CVSS v3.1 |
| A flaw was found in GLib. A state confusion issue exists in g_dbus_node_info_new_for_xml() in the gio/gdbusintrospection.c file when processing malformed D-Bus introspection XML, specifically with a `node` element nested within other elements like `method`, `signal`, `property` or `arg`. This issue can cause an unsigned integer overflow and lead to an out-of-bounds read, resulting in a denial of service. |
| A flaw was found in GLib. An out-of-bounds read of only 2 bytes can occur in the g_date_time_get_ymd function in the glib/gdatetime.c file when an invalid GDateTime object produced by the g_date_time_add_full function is processed. This flaw can corrupt the date output and potentially cause logic errors that may lead to a denial of service. |
| A flaw was found in GLib. An off-by-one error can occur in the gvs_tuple_is_normal function in the glib/gvariant-serialiser.c file when doing an alignment padding check because the bounds check uses > instead of >=, causing an out-of-bounds read of only 1 byte. This issue can cause a minor information disclosure of 1 byte and a denial of service when the out-of-bounds read crosses a page boundary. |
| A flaw was found in GLib (Gnome Lib). This vulnerability allows a remote attacker to cause heap corruption, leading to a denial of service or potential code execution via a buffer-underflow in the GVariant parser when processing maliciously crafted input strings. |
| In acquireMemory of bt_bqr_offload.cc, there is a possible way to trigger an out of bounds write via a buffer size underflow due to an incorrect bounds check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. |
| In multiple locations, there is a possible way to trigger an out of bounds write in the shared memory tracking bitmap due to a missing bounds check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. |
| In slice_header of hevc_decoder, there is a possible Non-Heap Buffer Overflow due to a buffer overflow. This could lead to local escalation of privilege with execution privileges needed. User interaction is for exploitation. |
| In knee_function_info of hevc_decoder, there is a possible Non-Heap Buffer Overflow due to a buffer overflow. This could lead to local escalation of privilege with execution privileges needed. User interaction is for exploitation. |
| In StNfc_hal_write of hal_st21nfc.cc, there is a possible way to trigger an out of bounds write into global memory due to an incorrect bounds check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. |
| In multiple functions of face_status.h, there is a possible way to modify verified biometric enrollment data in shared memory due to a race condition. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. |
| In sub_layer_hrd_parameters of hevc_decoder, there is a possible Non-Heap Buffer Overflow due to a buffer overflow. This could lead to local escalation of privilege with execution privileges needed. User interaction is for exploitation. |
| In userdata_report of hwcodec_firmware, there is a possible Logic error due to a logic error in the code. This could lead to local information disclosure with execution privileges needed. User interaction is for exploitation. |
| In has_booted_successfully of sys_state_setup_otp_ta.c, there is a possible way to trigger a permanent denial of service via premature anti-rollback fuse updates due to a logic error. This could lead to local denial of service with no additional execution privileges needed. User interaction is not needed for exploitation. |
| In cpb_cnt of avc_decoder, there is a possible Non-Heap Buffer Overflow due to a buffer overflow. This could lead to local escalation of privilege with execution privileges needed. User interaction is for exploitation. |
| In s_inter_rps_pred of hevc_decoder, there is a possible Non-Heap Buffer Overflow due to a buffer overflow. This could lead to local escalation of privilege with execution privileges needed. User interaction is for exploitation. |
| In check_constraint_monotonicity of lib.rs, there is a possible way to downgrade stored security policies and bypass rollback protection due to a logic error. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. |
| In s_copy_host_apb_param of multiple files, there is a possible way to trigger an out of bounds read in the video decoder command queue due to a logic error. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation. |
| In SendInfo of UssiController.cpp, there is a possible way to corrupt memory via a dangling connection listener pointer due to a use after free. This could lead to remote escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. |
| In the Linux kernel, the following vulnerability has been resolved:
inet: reject unhashed sockets during established lookups
TCP established ehash lookups are lockless. The socket caches involved
use SLAB_TYPESAFE_BY_RCU, so memory can be reused before an RCU reader
that retained its old address has finished.
After a tuple match, __inet_lookup_established() and
__inet6_lookup_established() acquire a reference and repeat the tuple
check. They do not check whether the new object is hashed. If the
address is reused for a socket with the same tuple, the lookup can
acquire a reference to the new object and return it while its nulls node
is unhashed.
A PoC that drives reuse with a SYN cookie request socket reproduced the
crash. The new request socket is unhashed and has a NULL rsk_listener.
A lookup that had loaded the address of the old request socket acquired
the reference published by tcp_get_cookie_sock() and returned the new
object. tcp_v4_rcv() then read sk_state through the NULL listener.
The resulting crash was:

Kernel panic - not syncing: Fatal exception in interrupt
After taking a reference, check whether the nulls node is unhashed in
both IPv4 and IPv6 established lookups. If it is unhashed or the tuple
no longer matches, drop the reference and restart the lookup.
Lookups racing with the TIME_WAIT hashdance, or with a request being
replaced by its child, now restart and find the new socket instead of
returning the old one.
Request sockets that were never inserted into ehash can have a nonzero
refcount, and a stale lookup can hold a transient reference. Therefore,
when SYN cookie, Fast Open, and request migration paths fail after
setting a nonzero refcount, release the references held by those paths
with reqsk_put() instead of freeing the request directly. |
| In GetTwiddledMiptreeSparsePageMap of texmgmt.c, there is a possible way to trigger an out of bounds write due to a logic error. This could lead to remote code execution with no additional execution privileges needed. User interaction is not needed for exploitation. |
