CVE-2023-28466

do_tls_getsockopt in net/tls/tls_main.c in the Linux kernel through 6.2.6 lacks a lock_sock call, leading to a race condition (with a resultant use-after-free or NULL pointer dereference).

do_tls_getsockopt in net/tls/tls_main.c in the Linux kernel through 6.2.6 lacks a lock_sock call, leading to a race condition (with a resultant use-after-free or NULL pointer dereference).

The Linux Kernel, the operating system core itself.

Security Fix(es):

Intel microprocessor generations 6 to 8 are affected by a new Spectre variant that is able to bypass their retpoline mitigation in the kernel to leak arbitrary data. An attacker with unprivileged user access can hijack return instructions to achieve arbitrary speculative code execution under certain microarchitecture-dependent conditions.(CVE-2022-29901)

A flaw was found in the Linux kernel Traffic Control (TC) subsystem. Using a specific networking configuration (redirecting egress packets to ingress using TC action "mirred") a local unprivileged user could trigger a CPU soft lockup (ABBA deadlock) when the transport protocol in use (TCP or SCTP) does a retransmission, resulting in a denial of service condition.(CVE-2022-4269)

A flaw was found in the Linux kernel. A use-after-free may be triggered in asus_kbd_backlight_set when plugging/disconnecting in a malicious USB device, which advertises itself as an Asus device. Similarly to the previous known CVE-2023-25012, but in asus devices, the work_struct may be scheduled by the LED controller while the device is disconnecting, triggering a use-after-free on the struct asus_kbd_leds *led structure. A malicious USB device may exploit the issue to cause memory corruption with controlled data.(CVE-2023-1079)

Kernel: denial of service in tipc_conn_close(CVE-2023-1382)

do_tls_getsockopt in net/tls/tls_main.c in the Linux kernel through 6.2.6 lacks a lock_sock call, leading to a race condition (with a resultant use-after-free or NULL pointer dereference).(CVE-2023-28466)

Use After Free vulnerability in Linux kernel traffic control index filter (tcindex) allows Privilege Escalation. The imperfect hash area can be updated while packets are traversing, which will cause a use-after-free when 'tcf_exts_exec()' is called with the destroyed tcf_ext. A local attacker user can use this vulnerability to elevate its privileges to root. This issue affects Linux Kernel: from 4.14 before git commit ee059170b1f7e94e55fa6cadee544e176a6e59c2.(CVE-2023-1281)

The Linux Kernel, the operating system core itself.

Security Fix(es):

When SMT is enabled, certain AMD processors may speculatively execute instructions using a target from the sibling thread after an SMT mode switch potentially resulting in information disclosure.(CVE-2022-27672)

A flaw was found in the Linux kernel. A use-after-free may be triggered in asus_kbd_backlight_set when plugging/disconnecting in a malicious USB device, which advertises itself as an Asus device.

In the Linux kernel before 5.19, drivers/gpu/drm/arm/malidp_planes.c misinterprets the get_sg_table return value (expects it to be NULL in the error case, whereas it is actually an error pointer).(CVE-2023-23004)

A use-after-free flaw was found in the Linux kernel’s core dump subsystem. This flaw allows a local user to crash the system. Only if patch 390031c94211 ("coredump: Use the vma snapshot in fill_files_note") not applied yet, then kernel could be affected.(CVE-2023-1249)

In the Linux kernel before 6.1.3, fs/ntfs3/inode.c does not validate the attribute name offset. An unhandled page fault may occur.(CVE-2022-48424)

In the Linux kernel before 6.1.3, fs/ntfs3/record.c does not validate resident attribute names. An out-of-bounds write may occur.(CVE-2022-48423)

In the Linux kernel through 6.2.7, fs/ntfs3/inode.c has an invalid kfree because it does not validate MFT flags before replaying logs.(CVE-2022-48425)

Use After Free vulnerability in Linux kernel traffic control index filter (tcindex) allows Privilege Escalation.

This kernel update is based on upstream 5.15.106 and fixes atleast the following security issues:

A flaw was found in the Linux Kernel. The tun/tap sockets have their socket UID hardcoded to 0 due to a type confusion in their initialization function. While it will be often correct, as tuntap devices require CAP_NET_ADMIN, it may not always be the case, e.g., a non-root user only having that capability. This would make tun/tap sockets being incorrectly treated in filtering/routing decisions, possibly bypassing network filters (CVE-2023-1076).

In the Linux kernel, pick_next_rt_entity() may return a type confused entry, not detected by the BUG_ON condition, as the confused entry will not be NULL, but list_head.The buggy error condition would lead to a type confused entry with the list head,which would then be used as a type confused sched_rt_entity,causing memory corruption (CVE-2023-1077).

A flaw was found in the Linux kernel. A use-after-free may be triggered in asus_kbd_backlight_set when plugging/disconnecting in a malicious USB device, which advertises itself as an Asus device. Similarly to the previous known CVE-2023-25012, but in asus devices, the work_struct may be scheduled by the LED controller while the device is disconnecting, triggering a use-after-free on the struct asus_kbd_leds *led structure. A malicious USB device may exploit the issue to cause memory corruption with controlled data (CVE-2023-1079).

A flaw use after free in the Linux kernel integrated infrared receiver/ transceiver driver was found in the way user detaching rc device. A local user could use this flaw to crash the system or potentially escalate their privileges on the system (CVE-2023-1118).

A use-after-free flaw was found in btrfs_search_slot in fs/btrfs/ctree.c in btrfs in the Linux Kernel.This flaw allows an attacker to crash the system and possibly cause a kernel information leak (CVE-2023-1611).

A flaw use after free in the Linux kernel Xircom 16-bit PCMCIA (PC-card) Ethernet driver was found.A local user could use this flaw to crash the system or potentially escalate their privileges on the system (CVE-2023-1670).

A use-after-free vulnerability in the Linux Kernel traffic control index filter (tcindex) can be exploited to achieve local privilege escalation. The tcindex_delete function which does not properly deactivate filters in case of a perfect hashes while deleting the underlying structure which can later lead to double freeing the structure. A local attacker user can use this vulnerability to elevate its privileges to root (CVE-2023-1829).

A use-after-free flaw was found in xgene_hwmon_remove in drivers/hwmon/ xgene-hwmon.c in the Hardware Monitoring Linux Kernel Driver (xgene-hwmon). This flaw could allow a local attacker to crash the system due to a race problem. This vulnerability could even lead to a kernel information leak problem (CVE-2023-1855).

A use-after-free flaw was found in btsdio_remove in drivers\bluetooth
btsdio.c in the Linux Kernel. In this flaw, a call to btsdio_remove with an unfinished job, may cause a race problem leading to a UAF on hdev devices (CVE-2023-1989).

A use-after-free flaw was found in ndlc_remove in drivers/nfc/st-nci/ndlc.c in the Linux Kernel. This flaw could allow an attacker to crash the system due to a race problem (CVE-2023-1990).

A flaw was found in the Linux kernel Traffic Control (TC) subsystem. Using a specific networking configuration (redirecting egress packets to ingress using TC action "mirred") a local unprivileged user could trigger a CPU soft lockup (ABBA deadlock) when the transport protocol in use (TCP or SCTP) does a retransmission, resulting in a denial of service condition (CVE-2022-4269).

A use-after-free vulnerability was found in __nfs42_ssc_open() in fs/nfs/nfs4file.c in the Linux kernel. This flaw allows an attacker to conduct a remote denial of service (CVE-2022-4379).

The Linux kernel through 6.1.9 has a Use-After-Free in bigben_remove in…
