CVE-2023-3390

A use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in net/netfilter/nf_tables_api.c.

Mishandled error handling with NFT_MSG_NEWRULE makes it possible to use a dangling pointer in the same transaction causing a use-after-free vulnerability. This flaw allows a local attacker with user access to cause a privilege escalation issue.

We recommend upgrading past commit 1240eb93f0616b21c675416516ff3d74798fdc97.

Security Fix(es):

An issue was discovered in the Linux kernel through 6.0.9. drivers/media/dvb-core/dvb_net.c has a .disconnect versus dvb_device_open race condition that leads to a use-after-free.(CVE-2022-45886)

It was discovered that the IP-VLAN network driver for the Linux kernel did not properly initialize memory in some situations, leading to an out-of- bounds write vulnerability. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.(CVE-2023-3090)

Querijn Voet discovered that a race condition existed in the io_uring subsystem in 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-2023-3389)

It was discovered that the netfilter subsystem in the Linux kernel did not properly handle some error 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-2023-3390)

Mingi Cho discovered that the netfilter subsystem in the Linux kernel did not properly validate the status of a nft chain while performing a lookup by id, leading to a use-after-free vulnerability. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.(CVE-2023-31248)

Shir Tamari and Sagi Tzadik discovered that the OverlayFS implementation in the Ubuntu Linux kernel did not properly perform permission checks in certain situations. A local attacker could possibly use this to gain elevated privileges.(CVE-2023-32629)

Tanguy Dubroca discovered that the netfilter subsystem in the Linux kernel did not properly handle certain pointer data type, leading to an out-of- bounds write vulnerability. A privileged attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.(CVE-2023-35001)

Hangyu Hua discovered that the Flower classifier implementation in the Linux kernel contained an out-of-bounds write vulnerability. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.(CVE-2023-35788)

This kernel update is based on upstream 5.15.120 and fixes atleast the following security issues:

A flaw null pointer dereference in the Linux kernel DECnet networking protocol was found. A remote user could use this flaw to crash the system. This is fixed by removing DECnet support (CVE-2023-3338).

A use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in net/netfilter/nf_tables_api.c. Mishandled error handling with NFT_MSG_NEWRULE makes it possible to use a dangling pointer in the same transaction causing a use-after-free vulnerability. This flaw allows a local attacker with user access to cause a privilege escalation issue (CVE-2023-3390).

Linux Kernel nftables Use-After-Free Local Privilege Escalation Vulnerability; nft_chain_lookup_byid() failed to check whether a chain was active and CAP_NET_ADMIN is in any user or network namespace (CVE-2023-31248).

Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability; nft_byteorder poorly handled vm register contents when CAP_NET_ADMIN is in any user or network namespace (CVE-2023-35001).

NOTE!! This kernel also contains a fix for dkms builds hanging / stalling during upgrade to Mageia 9 (mga#31982) due to the new make 4.4 series utility ending up in a loop processing Makefile in kernel-devel packages. So if you use dkms packaged drivers, you need to be running this kernel (or any later released ones) before you do an online upgrade to avoid the upgrade stalling / hanging.

For other upstream fixes in this update, see the referenced changelogs.

This kernel-linus update is based on upstream 5.15.120 and fixes atleast the following security issues:
