CVE-2026-75900

An out-of-bounds read vulnerability was found in swtpm's SWTPMNVRAMCheckHeader function. The entry guard checks the buffer length against sizeofbh, where bh is a pointer, instead of sizeofbh, the actual struct size. This allows an undersized buffer to pass validation, causing a 2-byte heap overre...

CVE-2026-75900

swtpm's SWTPM_NVRAM_CheckHeader() validates buffer length against sizeof(pointer) instead of sizeof(struct), allowing an undersized buffer to pass and cause a 2-byte heap overread (6 bytes on 32-bit). Impact: daemon termination and heap data leakage to logs. Red Hat reports no mitigation; fixed i...
