CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
drm/msm: Do not validate SSPP when it is not ready
Current code will validate current plane and previous plane to
confirm they can share a SSPP with multi-rect mode. The SSPP
is already allocated for previous plane, while current plane
is not associated with any SSPP yet. Null pointer is referenced
when validating the SSPP of current plane. Skip SSPP validation
for current plane.

The bpf_fifo_dequeue prog returns a skb which is a pointer. The pointer
is treated as a 32bit value and sign extend to 64bit in epilogue. This
behavior is right for most bpf prog types but wrong for struct ops which
requires RISC-V ABI.
So let's sign extend struct ops return values according to the function
model and RISC-V ABI([0]).

When hfsplus_uni2asc is called from hfsplus_listxattr,
it actually passes in a struct hfsplus_attr_unistr*.
The size of the corresponding structure is different from that of hfsplus_unistr,
so the previous fix (94458781aee6) is insufficient.
The pointer on the unicode buffer is still going beyond the allocated memory.
This patch introduces two warpper functions hfsplus_uni2asc_xattr_str and
hfsplus_uni2asc_str to process two unicode buffers,
struct hfsplus_attr_unistr* and struct hfsplus_unistr* respectively.
When ustrlen value is bigger than the allocated memory size,
the ustrlen value is limited to an safe size. |
| In the Linux kernel, the following vulnerability has been resolved:
iommu/vt-d: Disallow dirty tracking if incoherent page walk
Dirty page tracking relies on the IOMMU atomically updating the dirty bit
in the paging-structure entry. For this operation to succeed, the paging-
structure memory must be coherent between the IOMMU and the CPU. In
another word, if the iommu page walk is incoherent, dirty page tracking
doesn't work.
The Intel VT-d specification, Section 3.10 "Snoop Behavior" states:
"Remapping hardware encountering the need to atomically update A/EA/D bits
in a paging-structure entry that is not snooped will result in a non-
recoverable fault."
To prevent an IOMMU from being incorrectly configured for dirty page
tracking when it is operating in an incoherent mode, mark SSADS as
supported only when both ecap_slads and ecap_smpwc are supported. |
| In the Linux kernel, the following vulnerability has been resolved:
coresight: trbe: Return NULL pointer for allocation failures
When the TRBE driver fails to allocate a buffer, it currently returns
the error code "-ENOMEM". However, the caller etm_setup_aux() only
checks for a NULL pointer, so it misses the error. As a result, the
driver continues and eventually causes a kernel panic.
Fix this by returning a NULL pointer from arm_trbe_alloc_buffer() on
allocation failures. This allows that the callers can properly handle
the failure. |
| In the Linux kernel, the following vulnerability has been resolved:
RISC-V: KVM: Write hgatp register with valid mode bits
According to the RISC-V Privileged Architecture Spec, when MODE=Bare
is selected,software must write zero to the remaining fields of hgatp.
We have detected the valid mode supported by the HW before, So using a
valid mode to detect how many vmid bits are supported. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/msm: Fix obj leak in VM_BIND error path
If we fail a handle-lookup part way thru, we need to drop the already

| The Auto Featured Image (Auto Post Thumbnail) plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 4.1.7 via the upload_to_library function. This makes it possible for authenticated attackers, with Author-level access and above, to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services. On Cloud instances, this issue allows for metadata retrieval. |

So, in f2fs_merge_page_bio(), let's avoid using fio->encrypted_page after
commit page into internal ipu cache. |

vhost: vringh: Fix copy_to_iter return value check
The return value of copy_to_iter can't be negative, check whether the
copied length is equal to the requested length instead of checking for

| In the Linux kernel, the following vulnerability has been resolved:
nbd: restrict sockets to TCP and UDP
Recently, syzbot started to abuse NBD with all kinds of sockets.
Commit cf1b2326b734 ("nbd: verify socket is supported during setup")
made sure the socket supported a shutdown() method.

| Constellation is the first Confidential Kubernetes. The Constellation CVM image uses LUKS2-encrypted volumes for persistent storage. When opening an encrypted storage device, the CVM uses the libcryptsetup function crypt_activate_by_passhrase. If the VM is successful in opening the partition with the disk encryption key, it treats the volume as confidential. However, due to the unsafe handling of null keyslot algorithms in the cryptsetup 2.8.1, it is possible that the opened volume is not encrypted at all. Cryptsetup prior to version 2.8.1 does not report an error when processing LUKS2-formatted disks that use the cipher_null-ecb algorithm in the keyslot encryption field. This vulnerability is fixed in 2.24.0. |
| Pi-hole Admin Interface is a web interface for managing Pi-hole, a network-level advertisement and internet tracker blocking application. Pi-hole Admin Interface before 6.3 is vulnerable to Carriage Return Line Feed (CRLF) injection. When a request is made to a file ending with the .lp extension, the application performs a redirect without properly sanitizing the input. An attacker can inject carriage return and line feed characters (%0d%0a) to manipulate both the headers and the content of the HTTP response. This enables the injection of arbitrary HTTP response headers, potentially leading to session fixation, cache poisoning, and the weakening or bypassing of browser-based security mechanisms such as Content Security Policy or X-XSS-Protection. This vulnerability is fixed in 6.3. |
| ImageMagick is a software suite to create, edit, compose, or convert bitmap images. ImageMagick versions prior to 7.1.2-8 are vulnerable to denial-of-service due to unsigned integer underflow and division-by-zero in the CLAHEImage function. When tile width or height is zero, unsigned underflow occurs in pointer arithmetic, leading to out-of-bounds memory access, and division-by-zero causes immediate crashes. This issue has been patched in version 7.1.2-8. |
| PILOS (Platform for Interactive Live-Online Seminars) is a frontend for BigBlueButton. Prior to 4.8.0, users with a local account can change their password while logged in. When doing so, all other active sessions are terminated, except for the currently active one. However, the current session’s token remains valid and is not refreshed. If an attacker has previously obtained this session token through another vulnerability, changing the password will not invalidate their access. As a result, the attacker can continue to act as the user even after the password has been changed. This vulnerability is fixed in 4.8.0. |
| An out-of-bounds write vulnerability exists in the XML parser functionality of GCC Productions Inc. Fade In 4.2.0. A specially crafted .fadein file can lead to an out-of-bounds write. An attacker can provide a malicious file to trigger this vulnerability. |
| IBM DB2 High Performance Unload 6.1.0.3, 5.1.0.1, 6.1.0.2, 6.5, 6.5.0.0 IF1, 6.1.0.1, 6.1, and 5.1 could allow an authenticated user to cause the program to crash due an out of bounds write. |
| A vulnerability was identified in code-projects Courier Management System 1.0. This impacts an unknown function of the file /courier/edit-courier.php. The manipulation of the argument OfficeName leads to sql injection. The attack is possible to be carried out remotely. The exploit is publicly available and might be used. |
| IBM Concert Software
1.0.0 through 2.0.0 could allow a user to modify system logs due to improper neutralization of log input. |
