CVE-2023-2513

A use-after-free vulnerability was found in the Linux kernel's ext4 filesystem in the way it handled the extra inode size for extended attributes. This flaw could allow a privileged local user to cause a system crash or other undefined behaviors.

The Linux Kernel, the operating system core itself.

Security Fix(es):

A vulnerability was found in the HCI sockets implementation due to a missing capability check in net/bluetooth/hci_sock.c in the Linux Kernel. This flaw allows an attacker to unauthorized execution of management commands, compromising the confidentiality, integrity, and availability of Bluetooth communication.(CVE-2023-2002)

A speculative pointer dereference problem exists in the Linux Kernel on the do_prlimit() function. The resource argument value is controlled and is used in pointer arithmetic for the 'rlim' variable and can be used to leak the contents. We recommend upgrading past version 6.1.8 or commit 739790605705ddcf18f21782b9c99ad7d53a8c11(CVE-2023-0458)

In emac_probe, &adpt->work_thread is bound with emac_work_thread. Then it will be started by timeout handler emac_tx_timeout or a IRQ handler emac_isr. If we remove the driver which will call emac_remove to make cleanup, there may be a unfinished work. This could lead to a use-after-free.

Upstream fix: https://github.com/torvalds/linux/commit/6b6bc5b8bd2d(CVE-2023-2483)

An issue was discovered in the Linux kernel before 6.1.11. In net/netrom/af_netrom.c, there is a use-after-free because accept is also allowed for a successfully connected AF_NETROM socket. However, in order for an attacker to exploit this, the system must have netrom routing configured or the attacker must have the CAP_NET_ADMIN capability.(CVE-2023-32269)

In the Linux kernel 6.0.8, there is a use-after-free in run_unpack in fs/ntfs3/run.c, related to a difference between NTFS sector size and media sector size.(CVE-2023-26544)

No description is available for this CVE(CVE-2023-0459)

A null pointer dereference issue was found in the sctp network protocol in net/sctp/stream_sched.c in Linux Kernel. If stream_in allocation is failed, stream_out is freed which would further be accessed. A local user could use this flaw to crash the system or potentially cause a denial of service.(CVE-2023-2177)

Jordy Zomer and Alexandra Sandulescu discovered that syscalls invoking the do_prlimit() function in the Linux kernel did not properly handle speculative execution barriers. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2023-0458)

It was discovered that a race condition existed in the btrfs file system implementation 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 expose sensitive information. (CVE-2023-1611)

It was discovered that the XFS file system implementation in the Linux kernel did not properly perform metadata validation when mounting certain images. An attacker could use this to specially craft a file system image that, when mounted, could cause a denial of service (system crash). (CVE-2023-2124)

It was discovered that a use-after-free vulnerability existed in the iSCSI TCP implementation in the Linux kernel. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2023-2162)

It was discovered that the ext4 file system implementation in the Linux kernel did not properly handle extra inode size for extended attributes, leading to a use-after-free vulnerability. A privileged attacker could possibly use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-2513)

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)

It was discovered that the Ricoh R5C592 MemoryStick card reader driver in the Linux kernel contained a race condition during module unload, 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-2023-3141)

It was discovered that a use-after-free vulnerability existed in the IEEE 1394 (Firewire) implementation in the Linux kernel. A privileged attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-3159)

Sanan Hasanov discovered that the framebuffer console driver in the Linux kernel did not properly perform checks for font dimension limits. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-3161)

It was discovered that the kernel->user space relay implementation in the Linux kernel did not properly perform certain buffer calculations, leading to an out-of-bounds read vulnerability. A local attacker could use this to cause a denial of service (system crash) or expose sensitive information (kernel memory). (CVE-2023-3268)

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)

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)
