CVE-2026-25210: Integer Overflow or Wraparound

In libexpat before 2.7.4, the doContent function does not properly determine the buffer size bufSize because there is no integer overflow check for tag buffer reallocation...

PT-2026-5383

Name of the Vulnerable Software and Affected Versions libexpat versions prior to 2.7.4 Description The doContent function in libexpat does not correctly calculate the buffer size bufSize when reallocating memory for tags, due to a missing integer overflow check. This can lead to potential issues...

CVE-2025-48769

Use After Free vulnerability was discovered in fs/vfs/fsrename code of the Apache NuttX RTOS, that due recursive implementation and single buffer use by two different pointer variables allowed arbitrary user provided size buffer reallocation and write to the previously freed heap chunk, that in...

CVE-2025-48769

CVE-2025-48769 affects Apache NuttX RTOS. The flaw is a Use-After-Free in the fs/vfs/fs_rename code caused by a recursive implementation reusing a single buffer across two pointers, enabling arbitrary user-provided buffer reallocations and writes to a freed heap chunk. In affected scenarios, this...

CVE-2022-50679

CVE-2022-50679 concerns the Linux kernel i40e driver, where DMA mappings leak during RX buffer reallocation. The root cause is that new DMA mappings are created for buffers when reconfiguring RX rings, leading to leaks when old buffers are freed and DMA mappings are freed incorrectly. This can ca...
