| In the Linux kernel, the following vulnerability has been resolved:
gpio: gpio-xilinx: Fix integer overflow
Current implementation is not able to configure more than 32 pins
due to incorrect data type. So type casting with unsigned long
to avoid it. |
| In the Linux kernel, the following vulnerability has been resolved:
watchdog: rzg2l_wdt: Fix 32bit overflow issue
The value of timer_cycle_us can be 0 due to 32bit overflow.
For eg:- If we assign the counter value "0xfff" for computing
maxval.
This patch fixes this issue by appending ULL to 1024, so that
it is promoted to 64bit.
This patch also fixes the warning message, 'watchdog: Invalid min and
max timeout values, resetting to 0!'. |
| In the Linux kernel, the following vulnerability has been resolved:
cpufreq: CPPC: Add u64 casts to avoid overflowing
The fields of the _CPC object are unsigned 32-bits values.
To avoid overflows while using _CPC's values, add 'u64' casts. |
| In the Linux kernel, the following vulnerability has been resolved:
i2c: designware: use casting of u64 in clock multiplication to avoid overflow
In functions i2c_dw_scl_lcnt() and i2c_dw_scl_hcnt() may have overflow
by depending on the values of the given parameters including the ic_clk.
For example in our use case where ic_clk is larger than one million,
multiplication of ic_clk * 4700 will result in 32 bit overflow.
Add cast of u64 to the calculation to avoid multiplication overflow, and
use the corresponding define for divide. |
| In the Linux kernel, the following vulnerability has been resolved:
perf/x86/amd: fix potential integer overflow on shift of a int
The left shift of int 32 bit integer constant 1 is evaluated using 32 bit
arithmetic and then passed as a 64 bit function argument. In the case where
i is 32 or more this can lead to an overflow. Avoid this by shifting
using the BIT_ULL macro instead. |
| In the Linux kernel, the following vulnerability has been resolved:
ACPI: APEI: Fix integer overflow in ghes_estatus_pool_init()
Change num_ghes from int to unsigned int, preventing an overflow
and causing subsequent vmalloc() to fail.
The overflow happens in ghes_estatus_pool_init() when calculating
len during execution of the statement below as both multiplication
operands here are signed int:
len += (num_ghes * GHES_ESOURCE_PREALLOC_MAX_SIZE);
The following call trace is observed because of this bug:

| In the Linux kernel, the following vulnerability has been resolved:
drm/xe/xe_migrate: Cast to output precision before multiplying operands
Addressing potential overflow in result of multiplication of two lower
precision (u32) operands before widening it to higher precision
(u64).
-v2
Fix commit message and description. (Rodrigo)
(cherry picked from commit 34820967ae7b45411f8f4f737c2d63b0c608e0d7) |
| In SQLite 3.49.0 before 3.49.1, certain argument values to sqlite3_db_config (in the C-language API) can cause a denial of service (application crash). An sz*nBig multiplication is not cast to a 64-bit integer, and consequently some memory allocations may be incorrect. |
| The Treck TCP/IP stack before 6.0.1.66 has an Integer Overflow during Memory Allocation that causes an Out-of-Bounds Write. |
| FCGI versions 0.44 through 0.82, for Perl, include a vulnerable version of the FastCGI fcgi2 (aka fcgi) library.
The included FastCGI library is affected by CVE-2025-23016, causing an integer overflow (and resultant heap-based buffer overflow) via crafted nameLen or valueLen values in data to the IPC socket. This occurs in ReadParams in fcgiapp.c. |
| In Artifex Ghostscript through 10.05.1, ocr_begin_page in devices/gdevpdfocr.c has an integer overflow that leads to a heap-based buffer overflow in ocr_line8. |
| An integer overflow in WhatsApp could result in remote code execution in an established video call. |
| In the Linux kernel, the following vulnerability has been resolved:
af_netlink: Fix shift out of bounds in group mask calculation
When a netlink message is received, netlink_recvmsg() fills in the address
of the sender. One of the fields is the 32-bit bitfield nl_groups, which
carries the multicast group on which the message was received. The least
significant bit corresponds to group 1, and therefore the highest group
that the field can represent is 32. Above that, the UB sanitizer flags the
out-of-bounds shift attempts.
Which bits end up being set in such case is implementation defined, but
it's either going to be a wrong non-zero value, or zero, which is at least
not misleading. Make the latter choice deterministic by always setting to 0
for higher-numbered multicast groups.
To get information about membership in groups >= 32, userspace is expected
to use nl_pktinfo control messages[0], which are enabled by NETLINK_PKTINFO
socket option.

The way to trigger this issue is e.g. through monitoring the BRVLAN group:
# bridge monitor vlan &
# ip link add name br type bridge
Which produces the following citation:
UBSAN: shift-out-of-bounds in net/netlink/af_netlink.c:162:19
shift exponent 32 is too large for 32-bit type 'int' |

drm/bridge: anx7625: Fix overflow issue on reading EDID
The length of EDID block can be longer than 256 bytes, so we should use
`int` instead of `u8` for the `edid_pos` variable. |
| Ashlar-Vellum Cobalt VC6 File Parsing Integer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Ashlar-Vellum Cobalt. 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 validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-25704. |
| Ashlar-Vellum Cobalt LI File Parsing Integer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Ashlar-Vellum Cobalt. 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 LI files. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-25476. |
| In the Linux kernel, the following vulnerability has been resolved:
dmaengine: zynqmp_dma: In struct zynqmp_dma_chan fix desc_size data type
In zynqmp_dma_alloc/free_chan_resources functions there is a
potential overflow in the below expressions.
dma_alloc_coherent(chan->dev, (2 * chan->desc_size *
ZYNQMP_DMA_NUM_DESCS),
&chan->desc_pool_p, GFP_KERNEL);
dma_free_coherent(chan->dev,(2 * ZYNQMP_DMA_DESC_SIZE(chan) *
ZYNQMP_DMA_NUM_DESCS),
chan->desc_pool_v, chan->desc_pool_p);
The arguments desc_size and ZYNQMP_DMA_NUM_DESCS were 32 bit. Though
this overflow condition is not observed but it is a potential problem
in the case of 32-bit multiplication. Hence fix it by changing the
desc_size data type to size_t.
In addition to coverity fix it also reuse ZYNQMP_DMA_DESC_SIZE macro in
dma_alloc_coherent API argument.
Addresses-Coverity: Event overflow_before_widen. |
| NVIDIA Triton Inference Server contains a vulnerability in the model loading API, where a user could cause an integer overflow or wraparound error by loading a model with an extra-large file size that overflows an internal variable. A successful exploit of this vulnerability might lead to denial of service. |
| WebAssembly Micro Runtime (WAMR) is a lightweight standalone WebAssembly (Wasm) runtime. In WAMR versions prior to 2.4.2, when running in LLVM-JIT mode, the runtime cannot exit normally when executing WebAssembly programs containing a memory.fill instruction where the first operand (memory address pointer) is greater than or equal to 2147483648 bytes (2GiB). This causes the runtime to hang in release builds or crash in debug builds due to accessing an invalid pointer. The issue does not occur in FAST-JIT mode or other runtime tools. This has been fixed in version 2.4.2. |
| In the Linux kernel, the following vulnerability has been resolved:
block: fix overflow in blk_ioctl_discard()
There is no check for overflow of 'start + len' in blk_ioctl_discard().
Hung task occurs if submit an discard ioctl with the following param:
start = 0x80000000000ff000, len = 0x8000000000fff000;
Add the overflow validation now. |
