Summary
kernel security update
Details

The Linux Kernel, the operating system core itself.

Security Fix(es):

openeuler-linux-kernel-4.19.0-cbs_destroy-NULL-ptr-deref-391216(CVE-2021-33630)

openeuler-linux-kernel-5.10.149-ext4_write_inline_data-kernel_bug-365020(CVE-2021-33631)

An issue was discovered in the Linux kernel through 6.3.8. A use-after-free was found in ravb_remove in drivers/net/ethernet/renesas/ravb_main.c.(CVE-2023-35827)

An out-of-bounds read vulnerability was found in the NVMe-oF/TCP subsystem in the Linux kernel. This issue may allow a remote attacker to send a crafted TCP packet, triggering a heap-based buffer overflow that results in kmalloc data being printed and potentially leaked to the kernel ring buffer (dmesg).(CVE-2023-6121)

A heap out-of-bounds write vulnerability in the Linux kernel's Performance Events system component can be exploited to achieve local privilege escalation.

A perf_event's read_size can overflow, leading to an heap out-of-bounds increment or write in perf_read_group().

We recommend upgrading past commit 382c27f4ed28f803b1f1473ac2d8db0afc795a1b.
