiality and integrity of the application. |

Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle VM VirtualBox accessible data as well as unauthorized access to critical data or complete access to all Oracle VM VirtualBox accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle VM VirtualBox.

nvmem: core: fix cleanup after dev_set_name()
If dev_set_name() fails, we leak nvmem->wp_gpio as the cleanup does not
put this. While a minimal fix for this would be to add the gpiod_put()
call, we can do better if we split device_register(), and use the
tested nvmem_release() cleanup code by initialising the device early,
and putting the device.
This results in a slightly larger fix, but results in clear code.
Note: this patch depends on "nvmem: core: initialise nvmem->id early"
and "nvmem: core: remove nvmem_config wp_gpio".
[Srini: Fixed subject line and error code handing with wp_gpio while applying.] |
