Summary
A use-after-free flaw was found in the netfilter subsystem of the Linux kernel. If the catchall element is garbage-collected when the pipapo set is removed, the element can be deactivated twice. This can cause a use-after-free issue on an NFT_CHAIN object or NFT_OBJECT object, allowing a local unprivileged user with CAP_NET_ADMIN capability to escalate their privileges on the system.
Severity ?
7.8 (High)

CVE-2023-5717 (GCVE-0-2023-5717)
Vulnerability from cvelistv5 – Published: 2023-10-25 12:55 – Updated: 2025-02-13 17:25

EPSS
Summary
A heap out-of-bounds write vulnerability in the Linux kernel's Linux Kernel Performance Events (perf) component can be exploited to achieve local privilege escalation.
If perf_read_group() is called while an event's sibling_list is smaller than its child's sibling_list, it can increment or write to memory locations outside of the allocated buffer.
We recommend upgrading past commit 32671e3799ca2e4590773fd0e63aaa4229e50c06.

CVE-2024-0607 (GCVE-0-2024-0607)
Vulnerability from cvelistv5 – Published: 2024-01-18 15:41 – Updated: 2025-11-20 18:09

EPSS
Summary
A flaw was found in the Netfilter subsystem in the Linux kernel. The issue is in the nft_byteorder_eval() function, where the code iterates through a loop and writes to the `dst` array. On each iteration, 8 bytes are written, but `dst` is an array of u32, so each element only has space for 4 bytes. That means every iteration overwrites part of the previous element corrupting this array of u32. This flaw allows a local user to cause a denial of service or potentially break NetFilter functionality.

Summary
A NULL pointer dereference flaw was found in the Linux kernel ipv4 stack. The socket buffer (skb) was assumed to be associated with a device before calling __ip_options_compile, which is not always the case if the skb is re-routed by ipvs. This issue may allow a local user with CAP_NET_ADMIN privileges to crash the system.

CVE-2023-46813 (GCVE-0-2023-46813)
Vulnerability from cvelistv5 – Published: 2023-10-27 00:00 – Updated: 2024-08-02 20:53

EPSS
Summary
An issue was discovered in the Linux kernel before 6.5.9, exploitable by local users with userspace access to MMIO registers. Incorrect access checking in the #VC handler and instruction emulation of the SEV-ES emulation of MMIO accesses could lead to arbitrary write access to kernel memory (and thus privilege escalation). This depends on a race condition through which userspace can replace an instruction before the #VC handler reads it.
Severity ?
No CVSS data available.

Summary
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).
Severity ?

CVE-2023-34324 (GCVE-0-2023-34324)
Vulnerability from cvelistv5 – Published: 2024-01-05 16:30 – Updated: 2025-11-04 19:16
VLAI?
EPSS
Summary
Closing of an event channel in the Linux kernel can result in a deadlock.
This happens when the close is being performed in parallel to an unrelated
Xen console action and the handling of a Xen console interrupt in an
unprivileged guest.
The closing of an event channel is e.g. triggered by removal of a
paravirtual device on the other side. As this action will cause console
messages to be issued on the other side quite often, the chance of
triggering the deadlock is not neglectable.
Note that 32-bit Arm-guests are not affected, as the 32-bit Linux kernel
on Arm doesn't use queued-RW-locks, which are required to trigger the
issue (on Arm32 a waiting writer doesn't block further readers to get
the lock).
Severity ?
4.9 (Medium)

Summary
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.

Summary
A flaw was found in the Netfilter subsystem in the Linux kernel. The xt_u32 module did not validate the fields in the xt_u32 structure. This flaw allows a local privileged attacker to trigger an out-of-bounds read by setting the size fields with a value beyond the array boundaries, leading to a crash or information disclosure.
Severity ?

CVE-2023-6817 (GCVE-0-2023-6817)
Vulnerability from cvelistv5 – Published: 2023-12-18 14:37 – Updated: 2025-02-13 17:26
VLAI?
EPSS
Summary
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation.
The function nft_pipapo_walk did not skip inactive elements during set walk which could lead double deactivations of PIPAPO (Pile Packet Policies) elements, leading to use-after-free.
We recommend upgrading past commit 317eb9685095678f2c9f5a8189de698c5354316a.
Severity ?
7.8 (High)

EPSS
Summary
A use-after-free vulnerability in the Linux kernel's ipv4: igmp component can be exploited to achieve local privilege escalation.
A race condition can be exploited to cause a timer be mistakenly registered on a RCU read locked object which is freed by another thread.
We recommend upgrading past commit e2b706c691905fe78468c361aaabc719d0a496f1.
