[CLSA-2026:1792483980] alt-python310: Fix of CVE-2026-7210
Type:
security
Severity:
None
Release date:
2026-10-20 08:13:08 UTC
Description:
- CVE-2026-7210: restore the weak-symbol detection of XML_SetHashSalt16Bytes in pyexpat, reduced to Modules/pyexpat.c on top of the upstream fix that 3.10.22 carries. Upstream selects the 16-byte Expat hash salt only when the libexpat header reports >= 2.8.0, but ELS libexpat on el8/el9 backports XML_SetHashSalt16Bytes without bumping its version macros, so 3.10.22-1 fell back to the 8-byte salt there. No-op on el7 (bundled libexpat 2.8.5) and on hosts whose libexpat does not export the function
