Title
Arbitrary Memory Disclosure through CPU Side-Channel Attacks (Retbleed)
Summary
Intel microprocessor generations 6 to 8 are affected by a new Spectre variant that is able to bypass their retpoline mitigation in the kernel to leak arbitrary data. An attacker with unprivileged user access can hijack return instructions to achieve arbitrary speculative code execution under certain microarchitecture-dependent conditions.
Severity

CVE-2022-33740 (GCVE-0-2022-33740)
Vulnerability from cvelistv5 – Published: 2022-07-05 12:50 – Updated: 2024-08-03 08:09
VLAI
EPSS
Summary
Linux disk/nic frontends data leaks T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Linux Block and Network PV device frontends don't zero memory regions before sharing them with the backend (CVE-2022-26365, CVE-2022-33740). 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).

No CVSS data available.

CVE-2022-34918 (GCVE-0-2022-34918)
Vulnerability from cvelistv5 – Published: 2022-07-04 20:07 – Updated: 2024-08-03 09:22
VLAI
EPSS
Summary
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.
Severity
No CVSS data available.
