CVE-2022-47939 – Linux Kernel ksmbd Use-After-Free Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2022-47939
22 Dec 2022 — An issue was discovered in ksmbd in the Linux kernel 5.15 through 5.19 before 5.19.2. fs/ksmbd/smb2pdu.c has a use-after-free and OOPS for SMB2_TREE_DISCONNECT. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Linux Kernel. Authentication is not required to exploit this vulnerability, but only systems with ksmbd enabled are vulnerable. The specific flaw exists within the processing of SMB2_TREE_DISCONNECT commands. The issue results from the lack of validatin... • http://www.openwall.com/lists/oss-security/2022/12/23/10 • CWE-416: Use After Free •
CVE-2022-47941 – Linux Kernel ksmbd Memory Exhaustion Denial-of-Service Vulnerability
https://notcve.org/view.php?id=CVE-2022-47941
22 Dec 2022 — An issue was discovered in ksmbd in the Linux kernel 5.15 through 5.19 before 5.19.2. fs/ksmbd/smb2pdu.c omits a kfree call in certain smb2_handle_negotiate error conditions, aka a memory leak. This vulnerability allows remote attackers to create a denial-of-service condition on affected installations of Linux Kernel. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of SMB2_NEGOTIATE commands. The issue results from the lack of memory release after i... • http://www.openwall.com/lists/oss-security/2022/12/23/10 • CWE-401: Missing Release of Memory after Effective Lifetime •
