An issue was discovered in the Linux kernel through 5.18.3 on powerpc 32-bit platforms. There is a buffer overflow in ptrace PEEKUSER and POKEUSER (aka PEEKUSR and POKEUSR) when accessing floating point registers. Se ha detectado un problema en el kernel de Linux versiones hasta 5.18.3, en plataformas powerpc de 32 bits.

CVSS: 8.2EPSS: 0%CPEs: 7EXPL: 0CVE-2022-1012 – kernel: Small table perturb size in the TCP source port generation algorithm can lead to information leak
https://notcve.org/view.php?id=CVE-2022-1012
A memory leak problem was found in the TCP source port generation algorithm in net/ipv4/tcp.c due to the small table perturb size. This flaw may allow an attacker to information leak and may cause a denial of service problem. Se ha encontrado un problema de pérdida de memoria en el algoritmo de generación de puertos de origen TCP en el archivo net/ipv4/tcp.c debido al pequeño tamaño de la tabla de perturbación. Este fallo puede permitir a un atacante un filtrado de información y puede causar un problema de denegación de servicio The Linux kernel's TCP source port generation algorithm in the TCP stack contains a flaw due to the small table perturb size. This flaw allows an attacker to positively distinguish a system among devices with identical hardware and software, which lasts until the device restarts. An attacker can guess the evolution of the internal state used for source port generation. • https://bugzilla.redhat.com/show_bug.cgi?id=2064604 https://lore.kernel.org/lkml/20220427065233.2075-1-w%401wt.eu/T https://security.netapp.com/advisory/ntap-20221020-0006 https://access.redhat.com/security/cve/CVE-2022-1012 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-401: Missing Release of Memory after Effective Lifetime •
