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

Security Fix(es):

* kernel: use after free in unix_stream_sendpage (CVE-2023-4622) * kernel: vmwgfx: reference count issue leads to use-after-free in surface handling (CVE-2023-5633) * kernel: netfilter: potential slab-out-of-bound access due to integer underflow (CVE-2023-42753) * Kernel: UAF during login when accessing the shost ipaddress (CVE-2023-2162) * hw amd: Return Address Predictor vulnerability leading to information disclosure (CVE-2023-20569)

OESA-2023-1293 — kernel security update

Affected: openEuler:20.03-LTS-SP1: kernel, openEuler:20.03-LTS-SP3: kernel, openEuler:22.03-LTS: kernel, openEuler:22.03-LTS-SP1: kernel

The Linux Kernel, the operating system core itself. Security Fix(es): A use-after-free vulnerability was found in iscsi_sw_tcp_session_create in drivers/scsi/iscsi_tcp.c in SCSI sub-component in the Linux Kernel. In this flaw an attacker could leak kernel internal information.(CVE-2023-2162) An out-of-bounds memory access flaw was found in the Linux kernel’s XFS file system in how a user restores an XFS image after failure (with a dirty log journal). This flaw allows a local user to crash or potentially escalate their privileges on the system(CVE-2023-2124) 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-2023-32233)
