CVE-2021-46915
In the Linux kernel, the following vulnerability has been resolved: netfilter: nftlimit: avoid possible divide error in nftlimitinit divu64 divides u64 by u32. nftlimitinit wants to divide u64 by u64, use the appropriate math function div64u64 divide error: 0000 1 PREEMPT SMP KASAN CPU: 1 PID: 83...
CVE-2021-46913
In the Linux kernel, the following vulnerability has been resolved: netfilter: nftables: clone set element expression template memcpy breaks when using connlimit in set elements. Use nftexprclone to initialize the connlimit expression list, otherwise connlimit garbage collector crashes when walki...

OESA-2024-1180 kernel security update
The Linux Kernel, the operating system core itself. Security Fixes: Transmit requests in Xen's virtual network protocol can consist of multiple parts. While not really useful, except for the initial part any of them may be of zero length, i.e. carry no data at all. Besides a certain initial porti...
SUSE CVE-2023-52433
In the Linux kernel, the following vulnerability has been resolved: netfilter: nftsetrbtree: skip sync GC for new elements in this transaction New elements in this transaction might expired before such transaction ends. Skip sync GC for such elements otherwise commit path might walk over an alrea...

kernel: inactive elements in nft_pipapo_walk
A use-after-free flaw was found in the Netfilter subsystem in the Linux kernel via the nftpipapowalk function. This issue may allow a local user with CAPNETADMIN capability to trigger an application crash, information disclosure, or local privilege escalation...
PT-2024-7711 · Linux +2 · Linux Kernel +2
Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: The vulnerability is related to a memory leak in the nft flow offload component of the Linux kernel. Specifically, the issue arises when the direct xmit path is used, and the dst relea...

kernel: buffer overflow in nft_set_desc_concat_parse()
A vulnerability was found in the Linux kernel's nftsetdescconcatparse function .This flaw allows an attacker to trigger a buffer overflow via nftsetdescconcatparse , causing a denial of service and possibly to run code...
AZL-62764 CVE-2024-1085 affecting package kernel for versions less than 6.6.35.1-5
A use-after-free vulnerability in the Linux kernel's netfilter: nftables component can be exploited to achieve local privilege escalation. The nftsetelemcatchalldeactivate function checks whether the catch-all set element is active in the current generation instead of the next generation before...
UBUNTU-CVE-2024-1086
A use-after-free vulnerability in the Linux kernel's netfilter: nftables component can be exploited to achieve local privilege escalation. The nftverdictinit function allows positive values as drop error within the hook verdict, and hence the nfhookslow function can cause a double free...
kernel: use after free in nft_immediate_deactivate
A use-after-free flaw was found in the Linux kernel's netfilter: nftables component, which can be exploited to achieve local privilege escalation. On an error when building a nftables rule, deactivating immediate expressions in nftimmediatedeactivate can unbind the chain and objects can be...
kernel: uninitialized registers on stack in nft_do_chain can cause kernel pointer leakage to UM
A flaw was found in the Linux kernel in net/netfilter/nftablescore.c:nftdochain, which can cause a use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker...
AZL-33913 CVE-2024-0607 affecting package kernel for versions less than 5.15.148.1-1
A flaw was found in the Netfilter subsystem in the Linux kernel. The issue is in the nftbyteordereval 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...
