An issue was discovered in the Linux kernel through 5.18.14. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity.
In addition to the c_rehash shell command injection identified in CVE-2022-1292, further circumstances where the c_rehash script does not properly sanitise shell metacharacters to prevent command. Rated high severity (CVSS 7.3), this vulnerability is low attack complexity. This OS Command Injection vulnerability could allow attackers to execute arbitrary operating system commands on the host.
The OPENSSL_LH_flush() function, which empties a hash table, contains a bug that breaks reuse of the memory occuppied by the removed hash table entries. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
The OpenSSL 3.0 implementation of the RC4-MD5 ciphersuite incorrectly uses the AAD data as the MAC key. Rated medium severity (CVSS 5.9), this vulnerability is remotely exploitable, no authentication required. No vendor patch available.
The function `OCSP_basic_verify` verifies the signer certificate on an OCSP response. Rated medium severity (CVSS 5.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
The c_rehash script does not properly sanitise shell metacharacters to prevent command injection. Rated high severity (CVSS 7.3), this vulnerability is low attack complexity. No vendor patch available.
Memory leak in icmp6 implementation in Linux Kernel 5.13+ allows a remote attacker to DoS a host by making it go out-of-memory via icmp6 packets of type 130 or 131. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity.
Use-after-free vulnerability in fs/block_dev.c in the Linux kernel before 5.8 allows local users to gain privileges or cause a denial of service by leveraging improper access to a certain error field. Rated medium severity (CVSS 6.7), this vulnerability is low attack complexity. Public exploit code available and no vendor patch available.
A flaw was found in the Linux kernel's implementation of Userspace core dumps. Rated medium severity (CVSS 4.4), this vulnerability is low attack complexity. This Use of Uninitialized Resource vulnerability could allow attackers to access uninitialized memory causing crashes or information disclosure.
The fix for the Linux kernel in Ubuntu 18.04 LTS for CVE-2019-14615 ("The Linux kernel did not properly clear data structures on context switches for certain Intel graphics processors.") was. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity. No vendor patch available.
In the Linux kernel 5.0.21 and 5.3.11, mounting a crafted btrfs filesystem image, performing some operations, and then making a syncfs system call can lead to a use-after-free in try_merge_free_space. Rated high severity (CVSS 7.8), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
