An issue was discovered in the Linux kernel before 6.3.8. fs/smb/server/connection.c in ksmbd does not validate the relationship between the NetBIOS header's length field and the SMB header sizes, via pdu_size in ksmbd_conn_handler_loop, leading to an out-of-bounds read. • https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.3.8 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/fs/smb/server?id=368ba06881c395f1c9a7ba22203cf8d78b4addc0 https://security.netapp.com/advisory/ntap-20230824-0011 • CWE-125: Out-of-bounds Read •

CVE-2023-2975 – AES-SIV implementation ignores empty associated data entries
https://notcve.org/view.php?id=CVE-2023-2975
Issue summary: The AES-SIV cipher implementation contains a bug that causes it to ignore empty associated data entries which are unauthenticated as a consequence. Impact summary: Applications that use the AES-SIV algorithm and want to authenticate empty data entries as associated data can be mislead by removing adding or reordering such empty entries as these are ignored by the OpenSSL implementation. We are currently unaware of any such applications. The AES-SIV algorithm allows for authentication of multiple associated data entries along with the encryption. To authenticate empty data the application has to call EVP_EncryptUpdate() (or EVP_CipherUpdate()) with NULL pointer as the output buffer and 0 as the input buffer length. The AES-SIV implementation in OpenSSL just returns success for such a call instead of performing the associated data authentication operation. The empty data thus will not be authenticated. As this issue does not affect non-empty associated data authentication and we expect it to be rare for an application to use empty associated data entries this is qualified as Low severity issue.

CVE-2023-3141 – kernel: Use after free bug in r592_remove
https://notcve.org/view.php?id=CVE-2023-3141
A use-after-free flaw was found in r592_remove in drivers/memstick/host/r592.c in media access in the Linux Kernel. This flaw allows a local attacker to crash the system at device disconnect, possibly leading to a kernel information leak.

CVE-2023-2598
https://notcve.org/view.php?id=CVE-2023-2598
A flaw was found in the fixed buffer registration code for io_uring (io_sqe_buffer_register in io_uring/rsrc.c) in the Linux kernel that allows out-of-bounds access to physical memory beyond the end of the buffer. This flaw enables full local privilege escalation. Se encontró una falla en el código de registro de búfer fijo para io_uring (io_sqe_buffer_register en io_uring/rsrc.c) en el kernel de Linux que permite el acceso fuera de los límites a la memoria física más allá del final del búfer. Esta falla permite la escalada completa de privilegios locales. • https://github.com/ysanatomic/io_uring_LPE-CVE-2023-2598 https://github.com/cainiao159357/CVE-2023-2598 http://www.openwall.com/lists/oss-security/2024/04/24/3 https://security.netapp.com/advisory/ntap-20230703-0006 https://www.openwall.com/lists/oss-security/2023/05/08/3 • CWE-416: Use After Free CWE-787: Out-of-bounds Write •
