postgresql: PostgreSQL libpq: Buffer overflow allows server superuser to overwrite client stack memory

A flaw was found in PostgreSQL libpq. A server superuser can exploit a buffer overflow vulnerability in the PQfn function, which is used by client functions such as loexport, loread, lolseek64, and lotell64. This allows the superuser to send an arbitrarily large response, overwriting the client's...

CVE-2026-6687

FatFs R0.16 and earlier contains a stack overflow bug in fgetlabel because exFAT label length XDIRNumLabel is trusted without enforcing spec maximums. This maps to CWE-121 Stack-based Buffer Overflow. Estimated CVSS v3.1 vector: CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H 7.6, High. The estimate...
