OESA-2023-1188

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 asuskbdbacklightset 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 workstruct may be scheduled by the LED controller while the device is disconnecting, triggering a use-after-free on the struct asuskbdleds *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/malidpplanes.c misinterprets the getsg_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 fillfilesnote") not applied yet, then kernel could be affected.(CVE-2023-1249)

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

dotlsgetsockopt in net/tls/tlsmain.c in the Linux kernel through 6.2.6 lacks a locksock 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 'tcfextsexec()' 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 dwc3qcomcreateursusb_platdev return value (expects it to be NULL in the error case, whereas it is actually an error pointer).(CVE-2023-22999)
