UBUNTU-CVE-2026-73193

DBI versions before 1.652 for Perl allow a heap out-of-bounds write on 32-bit perl via an integer wraparound in the output buffer size computed by preparse. preparse reserves its output buffer with newSVstrlenstatement 7 + 16, budgeting seven output bytes per input byte for the longest ':p99999'...

CVE-2026-74469

In the Linux kernel, the following vulnerability has been resolved: sctp: prevent peer transport count overflow sctpassocaddpeer increments the association's 16-bit transportcount for every new unique peer. Adding the 65,536th transport wraps the count to zero. SCTP sockdiag uses transportcount t...

CVE-2026-74470

In the Linux kernel, the following vulnerability has been resolved: scsi: scsidebug: Fix REPORT ZONES alloclen underflow OOB write respreportzones sizes the reply buffer from the CDB allocation length. The v3 fix rounds alloclen up with ALIGN before deriving the descriptor count: repmaxzones =...

UBUNTU-CVE-2026-73194

DBI versions before 1.652 for Perl allow a heap out-of-bounds write via an unvalidated numeric placeholder that sets the binder counter in preparse. preparse reserves seven output bytes per input byte, the width of the longest ':p99999' expansion. The ':N' branch parses the number with atoisrc an...

CVE-2026-74570

CVE-2026-74570 is a Linux kernel vulnerability affecting NTFS runlist handling. The issue stems from unsafe/overflow-prone size calculations in runlist element counts used by ntfs_rl_realloc() and ntfs_rl_realloc_nofail(). A fix was implemented by adding a shared helper to safely convert runlist ...
