Summary

kernel security update

Details

The Linux Kernel, the operating system core itself.

Security Fix(es):

In binder_vma_close of binder.c, there is a possible use after free due to improper locking. 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)

A 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].”

In 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)

There 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't use current->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->nsproxy leading to invalidly decreasing its reference counter later causing the use-after-free vulnerability. We recommend upgrading to version 5.10.160 or above(CVE-2022-4696)

Severity

7.8 (High)

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
