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. 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)

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 (&quot;coredump: Use the vma snapshot in fill_files_note&quot;) not applied yet, then kernel could be affected.(CVE-2023-1249)


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)

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. The imperfect hash area can be updated while packets are traversing, which will cause a use-after-free when &apos;tcf_exts_exec()&apos; 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)

In the Linux kernel before 5.16.3, drivers/usb/dwc3/dwc3-qcom.c misinterprets the dwc3_qcom_create_urs_usb_platdev return value (expects it to be NULL in the error case, whereas it is actually an error pointer).(CVE-2023-22999)</Note>

			<Note Title="Vulnerability Description" Type="General" Ordinal="10" xml:lang="en">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.</Note>
