Summary
It was discovered that the Layer 2 Tunneling Protocol (L2TP) implementation
in the Linux kernel contained a race condition when releasing PPPoL2TP
sockets in certain conditions, leading to a use-after-free vulnerability. A
local attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2022-20567)
It was discovered that the ext4 file system implementation in the Linux
kernel did not properly handle block device modification while it is
mounted. A privileged attacker could use this to cause a denial of service
(system crash) or possibly expose sensitive information. (CVE-2023-34256)
Eric Dumazet discovered that the netfilter subsystem in the Linux kernel
did not properly handle DCCP conntrack buffers in certain situations,
leading to an out-of-bounds read vulnerability. An attacker could possibly
use this to expose sensitive information (kernel memory). (CVE-2023-39197)
It was discovered that a race condition existed in the AppleTalk networking
subsystem of the Linux kernel, leading to a use-after-free vulnerability. A
local attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2023-51781)
It was discovered that the ext4 file system implementation in the Linux
kernel did not properly handle the remount operation in certain cases,
leading to a use-after-free vulnerability. A local attacker could use this
to cause a denial of service (system crash) or possibly expose sensitive
information. (CVE-2024-0775)
Notselwyn discovered that the netfilter subsystem in the Linux kernel did
not properly handle verdict parameters in certain cases, leading to a use-
after-free vulnerability. A local attacker could use this to cause a denial
of service (system crash) or possibly execute arbitrary code.
(CVE-2024-1086)
It was discovered that a race condition existed in the SCSI Emulex
LightPulse Fibre Channel driver in the Linux kernel when unregistering FCF
and re-scanning an HBA FCF table, leading to a null pointer dereference
vulnerability. A local attacker could use this to cause a denial of service
(system crash). (CVE-2024-24855)

Use-after-free in Linux kernel's netfilter: nf_tables component
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. The nft_verdict_init() function allows positive values as drop error within the hook verdict, and hence the nf_hook_slo…

Kernel: use-after-free while changing the mount option in __ext4_remount leading
A use-after-free flaw was found in the __ext4_remount in fs/ext4/super.c in ext4 in the Linux kernel. This flaw allows a local user to cause an information leak problem while freeing the old quota file names before a potential failure, leading to a use-after-…

Medium 5.0
Race condition vulnerability in Linux kernel scsi device driver lpfc_unregister_fcf_rescan()
A race condition was found in the Linux kernel's scsi device driver in lpfc_unregister_fcf_rescan() function. This can result in a null pointer dereference issue, possibly leading to a kernel panic or denial of service issue.

Medium 4.0
Kernel: dccp: conntrack out-of-bounds read in nf_conntrack_dccp_packet()
An out-of-bounds read vulnerability was found in Netfilter Connection Tracking (conntrack) in the Linux kernel. This flaw allows a remote user to disclose sensitive information via the DCCP protocol.
