| In the Linux kernel, the following vulnerability has been resolved:
drm/xe/ufence: Prefetch ufence addr to catch bogus address
access_ok() only checks for addr overflow so also try to read the addr
to catch invalid addr sent from userspace.

| In the Linux kernel, the following vulnerability has been resolved:
media: vivid: fix buffer overwrite when using > 32 buffers
The maximum number of buffers that can be requested was increased to
64 for the video capture queue. But video capture used a must_blank
array that was still sized for 32 (VIDEO_MAX_FRAME). This caused an
out-of-bounds write when using buffer indices >= 32.
Create a new define MAX_VID_CAP_BUFFERS that is used to access the
must_blank array and set max_num_buffers for the video capture queue.
This solves a crash reported by:

| In the Linux kernel, the following vulnerability has been resolved:
net: ethernet: mtk_eth_soc: fix memory corruption during fq dma init
The loop responsible for allocating up to MTK_FQ_DMA_LENGTH buffers must
only touch as many descriptors, otherwise it ends up corrupting unrelated
memory. Fix the loop iteration count accordingly. |
| In the Linux kernel, the following vulnerability has been resolved:
net: pse-pd: Fix out of bound for loop
Adjust the loop limit to prevent out-of-bounds access when iterating over
PI structures. The loop should not reach the index pcdev->nr_lines since
we allocate exactly pcdev->nr_lines number of PI structures. This fix
ensures proper bounds are maintained during iterations. |
| A vulnerability, which was classified as problematic, was found in mruby up to 3.4.0-rc2. Affected is the function scope_new of the file mrbgems/mruby-compiler/core/codegen.c of the component nregs Handler. The manipulation leads to heap-based buffer overflow. An attack has to be approached locally. The exploit has been disclosed to the public and may be used. The name of the patch is 1fdd96104180cc0fb5d3cb086b05ab6458911bb9. It is recommended to apply a patch to fix this issue. |
| spimsimulator spim v9.1.24 and before is vulnerable to Buffer Overflow in READ_STRING_SYSCALL. |
| In the Linux kernel, the following vulnerability has been resolved:
nvme-tcp: fix potential memory corruption in nvme_tcp_recv_pdu()
nvme_tcp_recv_pdu() doesn't check the validity of the header length.
When header digests are enabled, a target might send a packet with an
invalid header length (e.g. 255), causing nvme_tcp_verify_hdgst()
to access memory outside the allocated area and cause memory corruptions
by overwriting it with the calculated digest.
Fix this by rejecting packets with an unexpected header length. |
| In the Linux kernel, the following vulnerability has been resolved:
net: hns3: fixed hclge_fetch_pf_reg accesses bar space out of bounds issue
The TQP BAR space is divided into two segments. TQPs 0-1023 and TQPs
1024-1279 are in different BAR space addresses. However,
hclge_fetch_pf_reg does not distinguish the tqp space information when
reading the tqp space information. When the number of TQPs is greater
than 1024, access bar space overwriting occurs.
The problem of different segments has been considered during the
initialization of tqp.io_base. Therefore, tqp.io_base is directly used
when the queue is read in hclge_fetch_pf_reg.
The error message:
Unable to handle kernel paging request at virtual address ffff800037200000

mailbox: th1520: Fix memory corruption due to incorrect array size
The functions th1520_mbox_suspend_noirq and th1520_mbox_resume_noirq are
intended to save and restore the interrupt mask registers in the MBOX
ICU0. However, the array used to store these registers was incorrectly
sized, leading to memory corruption when accessing all four registers.
This commit corrects the array size to accommodate all four interrupt
mask registers, preventing memory corruption during suspend and resume
operations. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Adding array index check to prevent memory corruption
[Why & How]
Array indices out of bound caused memory corruption. Adding checks to
ensure that array index stays in bound. |
| In the Linux kernel, the following vulnerability has been resolved:
nfs/localio: must clear res.replen in nfs_local_read_done
Otherwise memory corruption can occur due to NFSv3 LOCALIO reads
leaving garbage in res.replen:
- nfs3_read_done() copies that into server->read_hdrsize; from there
nfs3_proc_read_setup() copies it to args.replen in new requests.
- nfs3_xdr_enc_read3args() passes that to rpc_prepare_reply_pages()
which includes it in hdrsize for xdr_init_pages, so that rq_rcv_buf
contains a ridiculous len.
- This is copied to rq_private_buf and xs_read_stream_request()
eventually passes the kvec to sock_recvmsg() which receives incoming
data into entirely the wrong place.
This is easily reproduced with NFSv3 LOCALIO that is servicing reads
when it is made to pivot back to using normal RPC. This switch back
to using normal NFSv3 with RPC can occur for a few reasons but this
issue was exposed with a test that stops and then restarts the NFSv3
server while LOCALIO is performing heavy read IO. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Use dynamic allocation for CU occupancy array in 'kfd_get_cu_occupancy()'
The `kfd_get_cu_occupancy` function previously declared a large
`cu_occupancy` array as a local variable, which could lead to stack
overflows due to excessive stack usage. This commit replaces the static
array allocation with dynamic memory allocation using `kcalloc`,
thereby reducing the stack size.
This change avoids the risk of stack overflows in kernel space, in
scenarios where `AMDGPU_MAX_QUEUES` is large. The allocated memory is
freed using `kfree` before the function returns to prevent memory
leaks.
Fixes the below with gcc W=1:
drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_process.c: In function ‘kfd_get_cu_occupancy’:
drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_process.c:322:1: warning: the frame size of 1056 bytes is larger than 1024 bytes [-Wframe-larger-than=]

| In the Linux kernel, the following vulnerability has been resolved:
clk: clk-loongson2: Fix memory corruption bug in struct loongson2_clk_provider
Some heap space is allocated for the flexible structure `struct
clk_hw_onecell_data` and its flexible-array member `hws` through
the composite structure `struct loongson2_clk_provider` in function
`loongson2_clk_probe()`, as shown below:
289 struct loongson2_clk_provider *clp;
...
296 for (p = data; p->name; p++)
297 clks_num++;
298
299 clp = devm_kzalloc(dev, struct_size(clp, clk_data.hws, clks_num),
300 GFP_KERNEL);
Then some data is written into the flexible array:
350 clp->clk_data.hws[p->id] = hw;
This corrupts `clk_lock`, which is the spinlock variable immediately
following the `clk_data` member in `struct loongson2_clk_provider`:
struct loongson2_clk_provider {
void __iomem *base;
struct device *dev;
struct clk_hw_onecell_data clk_data;
spinlock_t clk_lock; /* protect access to DIV registers */
};
The problem is that the flexible structure is currently placed in the
middle of `struct loongson2_clk_provider` instead of at the end.
Fix this by moving `struct clk_hw_onecell_data clk_data;` to the end of
`struct loongson2_clk_provider`. Also, add a code comment to help
prevent this from happening again in case new members are added to the
structure in the future.
This change also fixes the following -Wflex-array-member-not-at-end
warning:
drivers/clk/clk-loongson2.c:32:36: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] |
