https://notcve.org/view.php?id=CVE-2021-33656
When setting font with malicous data by ioctl cmd PIO_FONT,kernel will write memory out of bounds. Cuando es establecida la fuente con datos maliciosos por ioctl cmd PIO_FONT, el kernel escribirá memoria fuera de límites An out-of-bounds write flaw was found in the Linux kernel’s console driver functionality in the way a user triggers the ioctl PIO_FONT with malicious data. This flaw allows a local user to crash or potentially escalate their privileges on the system. • http://www.openwall.com/lists/oss-security/2022/07/19/3 https://git.kernel.org/pub/scm/linux/kernel/git/stable/stable-queue.git/tree/releases/5.10.127/vt-drop-old-font-ioctls.patch https://lists.debian.org/debian-lts-announce/2022/10/msg00000.html https://www.openeuler.org/en/security/cve/detail.html?id=CVE-2021-33656&packageName=kernel https://access.redhat.com/security/cve/CVE-2021-33656 https://bugzilla.redhat.com/show_bug.cgi?id=2108696 • CWE-787: Out-of-bounds Write •

CVSS: 8.2EPSS: 0%CPEs: 1EXPL: 0CVE-2022-2991 – Linux Kernel LightNVM Subsystem Heap-based Overflow Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2022-2991
A heap-based buffer overflow was found in the Linux kernel's LightNVM subsystem. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. This vulnerability allows a local attacker to escalate privileges and execute arbitrary code in the context of the kernel. The attacker must first obtain the ability to execute high-privileged code on the target system to exploit this vulnerability.

Additionally the granularity of the grant table doesn't allow sharing less than a 4K page, leading to unrelated data residing in the same 4K page as data shared with a backend being accessible by such backend (CVE-2022-33741, CVE-2022-33742).
