CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
drm/virtio: Ensure that objs is not NULL in virtio_gpu_array_put_free()
If virtio_gpu_object_shmem_init() fails (e.g. due to fault injection, as it
happened in the bug report by syzbot), virtio_gpu_array_put_free() could be
called with objs equal to NULL.
Ensure that objs is not NULL in virtio_gpu_array_put_free(), or otherwise
return from the function. |
| In the Linux kernel, the following vulnerability has been resolved:
media: venus: vdec: fixed possible memory leak issue
The venus_helper_alloc_dpb_bufs() implementation allows an early return
on an error path when checking the id from ida_alloc_min() which would
not release the earlier buffer allocation.
Move the direct kfree() from the error checking of dma_alloc_attrs() to
the common fail path to ensure that allocations are released on all
error paths in this function.
Addresses-Coverity: 1494120 ("Resource leak") |
| In the Linux kernel, the following vulnerability has been resolved:
samples/landlock: Fix path_list memory leak
Clang static analysis reports this error
sandboxer.c:134:8: warning: Potential leak of memory
pointed to by 'path_list'
ret = 0;
^
path_list is allocated in parse_path() but never freed. |

video: fbdev: smscufx: Fix null-ptr-deref in ufx_usb_probe()
I got a null-ptr-deref report:
BUG: kernel NULL pointer dereference, address: 0000000000000000
...
RIP: 0010:fb_destroy_modelist+0x38/0x100

If fb_alloc_cmap() fails in ufx_usb_probe(), fb_destroy_modelist() will
be called to destroy modelist in the error handling path. But modelist
has not been initialized yet, so it will result in null-ptr-deref.
Initialize modelist before calling fb_alloc_cmap() to fix this bug. |
| In the Linux kernel, the following vulnerability has been resolved:
soc: qcom: rpmpd: Check for null return of devm_kcalloc
Because of the possible failure of the allocation, data->domains might
be NULL pointer and will cause the dereference of the NULL pointer
later.
Therefore, it might be better to check it and directly return -ENOMEM
without releasing data manually if fails, because the comment of the
devm_kmalloc() says "Memory allocated with this function is
automatically freed on driver detach.". |
| In the Linux kernel, the following vulnerability has been resolved:
gpu: host1x: Fix a memory leak in 'host1x_remove()'
Add a missing 'host1x_channel_list_free()' call in the remove function,
as already done in the error handling path of the probe function. |
| In the Linux kernel, the following vulnerability has been resolved:
media: staging: media: zoran: calculate the right buffer number for zoran_reap_stat_com
On the case tmp_dcim=1, the index of buffer is miscalculated.
This generate a NULL pointer dereference later.
So let's fix the calcul and add a check to prevent this to reappear. |
| In the Linux kernel, the following vulnerability has been resolved:
media: staging: media: zoran: move videodev alloc
Move some code out of zr36057_init() and create new functions for handling
zr->video_dev. This permit to ease code reading and fix a zr->video_dev
memory leak. |

powerpc/kasan: Fix early region not updated correctly
The shadow's page table is not updated when PTE_RPN_SHIFT is 24
and PAGE_SHIFT is 12. It not only causes false positives but
also false negative as shown the following text.
Fix it by bringing the logic of kasan_early_shadow_page_entry here.

Reproducer (Detail program in [Link]):
1. SYS_renameat2("/mp/dir/file", "/mp/dir/whiteout", RENAME_WHITEOUT)
2. Consume out of space before kernel(mdelay) doing budget for whiteout
Fix it by doing whiteout space budget before locking ubifs inodes.
BTW, it also fixes wrong goto tag 'out_release' in whiteout budget
error handling path(It should at least recover dir i_size and unlock
4 ubifs inodes). |

bytes aligned, the 'len' represents the true length of buf (which is
allocated in 'ubifs_jnl_xxx', eg. ubifs_jnl_write_inode), so
ubifs_wbuf_write_nolock() must handle the length read from 'buf' carefully
to write leb safely.

| D-Link DSL-7740C with firmware DSL7740C.V6.TR069.20211230 was discovered to contain a command injection vulnerability via the ping6 function. |
| alextselegidis Easy!Appointments v1.5.1 was discovered to contain a SQL injection vulnerability via the order_by parameter. |
| NVIDIA NeMo Curator for all platforms contains a vulnerability where a malicious file created by an attacker could allow code injection. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, information disclosure, and data tampering. |
| A vulnerability classified as problematic was found in NOYAFA/Xiami LF9 Pro up to 20250611. Affected by this vulnerability is an unknown functionality of the component RTSP Live Video Stream Endpoint. The manipulation leads to improper access controls. The attack can only be initiated within the local network. The exploit has been disclosed to the public and may be used. This dashcam is distributed by multiple resellers and different names. |
| A vulnerability, which was classified as critical, has been found in xxyopen/201206030 novel-plus up to 5.1.3. Affected by this issue is the function ajaxLogin of the file novel-admin/src/main/java/com/java2nb/system/controller/LoginController.java of the component CATCHA Handler. The manipulation leads to authentication bypass by capture-replay. The attack may be launched remotely. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way. |
| A vulnerability was found in oatpp Oat++ up to 1.3.1. It has been declared as critical. This vulnerability affects the function deserializeArray of the file src/oatpp/json/Deserializer.cpp. The manipulation leads to stack-based buffer overflow. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. |
