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-2026-63934

A flaw was found in the Linux kernel's iioitg3200 gyroscope driver. An incorrect I2C Inter-Integrated Circuit read operation in the itg3200readallchannels function causes uninitialized stack memory to be exposed to userspace. This information leak could allow a local attacker to gain access to...
