kernel-3.10.0-1160.102.1.el7

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

* kernel: net/sched: cls_u32 component reference counter leak if tcf_change_indev() fails (CVE-2023-3609)
* kernel: netfilter: use-after-free in nf_tables when processing batch requests can lead to privilege escalation (CVE-2023-32233)
* kernel: nf_tables: stack-out-of-bounds-read in nft_byteorder_eval() (CVE-2023-35001)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Bug Fix(es):

* Low memory deadlock with md devices and external (imsm) metadata handling (BZ#1703180)
* cifs: memory leak in smb2_query_symlink (BZ#2166706)
* bnxt_en: panic in bnxt_tx_int Redux (BZ#2175062)
* NFS client loop in BIND_CONN_TO_SESSION (BZ#2219604)

CVE-2023-32233
In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users can obtain root privileges. This occurs because anonymous sets are mishandled.
CVE-2023-35001
Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability; nft_byteorder poorly handled vm register contents when CAP_NET_ADMIN is in any user or network namespace
CVE-2023-3609
A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited to achieve local privilege escalation. If tcf_change_indev() fails, u32_set_parms() will immediately return an error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can control the reference counter and set it to zero, they can cause the reference to be freed, leading to a use-after-free vulnerability. We recommend upgrading past commit 04c55383fa5689357bcdd2c8036725a55ed632bc.
