btrfs: don't abort filesystem when attempting to snapshot deleted subvolume
If the source file descriptor to the snapshot ioctl refers to a deleted
subvolume, we get the following abort:

BTRFS: error (device vdc: state A) in create_pending_snapshot:1875: errno=-2 No such entry
BTRFS info (device vdc: state EA): forced readonly
BTRFS warning (device vdc: state EA): Skipping commit of aborted transaction.
BTRFS: error (device vdc: state EA) in cleanup_transaction:2055: errno=-2 No such entry
This happens because create_pending_snapshot() initializes the new root
item as a copy of the source root item. This includes the refs field,
which is 0 for a deleted subvolume. The call to btrfs_insert_root()
therefore inserts a root with refs == 0. btrfs_get_new_fs_root() then
finds the root and returns -ENOENT if refs == 0, which causes
create_pending_snapshot() to abort.
Fix it by checking the source root's refs before attempting the
snapshot, but after locking subvol_sem to avoid racing with deletion. |
| VMware ESXi, Workstation, Fusion, and VMware Tools contains an information disclosure vulnerability due to the usage of an uninitialised memory in vSockets. A malicious actor with local administrative privileges on a virtual machine may be able to exploit this issue to leak memory from processes communicating with vSockets. |
| ESPTouch is a connection protocol for internet of things devices. In the ESPTouchV2 protocol, while there is an option to use a custom AES key, there is no option to set the IV (Initialization Vector) prior to versions 5.3.2, 5.2.4, 5.1.6, and 5.0.8. The IV is set to zero and remains constant throughout the product's lifetime. In AES/CBC mode, if the IV is not properly initialized, the encrypted output becomes deterministic, leading to potential data leakage. To address the aforementioned issues, the application generates a random IV when activating the AES key starting in versions 5.3.2, 5.2.4, 5.1.6, and 5.0.8. This IV is then transmitted along with the provision data to the provision device. The provision device has also been equipped with a parser for the AES IV. The upgrade is applicable for all applications and users of ESPTouch v2 component from ESP-IDF. As it is implemented in the ESP Wi-Fi stack, there is no workaround for the user to fix the application layer without upgrading the underlying firmware. |
| The http parser in Phusion Passenger 6.0.21 through 6.0.25 before 6.0.26 allows a denial of service during parsing of a request with an invalid HTTP method. |
| ReadWPGImage in WPG in GraphicsMagick before 1.3.46 mishandles palette buffer allocation, resulting in out-of-bounds access to heap memory in ReadBlob. |
| Another “uninitialized variable” code execution vulnerability exists in the Rockwell Automation Arena® that could allow a threat actor to craft a DOE file and force the software to access a variable prior to it being initialized. If exploited, a threat actor could leverage this vulnerability to execute arbitrary code. To exploit this vulnerability, a legitimate user must execute the malicious code crafted by the threat actor. |
| An uninitialized resource in Ivanti EPM before the 2024 January-2025 Security Update and 2022 SU6 January-2025 Security Update allows a local authenticated attacker to escalate their privileges. |

| Use of uninitialized resource in Windows DWM Core Library allows an authorized attacker to disclose information locally. |
| In BnAudioPolicyService::onTransact of IAudioPolicyService.cpp, there is a possible information disclosure due to uninitialized data. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation. |

| In the Linux kernel, the following vulnerability has been resolved:
udf: Fix bogus checksum computation in udf_rename()
Syzbot reports uninitialized memory access in udf_rename() when updating
checksum of '..' directory entry of a moved directory. This is indeed
true as we pass on-stack diriter.fi to the udf_update_tag() and because
that has only struct fileIdentDesc included in it and not the impUse or
name fields, the checksumming function is going to checksum random stack
contents beyond the end of the structure. This is actually harmless
because the following udf_fiiter_write_fi() will recompute the checksum
from on-disk buffers where everything is properly included. So all that
is needed is just removing the bogus calculation. |
