| In the Linux kernel, the following vulnerability has been resolved:
fgraph: Do not enable function_graph tracer when setting funcgraph-args
When setting the funcgraph-args option when function graph tracer is net
enabled, it incorrectly enables it. Worse, it unregisters itself when it
was never registered. Then when it gets enabled again, it will register
itself a second time causing a WARNing.

Notice the "tracer: nop" at the top there. The current tracer is the "nop"
tracer, but the content is obviously the function graph tracer.
Enabling function graph tracing will cause it to register again and
trigger a warning in the accounting:

| In the Linux kernel, the following vulnerability has been resolved:
firmware: cs_dsp: Fix OOB memory read access in KUnit test (ctl cache)
KASAN reported out of bounds access - cs_dsp_ctl_cache_init_multiple_offsets().
The code uses mock_coeff_template.length_bytes (4 bytes) for register value
allocations. But later, this length is set to 8 bytes which causes
test code failures.
As fix, just remove the lenght override, keeping the original value 4
for all operations. |

KVM: x86/hyper-v: Skip non-canonical addresses during PV TLB flush
In KVM guests with Hyper-V hypercalls enabled, the hypercalls
HVCALL_FLUSH_VIRTUAL_ADDRESS_LIST and HVCALL_FLUSH_VIRTUAL_ADDRESS_LIST_EX
allow a guest to request invalidation of portions of a virtual TLB.
For this, the hypercall parameter includes a list of GVAs that are supposed
to be invalidated.
However, when non-canonical GVAs are passed, there is currently no
filtering in place and they are eventually passed to checked invocations of
INVVPID on Intel / INVLPGA on AMD. While AMD's INVLPGA silently ignores
non-canonical addresses (effectively a no-op), Intel's INVVPID explicitly
signals VM-Fail and ultimately triggers the WARN_ONCE in invvpid_error():
invvpid failed: ext=0x0 vpid=1 gva=0xaaaaaaaaaaaaa000

Hyper-V documents that invalid GVAs (those that are beyond a partition's
GVA space) are to be ignored. While not completely clear whether this
ruling also applies to non-canonical GVAs, it is likely fine to make that
assumption, and manual testing on Azure confirms "real" Hyper-V interprets
the specification in the same way.
Skip non-canonical GVAs when processing the list of address to avoid
tripping the INVVPID failure. Alternatively, KVM could filter out "bad"
GVAs before inserting into the FIFO, but practically speaking the only
downside of pushing validation to the final processing is that doing so
is suboptimal for the guest, and no well-behaved guest will request TLB
flushes for non-canonical addresses. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/qedr: Fix potential memory leak in __qedr_alloc_mr()
__qedr_alloc_mr() allocates a memory chunk for "mr->info.pbl_table" with
init_mr_info(). When rdma_alloc_tid() and rdma_register_tid() fail, "mr"
is released while "mr->info.pbl_table" is not released, which will lead
to a memory leak.
We should release the "mr->info.pbl_table" with qedr_free_pbl() when error
occurs to fix the memory leak. |

memstick/ms_block: Fix a memory leak
'erased_blocks_bitmap' is never freed. As it is allocated at the same time
as 'used_blocks_bitmap', it is likely that it should be freed also at the
same time.
Add the corresponding bitmap_free() in msb_data_clear(). |

mmc: sdhci-of-esdhc: Fix refcount leak in esdhc_signal_voltage_switch
of_find_matching_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.
of_node_put() checks null pointer. |

posix-cpu-timers: Cleanup CPU timers before freeing them during exec
Commit 55e8c8eb2c7b ("posix-cpu-timers: Store a reference to a pid not a
task") started looking up tasks by PID when deleting a CPU timer.
When a non-leader thread calls execve, it will switch PIDs with the leader
process. Then, as it calls exit_itimers, posix_cpu_timer_del cannot find
the task because the timer still points out to the old PID.
That means that armed timers won't be disarmed, that is, they won't be
removed from the timerqueue_list. exit_itimers will still release their
memory, and when that list is later processed, it leads to a
use-after-free.
Clean up the timers from the de-threaded task before freeing them. This
prevents a reported use-after-free. |

spmi: trace: fix stack-out-of-bound access in SPMI tracing functions
trace_spmi_write_begin() and trace_spmi_read_end() both call

after converting the type of the first argument (@nr, bit number)
of arch_test_bit() from `long` to `unsigned long`[0].
Under certain conditions (for example, when ACPI NUMA is disabled
via command line), pxm_to_node() can return %NUMA_NO_NODE (-1).
It is valid 'magic' number of NUMA node, but not valid bit number
to use in bitops.
node_online() eventually descends to test_bit() without checking
for the input, assuming it's on caller side (which might be good
for perf-critical tasks). There, -1 becomes %ULONG_MAX which leads
to an insane array index when calculating bit position in memory.
For now, add an explicit check for @node being not %NUMA_NO_NODE
before calling test_bit(). The actual logics didn't change here
at all.

While we debug the issue, we found running fstests generic/551 on 5GB
non-zoned null_blk device in the emulated zoned mode also had a
similar hung issue.
Also, we can reproduce the same symptom with an error injected
cow_file_range() setup.
The hang occurs when cow_file_range() fails in the middle of
allocation. cow_file_range() called from do_allocation_zoned() can
split the give region ([start, end]) for allocation depending on
current block group usages. When btrfs can allocate bytes for one part
of the split regions but fails for the other region (e.g. because of
-ENOSPC), we return the error leaving the pages in the succeeded regions
locked. Technically, this occurs only when @unlock == 0. Otherwise, we
unlock the pages in an allocated region after creating an ordered
extent.
Considering the callers of cow_file_range(unlock=0) won't write out
the pages, we can unlock the pages on error exit from
cow_file_range(). So, we can ensure all the pages except @locked_page
are unlocked on error case.
In summary, cow_file_range now behaves like this:
- page_started == 1 (return value)
- All the pages are unlocked. IO is started.
- unlock == 1
- All the pages except @locked_page are unlocked in any case
- unlock == 0
- On success, all the pages are locked for writing out them
- On failure, all the pages except @locked_page are unlocked |
| In the Linux kernel, the following vulnerability has been resolved:
btrfs: replace BTRFS_MAX_EXTENT_SIZE with fs_info->max_extent_size
On zoned filesystem, data write out is limited by max_zone_append_size,
and a large ordered extent is split according the size of a bio. OTOH,
the number of extents to be written is calculated using
BTRFS_MAX_EXTENT_SIZE, and that estimated number is used to reserve the
metadata bytes to update and/or create the metadata items.
The metadata reservation is done at e.g, btrfs_buffered_write() and then
released according to the estimation changes. Thus, if the number of extent
increases massively, the reserved metadata can run out.
The increase of the number of extents easily occurs on zoned filesystem
if BTRFS_MAX_EXTENT_SIZE > max_zone_append_size. And, it causes the
following warning on a small RAM environment with disabling metadata
over-commit (in the following patch).

| Vasion Print (formerly PrinterLogic) Virtual Appliance Host versions prior to 22.0.893 and Application versions prior to 20.0.2140 (macOS/Linux client deployments) are built against OpenSSL 1.0.2h-fips (released May 2016), which has been end-of-life since 2019 and is no longer supported by the OpenSSL project. Continued use of this outdated cryptographic library exposes deployments to known vulnerabilities that are no longer patched, weakening the overall security posture. Affected daemons may emit deprecation warnings and rely on cryptographic components with unresolved security flaws, potentially enabling attackers to exploit weaknesses in TLS/SSL processing or cryptographic operations. This vulnerability has been identified by the vendor as: V-2023-021 — Out-of-Date OpenSSL Library. |
| Vasion Print (formerly PrinterLogic) Virtual Appliance Host versions prior to 1.0.735 and Application versions prior to 20.0.1330 (macOS/Linux client deployments) contain a vulnerability in the local inter-process communication (IPC) mechanism. The software stores IPC request and response files inside /opt/PrinterInstallerClient/tmp with world-readable and world-writable permissions. Any local user can craft malicious request files that are processed by privileged daemons, leading to unauthorized actions being executed in other user sessions. This breaks user session isolation, potentially allowing local attackers to hijack sessions, perform unintended actions in the context of other users, and impact system integrity and availability. This vulnerability has been identified by the vendor as: V-2022-004 — Client Inter-process Security. |
| Vasion Print (formerly PrinterLogic) Virtual Appliance Host versions prior to 1.0.735 and Application prior to 20.0.1330 (macOS/Linux client deployments) contain a vulnerability in the local logging mechanism. Authentication session tokens, including PHPSESSID, XSRF-TOKEN, and laravel_session, are stored in cleartext within world-readable log files. Any local user with access to the machine can extract these session tokens and use them to authenticate remotely to the SaaS environment, bypassing normal login credentials, potentially leading to unauthorized system access and exposure of sensitive information. This vulnerability has been identified by the vendor as: V-2022-008 — Secrets Leaked in Logs. |
