| CVE-2023-31248 | Hig | 0.51 | 7.8 | 0.02 | Jul 5, 2023 | Linux Kernel nftables Use-After-Free Local Privilege Escalation Vulnerability; `nft_chain_lookup_byid()` failed to check whether a chain was active and CAP_NET_ADMIN is in any user or network namespace | ||
| CVE-2023-35788 | Hig | 0.51 | 7.8 | 0.01 | Jun 16, 2023 | An issue was discovered in fl_set_geneve_opt in net/sched/cls_flower.c in the Linux kernel before 6.3.7. It allows an out-of-bounds write in the flower classifier code via TCA_FLOWER_KEY_ENC_OPTS_GENEVE packets. This may result in denial of service or privilege escalation. | ||
| CVE-2023-0179 | Hig | 0.51 | 7.8 | 0.02 | Mar 27, 2023 | A buffer overflow vulnerability was found in the Netfilter subsystem in the Linux Kernel. This issue could allow the leakage of both stack and heap addresses, and potentially allow Local Privilege Escalation to the root user via arbitrary code execution. | ||
| CVE-2022-1055 | Hig | 0.51 | 7.8 | 0.01 | Mar 29, 2022 | A use-after-free exists in the Linux Kernel in tc_new_tfilter that could allow a local attacker to gain privilege escalation. The exploit requires unprivileged user namespaces. We recommend upgrading past commit 04c2a47ffb13c29778e2a14e414ad4cb5a5db4b5 | ||
| CVE-2021-44731 | Hig | 0.51 | 7.8 | 0.01 | Feb 17, 2022 | A race condition existed in the snapd 2.54.2 snap-confine binary when preparing a private mount namespace for a snap. This could allow a local attacker to gain root privileges by bind-mounting their own contents inside the snap's private mount namespace and causing snap-confine… | ||
| CVE-2021-44730 | Hig | 0.51 | 7.8 | 0.00 | Feb 17, 2022 | snapd 2.54.2 did not properly validate the location of the snap-confine binary.
