CVSS v3.1 |
| A logic issue was addressed with improved checks. This issue is fixed in macOS Big Sur 11.6.8, macOS Monterey 12.5, Security Update 2022-005 Catalina. An archive may be able to bypass Gatekeeper. |
| In the Linux kernel, the following vulnerability has been resolved:
x86/fred: Clear WFE in missing-ENDBRANCH #CPs
An indirect branch instruction sets the CPU indirect branch tracker
(IBT) into WAIT_FOR_ENDBRANCH (WFE) state and WFE stays asserted
across the instruction boundary. When the decoder finds an
inappropriate instruction while WFE is set ENDBR, the CPU raises a #CP
fault.
For the "kernel IBT no ENDBR" selftest where #CPs are deliberately
triggered, the WFE state of the interrupted context needs to be
cleared to let execution continue. Otherwise when the CPU resumes
from the instruction that just caused the previous #CP, another
missing-ENDBRANCH #CP is raised and the CPU enters a dead loop.
This is not a problem with IDT because it doesn't preserve WFE and
IRET doesn't set WFE. But FRED provides space on the entry stack
(in an expanded CS area) to save and restore the WFE state, thus the
WFE state is no longer clobbered, so software must clear it.
Clear WFE to avoid dead looping in ibt_clear_fred_wfe() and the
!ibt_fatal code path when execution is allowed to continue.
Clobbering WFE in any other circumstance is a security-relevant bug.

| In the Linux kernel, the following vulnerability has been resolved:
drm/fbdev-dma: Only cleanup deferred I/O if necessary
Commit 5a498d4d06d6 ("drm/fbdev-dma: Only install deferred I/O if
necessary") initializes deferred I/O only if it is used.
drm_fbdev_dma_fb_destroy() however calls fb_deferred_io_cleanup()
unconditionally with struct fb_info.fbdefio == NULL. KASAN with the
out-of-tree Apple silicon display driver posts following warning from
__flush_work() of a random struct work_struct instead of the expected
NULL pointer derefs.

| In the Linux kernel, the following vulnerability has been resolved:
ASoc: PCM6240: Return directly after a failed devm_kzalloc() in pcmdevice_i2c_probe()
The value “-ENOMEM” was assigned to the local variable “ret”
in one if branch after a devm_kzalloc() call failed at the beginning.
This error code will trigger then a pcmdevice_remove() call with a passed
null pointer so that an undesirable dereference will be performed.
Thus return the appropriate error code directly. |
| In the Linux kernel, the following vulnerability has been resolved:
net: ice: Fix potential NULL pointer dereference in ice_bridge_setlink()
The function ice_bridge_setlink() may encounter a NULL pointer dereference
if nlmsg_find_attr() returns NULL and br_spec is dereferenced subsequently
in nla_for_each_nested(). To address this issue, add a check to ensure that
br_spec is not NULL before proceeding with the nested attribute iteration. |
