Alpine: multiple swtpm packages: security update to 0.10.2

medium Tenable Cloud Security Plugin ID 446107

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- An out-of-bounds read vulnerability was found in swtpm's SWTPM_NVRAM_CheckHeader() function. The entry
guard checks the buffer length against sizeof(bh), where bh is a pointer, instead of sizeof(*bh), the
actual struct size. This allows an undersized buffer to pass validation, causing a 2-byte heap overread on
64-bit systems (6 bytes on 32-bit) when accessing the totlen field. This may cause daemon termination on
some platforms and leaks heap data to the log. (CVE-2026-75900)

Solution

Update the swtpm library and its related packages to version 0.10.2 or later.
