This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-254837884References: Upstream kernel(CVE-2023-20928)\r\n\r\nA heap overflow bug in ksmbd_decode_ntlmssp_auth_blob in which nt_len can be less than CIFS_ENCPWD_SIZE. This results in a negative blen argument for ksmbd_auth_ntlmv2, where it calls memcpy using blen on memory allocated by kmalloc(blen + CIFS_CRYPTO_KEY_SIZE). Note that CIFS_ENCPWD_SIZE is 16 and CIFS_CRYPTO_KEY_SIZE is 8. We believe this bug can only result in a remote DOS and not privilege escalation nor RCE, as the heap overflow occurs when blen is in range (-8, -1].”\r\n\r\nReference:\nhttps://securityonline.info/cve-2023-0210-flaw-in-linux-kernel-allows-unauthenticated-remote-dos-attacks/\nhttps://www.spinics.net/lists/stable-commits/msg282893.html(CVE-2023-0210)\r\n\r\nIn rndis_query_oid in drivers/net/wireless/rndis_wlan.c in the Linux kernel through 6.1.5, there is an integer overflow in an addition.(CVE-2023-23559)\r\n\r\nThere exists a use-after-free vulnerability in the Linux kernel through io_uring and the IORING_OP_SPLICE operation. If IORING_OP_SPLICE is missing the IO_WQ_WORK_FILES flag, which signals that the operation won\u0026apos;t use current-\u0026gt;nsproxy, so its reference counter is not increased. This assumption is not always true as calling io_splice on specific files will call the get_uts function which will use current-\u0026gt;nsproxy leading to invalidly decreasing its reference counter later causing the use-after-free vulnerability.
