| In the Linux kernel, the following vulnerability has been resolved:
i2c: core: Run atomic i2c xfer when !preemptible
Since bae1d3a05a8b, i2c transfers are non-atomic if preemption is
disabled. However, non-atomic i2c transfers require preemption (e.g. in
wait_for_completion() while waiting for the DMA).
panic() calls preempt_disable_notrace() before calling
emergency_restart(). Therefore, if an i2c device is used for the
restart, the xfer should be atomic. This avoids warnings like:

Use !preemptible() instead, which is basically the same check as
pre-v5.2. |

mtd: parsers: qcom: Fix missing free for pparts in cleanup
Mtdpart doesn't free pparts when a cleanup function is declared.
Add missing free for pparts in cleanup function for smem to fix the
leak. |
| In the Linux kernel, the following vulnerability has been resolved:
cxl/region: Do not try to cleanup after cxl_region_setup_targets() fails
Commit 5e42bcbc3fef ("cxl/region: decrement ->nr_targets on error in
cxl_region_attach()") tried to avoid 'eiw' initialization errors when
->nr_targets exceeded 16, by just decrementing ->nr_targets when
cxl_region_setup_targets() failed.
Commit 86987c766276 ("cxl/region: Cleanup target list on attach error")
extended that cleanup to also clear cxled->pos and p->targets[pos]. The
initialization error was incidentally fixed separately by:
Commit 8d4285425714 ("cxl/region: Fix port setup uninitialized variable
warnings") which was merged a few days after 5e42bcbc3fef.
But now the original cleanup when cxl_region_setup_targets() fails
prevents endpoint and switch decoder resources from being reused:
1) the cleanup does not set the decoder's region to NULL, which results
in future dpa_size_store() calls returning -EBUSY
2) the decoder is not properly freed, which results in future commit
errors associated with the upstream switch
Now that the initialization errors were fixed separately, the proper
cleanup for this case is to just return immediately. Then the resources
associated with this target get cleanup up as normal when the failed
region is deleted.
The ->nr_targets decrement in the error case also helped prevent
a p->targets[] array overflow, so add a new check to prevent against
that overflow.
Tested by trying to create an invalid region for a 2 switch * 2 endpoint
topology, and then following up with creating a valid region. |
| In the Linux kernel, the following vulnerability has been resolved:
ceph: fix inode reference leakage in ceph_get_snapdir()
The ceph_get_inode() will search for or insert a new inode into the
hash for the given vino, and return a reference to it. If new is
non-NULL, its reference is consumed.
We should release the reference when in error handing cases. |
| In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: Fix mlx5e_priv_init() cleanup flow
When mlx5e_priv_init() fails, the cleanup flow calls mlx5e_selq_cleanup which
calls mlx5e_selq_apply() that assures that the `priv->state_lock` is held using
lockdep_is_held().
Acquire the state_lock in mlx5e_selq_cleanup().

| Ashlar-Vellum Graphite VC6 File Parsing Uninitialized Variable Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Ashlar-Vellum Graphite. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of VC6 files. The issue results from the lack of proper initialization of memory prior to accessing it. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-25475. |

| Dragonfly is an open source P2P-based file distribution and image acceleration system. Prior to 2.1.0, the processPieceFromSource method does not update the structure’s usedTraffic field, because an uninitialized variable n is used as a guard to the AddTraffic method call, instead of the result.Size variable. A task is processed by a peer. The usedTraffic metadata is not updated during the processing. Rate limiting is incorrectly applied, leading to a denial-of-service condition for the peer. This vulnerability is fixed in 2.1.0. |
| In the Linux kernel, the following vulnerability has been resolved:
r8169: Fix possible ring buffer corruption on fragmented Tx packets.
An issue was found on the RTL8125b when transmitting small fragmented
packets, whereby invalid entries were inserted into the transmit ring
buffer, subsequently leading to calls to dma_unmap_single() with a null
address.
This was caused by rtl8169_start_xmit() not noticing changes to nr_frags
which may occur when small packets are padded (to work around hardware
quirks) in rtl8169_tso_csum_v2().
To fix this, postpone inspecting nr_frags until after any padding has been
applied. |
| In writeToParcel of CursorWindow.cpp, there is a possible out of bounds read due to uninitialized data. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation. |

| Inappropriate implementation in Toolbar in Google Chrome on Android prior to 140.0.7339.80 allowed a remote attacker who convinced a user to engage in specific UI gestures to perform domain spoofing via a crafted HTML page. (Chromium security severity: Medium) |
| Llama.cpp is LLM inference in C/C++. There is a use of uninitialized heap variable vulnerability in gguf_init_from_file, the code will free this uninitialized variable later. In a simple POC, it will directly cause a crash. If the file is carefully constructed, it may be possible to control this uninitialized value and cause arbitrary address free problems. This may further lead to be exploited. Causes llama.cpp to crash (DoS) and may even lead to arbitrary code execution (RCE). This vulnerability has been patched in commit b2740.

| In dng_lossless_decoder::HuffDecode of dng_lossless_jpeg.cpp, there is a possible way to cause a crash due to uninitialized data. This could lead to remote denial of service with no additional execution privileges needed. User interaction is not needed for exploitation. |
| A maliciously crafted STP or SLDPRT file, when parsed in ODXSW_DLL.dll through Autodesk applications, can be used to uninitialized variables. This vulnerability, along with other vulnerabilities, can lead to code execution in the current process. |
| Incomplete cleanup in Intel(R) Power Gadget software for macOS all versions may allow an authenticated user to potentially enable denial of service via local access. |
| DNN (formerly DotNetNuke) is an open-source web content management platform (CMS) in the Microsoft ecosystem. A url could be crafted to the DNN ImageHandler to render text from a querystring parameter. This text would display in the resulting image and a user that trusts the domain might think that the information is legitimate. This vulnerability is fixed in 9.13.4. |
