18 Jul 2022 — 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 • CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2022-2991
11 Jul 2022 — 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.

05 Jul 2022 — Arm guests can cause Dom0 DoS via PV devices When mapping pages of guests on Arm, dom0 is using an rbtree to keep track of the foreign mappings. Updating of that rbtree is not always done completely with the related lock held, resulting in a small race window, which can be used by unprivileged guests via PV devices to cause inconsistencies of the rbtree. These inconsistencies can lead to Denial of Service (DoS) of dom0, e.g. by causing crashes or the inability to perform further mappings of other guests' me... • http://www.openwall.com/lists/oss-security/2022/07/05/4 •
CVSS: 7.8EPSS: 0%CPEs: 22EXPL: 9CVE-2022-34918 – kernel: heap overflow in nft_set_elem_init()
https://notcve.org/view.php?id=CVE-2022-34918
04 Jul 2022 — An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data in net/netfilter/nf_tables_api.c. Se ha detectado un problema en el kernel de Linux versiones hasta 5.18.9. • https://github.com/veritas501/CVE-2022-34918 • CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') CWE-1025: Comparison Using Wrong Factors •
