UBUNTU-CVE-2026-9648

The crypton-x509-validation Haskell library fails to enforce X.509 NameConstraints, allowing TLS clients to accept certificates whose Subject Alternative Names fall outside the issuing CA’s permitted subtrees. This oversight enables an attacker who compromises a name-constrained sub-CA to...

Erlang/OTP -- TLS hostname verification bypass via Subject CommonName fallback and name constraints

https://github.com/erlang/otp/security/advisories/GHSA-22cw-4ph4-6447 reports: Erlang/OTP's TLS hostname verification implements a legacy RFC 6125 fallback that checks the Subject CommonName when the Subject Alternative Name SAN extension is absent, rather than following RFC 9525 which requires...

CVE-2026-23250

CVE-2026-23250 is a Linux kernel vulnerability in the XFS code path. The issue arises from not checking the return value of xchk_scrub_create_subord, which could yield an ENOMEM mangling the flow. The fix updates xchk_scrub_create_subord to return NULL on allocation failure and adjusts callers to...

CVE-2026-23250 xfs: check return value of xchk_scrub_create_subord

In the Linux kernel, the following vulnerability has been resolved: xfs: check return value of xchkscrubcreatesubord Fix this function to return NULL instead of a mangled ENOMEM, then fix the callers to actually check for a null pointer and return ENOMEM. Most of the corrections here are for code...
