LSN-0110-1: Kernel Live Patch Security Notice

In the Linux kernel, the following vulnerability has been resolved: tty: ngsm: require CAPNETADMIN to attach NGSM0710 ldisc Any unprivileged user can attach NGSM0710 ldisc, but it requires CAPNETADMIN to create a GSM network anyway. Require initial namespace CAPNETADMIN to do that.CVE-2023-52880 ...

Linux Distros Unpatched Vulnerability : CVE-2023-3773

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - A flaw was found in the Linux kernel's IP framework for transforming packets XFRM subsystem. This issue may allow a malicious user with CAPNETADMIN privileges t...

Linux Distros Unpatched Vulnerability : CVE-2011-1080

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - The doreplace function in net/bridge/netfilter/ebtables.c in the Linux kernel before 2.6.39 does not ensure that a certain name field ends with a '\0' character...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: firmwareloader: Block path traversal Most firmware names are hardcoded strings, or are constructed from fairly constrained format strings where the dynamic parts are just some hexadecimal numbers or similar elements. However,...

kernel: tty: n_gsm: require CAP_NET_ADMIN to attach N_GSM0710 ldisc

In the Linux kernel, the following vulnerability has been resolved: tty: ngsm: require CAPNETADMIN to attach NGSM0710 ldisc Any unprivileged user can attach NGSM0710 ldisc, but it requires CAPNETADMIN to create a GSM network anyway. Require initial namespace CAPNETADMIN to do that...

kernel: netfilter: use-after-free in nft_trans_gc_catchall_sync leads to privilege escalation

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 NFTCHAIN object or NFTOBJECT object, allowing a local...

SUSE CVE-2023-3772

A flaw was found in the Linux kernel's IP framework for transforming packets XFRM subsystem. This issue may allow a malicious user with CAPNETADMIN privileges to directly dereference a NULL pointer in xfrmupdateaeparams, leading to a possible kernel crash and denial of service...

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...

kernel: null pointer dereference vulnerability in nft_dynset_init()

A null pointer dereference vulnerability was found in nftdynsetinit in net/netfilter/nftdynset.c in nftables in the Linux kernel. This issue may allow a local attacker with CAPNETADMIN user privilege to trigger a denial of service...

kernel: ipv4: NULL pointer dereference in ipv4_send_dest_unreach()

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 ipoptionscompile, which is not always the case if the skb is re-routed by ipvs. This issue may allow a local user with CAPNETADMIN privileges t...

kernel: null pointer dereference vulnerability in nft_dynset_init()

A null pointer dereference vulnerability was found in nftdynsetinit in net/netfilter/nftdynset.c in nftables in the Linux kernel. This issue may allow a local attacker with CAPNETADMIN user privilege to trigger a denial of service...

kernel: nf_tables: stack-out-of-bounds-read in nft_byteorder_eval()

An out-of-bounds OOB memory access flaw was found in the Netfilter module in the Linux kernel's nftbyteordereval in net/netfilter/nftbyteorder.c. A bound check failure allows a local attacker with CAPNETADMIN access to cause a local privilege escalation issue due to incorrect data alignment...

kernel: UAF in nftables when nft_set_lookup_global triggered after handling named and anonymous sets in batch requests

A use-after-free flaw was found in the Netfilter subsystem of the Linux kernel when processing named and anonymous sets in batch requests, which can lead to performing arbitrary reads and writes in kernel memory. This flaw allows a local user with CAPNETADMIN capability to crash or potentially...
