https://notcve.org/view.php?id=CVE-2022-2078
A vulnerability was found in the Linux kernel's nft_set_desc_concat_parse() function .This flaw allows an attacker to trigger a buffer overflow via nft_set_desc_concat_parse() , causing a denial of service and possibly to run code. Se ha encontrado una vulnerabilidad en la función nft_set_desc_concat_parse() del kernel de Linux. Este fallo permite a un atacante desencadenar un desbordamiento de búfer por medio de la función nft_set_desc_concat_parse() , causando una denegación de servicio y posiblemente una ejecución de código • https://github.com/delsploit/CVE-2022-2078 https://bugzilla.redhat.com/show_bug.cgi?id=2096178 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/net/netfilter/nf_tables_api.c?id=fecf31ee395b0295f2d7260aa29946b7605f7c85 https://www.debian.org/security/2022/dsa-5161 https://access.redhat.com/security/cve/CVE-2022-2078 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-121: Stack-based Buffer Overflow •

https://notcve.org/view.php?id=CVE-2022-1852
A NULL pointer dereference flaw was found in the Linux kernel’s KVM module, which can lead to a denial of service in the x86_emulate_insn in arch/x86/kvm/emulate.c. This flaw occurs while executing an illegal instruction in guest in the Intel CPU. Se ha encontrado un fallo de desreferencia de puntero NULL en el módulo KVM del kernel de Linux, que puede conllevar a una denegación de servicio en el archivo x86_emulate_insn en arch/x86/kvm/emulate.c.

CVSS: 6.9EPSS: 0%CPEs: 40EXPL: 0CVE-2021-3696 – grub2: Crafted PNG image may lead to out-of-bound write during huffman table handling
https://notcve.org/view.php?id=CVE-2021-3696
A heap out-of-bounds write may heppen during the handling of Huffman tables in the PNG reader. This may lead to data corruption in the heap space. Confidentiality, Integrity and Availablity impact may be considered Low as it's very complex to an attacker control the encoding and positioning of corrupted Huffman entries to achieve results such as arbitrary code execution and/or secure boot circumvention. This flaw affects grub2 versions prior grub-2.12. Puede producirse una escritura fuera de límites de la pila durante el manejo de las tablas Huffman en el lector PNG. • https://bugzilla.redhat.com/show_bug.cgi?id=1991686 https://security.gentoo.org/glsa/202209-12 https://security.netapp.com/advisory/ntap-20220930-0001 https://access.redhat.com/security/cve/CVE-2021-3696 • CWE-787: Out-of-bounds Write •
CVSS: 7.5EPSS: 0%CPEs: 39EXPL: 0CVE-2021-3697 – grub2: Crafted JPEG image can lead to buffer underflow write in the heap
https://notcve.org/view.php?id=CVE-2021-3697
A crafted JPEG image may lead the JPEG reader to underflow its data pointer, allowing user-controlled data to be written in heap. To a successful to be performed the attacker needs to perform some triage over the heap layout and craft an image with a malicious format and payload. This vulnerability can lead to data corruption and eventual code execution or secure boot circumvention. This flaw affects grub2 versions prior grub-2.12. Una imagen JPEG diseñada puede conllevar que el lector de JPEG desborde su puntero de datos, permitiendo que los datos controlados por el usuario sean escritos en la pila. • https://bugzilla.redhat.com/show_bug.cgi?id=1991687 https://security.gentoo.org/glsa/202209-12 https://security.netapp.com/advisory/ntap-20220930-0001 https://access.redhat.com/security/cve/CVE-2021-3697 • CWE-787: Out-of-bounds Write •
CVSS: 7.5EPSS: 0%CPEs: 41EXPL: 0CVE-2021-3695 – grub2: Crafted PNG grayscale images may lead to out-of-bounds write in heap
https://notcve.org/view.php?id=CVE-2021-3695
A crafted 16-bit grayscale PNG image may lead to a out-of-bounds write in the heap area. An attacker may take advantage of that to cause heap data corruption or eventually arbitrary code execution and circumvent secure boot protections. This issue has a high complexity to be exploited as an attacker needs to perform some triage over the heap layout to achieve signifcant results, also the values written into the memory are repeated three times in a row making difficult to produce valid payloads. This flaw affects grub2 versions prior grub-2.12. Una imagen PNG en escala de grises de 16 bits diseñada puede conllevar a una escritura fuera de límites en el área de la pila. • https://bugzilla.redhat.com/show_bug.cgi?id=1991685 https://security.gentoo.org/glsa/202209-12 https://security.netapp.com/advisory/ntap-20220930-0001 https://access.redhat.com/security/cve/CVE-2021-3695 • CWE-787: Out-of-bounds Write •
