CVE-2023-54056

In the Linux kernel, the following vulnerability has been resolved: kheaders: Use array declaration instead of char Under CONFIGFORTIFYSOURCE, memcpy will check the size of destination and source buffers. Defining kernelheadersdata as "char" would trip this check. Since these addresses are treate...

CVE-2023-54056

The CVE-2023-54056 entry concerns the Linux kernel kheaders path. The underlying issue was that kernel_headers_data was defined as a char array, which trips FortifySource checks during memcpy by treating addresses as byte arrays; the fix is to define them as proper arrays (as with other code path...

In the Linux kernel, the following vulnerability has been resolved: can: j1939: j1939tptxdatnew: fix out-of-bounds memory access In the j1939tptxdatnew function, an out-of-bounds memory access could occur during the memcpy operation if the size of skb-cb is larger than the size of struct...

CVE-2023-54039

The CVE-2023-54039 issue is in the Linux kernel’s CAN J1939 code, specifically j1939_tp_tx_dat_new(). The vulnerability arises when a memcpy uses skb->cb’s size, allowing an out-of-bounds read if skb->cb is larger than struct j1939_sk_buff_cb. The fix changes memcpy to use the size of struc...

EUVD-2025-203996

Capstone is a disassembly framework. In versions 6.0.0-Alpha5 and prior, Skipdata length is not bounds-checked, so a user-provided skipdata callback can make csdisasm/csdisasmiter memcpy more than 24 bytes into csinsn.bytes, causing a heap buffer overflow in the disassembly path. Commit...

CVE-2025-67873

Capstone CVE-2025-67873 affects the disassembly framework in 6.0.0-Alpha5 and earlier. A missing bounds check on a user-provided skipdata callback allows memcpy beyond 24 bytes into cs_insn.bytes, causing a heap buffer overflow in the disassembly path. The exploit path and impact are described in...
