<Note Title="Summary" Type="General" Ordinal="2" xml:lang="en">An update for kernel is now available for openEuler-20.03-LTS-SP1.</Note>
<Note Title="Description" Type="General" Ordinal="3" xml:lang="en">The Linux Kernel, the operating system core itself.
Security Fix(es):
In multiple functions of binder.c, there is a possible memory corruption due to a use after free. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
(CVE-2023-21255)
A use-after-free vulnerability in the Linux kernel&apos;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.
(CVE-2023-3609)
An out-of-bounds write vulnerability in the Linux kernel&apos;s net/sched: sch_qfq component can be exploited to achieve local privilege escalation.
The qfq_change_agg() function in net/sched/sch_qfq.c allows an out-of-bounds write because lmax is updated according to packet sizes without bounds checks.
We recommend upgrading past commit 3e337087c3b5805fe0b8a46ba622a962880b5d64.
(CVE-2023-3611)
A use-after-free vulnerability in the Linux kernel&apos;s net/sched: cls_fw component can be exploited to achieve local privilege escalation.

We recommend upgrading past commit 0323bce598eea038714f941ce2b22541c46d488f.
(CVE-2023-3776)
An out-of-bounds memory access flaw was found in the Linux kernels TUN/TAP device driver functionality in how a user generates a malicious (too big) networking packet when napi frags is enabled. This flaw allows a local user to crash or potentially escalate their privileges on the system.(CVE-2023-3812)</Note>
